New Head of Regulatory Affairs
and Technology for the UK
We are delighted to report that Colin Green has joined ABB in the new role of Head
of Regulatory Affairs and Technology for the UK.
Electricity Alliance Central wins
five-year substation contract
extension from National Grid
The New Year got off to a flying with the news that National Grid’s Electricity Alliance
Central (EAC), a consortium of ABB, Morgan Sindall and Atkins, has been awarded
a five-year contract extension to deliver major enhancements to the UK’s electrical
transmission infrastructure.
These enhancements will primarily
involve the design, construction and
commissioning of 400 kV, 275 kV and
132 kV transmission substations.
During the contract extension, which
runs until 2017, individual contracts will
continue to be awarded based upon
safety performance, cost, on time
delivery performance, project scope and
geographical considerations. It is therefore
not possible to place a total value on the
contract extension.
The EAC was established in 2006 as
one of National Grid’s preferred Alliance
partners for substation development and
4
construction projects. It operates in National
Grid’s Central region, comprising the
Midlands, Greater Manchester and
Liverpool. This original award was part of a
programme worth up to ВЈ2.8 billion to
upgrade and develop the electricity
transmission network across England
and Wales.
Stuart Grattage, Head of Engineering for
ABB Power Systems in the UK, said:
“National Grid’s decision to extend the
Alliance contract confirms the success of
our innovative approach where all four
participants work together as a true
partnership. This makes the best use of our
FFWD 1|12 Power Products and Power Systems
individual competencies and shares risk and
reward to create an effective team which
safely and efficiently delivers complex
substation projects, on time and on budget.”
Most recently, the EAC has been working
on one of the largest ever substation
projects undertaken in the UK, creating a
replacement 400 kV substation at Deeside.
Not only will this new substation play a
vital role in the reinforcement of the high
voltage transmission infrastructure in
northwest England, it will also pave the way
for the connection of a new high-voltage
direct current (HVDC) power link which is
under construction.
Colin has come to ABB after over 15 years
experience with the UK energy regulator,
where he was most recently Head of
Offshore Transmission Policy at the Office of
Gas and Electricity Markets (Ofgem). His
appointment expands the skills and
expertise that ABB can offer in the UK
power sector.
Colin’s main role is to support ABB in
building on its market leading position as a
supplier of advanced power transmission
and distribution solutions that are missioncritical to the future development of the UK’s
energy infrastructure. This will include
developing and extending ABB’s high level
relationships with key government policy
makers, industry bodies and customers to
promote the technical and economic
advantages of ABB’s world-leading power
systems technologies. Thanks to his wealth
of experience in the power transmission
industry, Colin is especially well placed to
promote, for example, the business case for
using ABB’s high-voltage direct current
(HVDC) technology to create the enhanced
infrastructure essential for the effective
integration of offshore wind power within
the UK grid.
Speaking about his new role, Colin said
“This is a great opportunity that enables me
to apply my knowledge, skill and experience
to support the growth of ABB’s UK
business. It is an exciting time to work in the
UK power sector with the growth of
renewable generation, the development
of smarter networks and the drive
towards more efficient production and use
of energy.
ABB is a company with a fantastic
culture and tradition and I am looking
forward to adding value to ABB and
its customers.”
“The UK energy market faces some key
technical and economic challenges over the
next few years” commented Stephen
Trotter, Head of ABB's Power Systems
Division in the UK. “Colin's appointment will
ensure that we can work pro-actively with
the various stakeholders – utilities,
developers, governmental and non
governmental organisations and financial
institutions, understanding the business and
regulatory environment and ensuring that
the market is aware of the value and
solutions ABB can provide across a range
of technologies – HVDC, energy storage,
smartgrids, network protection and control,
software, offshore wind, power generation,
energy efficiency, rail electrification and
tidal/marine.”

Power export cable for Humber
Gateway offshore wind farm
ABB has won a major order
from E.ON UK, to supply the
power export cables for
Humber Gateway offshore
wind farm.
The contract includes 2 x 14 km circuits of
132 kV 3-core AC submarine cable, with
integrated fibre optics and accessories, that
will connect Humber Gateway, one of the
UK’s largest offshore wind farms, to the
mainland grid.
When completed, in spring 2015,
Humber Gateway will consist of a 73 turbine
array that will generate up to 219 MW of
electricity, enough energy to power up to
170,000 homes. The wind farm will be
located 8 km off the East Yorkshire coast,
just north of the mouth of the river Humber.
The cable will be manufactured by ABB’s
factory in Karlskrona, Sweden, with delivery
scheduled during the summer of 2013.
New indoor high voltage substation
completed for Northern Powergrid
East Kilbride office established
ABB’s new office in East Kilbride now
provides a local hub in Scotland for our
Power Systems division. This effective local
presence will enable customers in Scotland
to access ABB’s state-of-the-art solutions to
support the major investments they are
making to expand and upgrade Scotland’s
electricity transmission, distribution and
renewable energy systems.
The office, at the Technology Centre on
the Scottish Enterprise Technology Park in
East Kilbride, will be the base for a number
6
of new ABB roles working on the full project
delivery – from inception, tendering and
design through to commissioning and
handover – of the many multi-million pound
schemes crucial to upgrade and enhance
Scotland’s high-voltage power transmission
and distribution infrastructure to integrate
the country’s fast-increasing level of
renewable energy generation.
The positions created initially in ABB’s
East Kilbride office will require considerable
additional labour market resource and
FFWD 1|12 Power Products and Power Systems
support, both directly from ABB and within
our wider supply chain, to be based on
construction sites throughout Scotland.
Although this is the first ABB Power Systems
office in Scotland, ABB already has an
established and thriving business in
Aberdeen, serving mainly the oil and gas
industries, as well as service personnel
located throughout Scotland. ABB is also a
major investor in Aquamarine Power, a wave
energy technology company with head
offices in Edinburgh.
ABB has handed over Northern Powergrid’s new 132 kV indoor GIS (gas insulated
switchgear) substation at Tynemouth following the successful on-time completion
of a turnkey design and build project.
The project has reinforced grid reliability and
ensured security of supply for the major
population centre served by the Tynemouth
substation by replacing outdoor AIS (air
insulated switchgear) equipment that was
nearing the end of its service life. The use of
ABB’s state-of-the-art compact ELK GIS
equipment enabled the new substation to be
built indoors, within a purpose-designed
building that occupies around one quarter of
the space required by the old substation.
Reinforcing our UK sales operation
We are pleased to announce that David Hughes, who was a wealth of experience in ABB’s UK operations, has been appointed
as our new Head of Front End Sales (FES) UK. He takes over the role from Richard Oulton who has moved to ABB’s High-Voltage
Marketing & Sales function in Zurich.

delivery. In fact, the whole process from
design, engineering, building the panels,
carrying out the FAT (factory acceptance
test) and shipping them to site was
accomplished in just three months.”
Flexible open system architecture
The adoption by ABB of the IEC 61850
standard offers significant technical
advantages through its flexible open system
architecture. These include a standardized
model of the IEDs and their data and
communication services, full interoperability
between electrical devices from different
vendors, reduced cabling and effective
future-proofing of the infrastructure by
making it easy to extend and update as
needs change.
The protection and control system for
Warrenby substation is based on IEDs
from ABB’s Relion® family of equipment
developed specifically to implement the
core values of the IEC 61850 standard. They
include Relion RET 650, RET 630 and
RET 615 transformer protection and
control devices. As an example of the
ease of integration with third-party
equipment, the scheme incorporates an
AVC (automatic voltage control) device
supplied by another manufacturer.
One of the key technical challenges
solved by ABB in designing the system
was to ensure that it meet the needs of the
engineering recommendation G59, that sets
out the standards required for the
connection of a generating plant to the
distribution systems of a licensed
Distribution Network Operator (DNO).
Rigorous FAT
The rigorous FAT for the Warrenby
panels was carried out at ABB’s unique
automated System Verification Simulator
(SVS) based at Stone, Staffordshire. Rather
than carrying out manual switching of
equipment to simulate the operation of
substation plant, the SVS is able to
duplicate the whole substation within
the test laboratory. It runs automated,
self-monitoring test sequences to provide a
high level of rigour and repeatability as well
as a full audit trail.
“Teesside Offshore Wind Farm is a vital
reference project that confirms ABB’s
capability to deliver IEC 61850 substation
projects” concludes Andy Osiecki. “It is
proof positive that this key new development
in substation design is now making the
transition from the laboratory to practical
real-world applications.”
IEC 61850 substation protection
and control scheme delivered for
Teesside Offshore Wind Farm
ABB has delivered a state-of-the-art substation protection and control system,
based on the IEC 61850 international standard for substation automation, for EDF
Energy Renewables’ Teesside Offshore Wind Farm.
The project for Warrenby substation,
the wind farm’s onshore connection
constructed by Morrison Utility Services, is
a significant development as ABB’s first UK
implementation of the global IEC 61850
standard that represents a major step
forward in simplifying the integration of
intelligent electronic devices (IEDs).
The offshore wind farm at Redcar,
Teesside consists of 27 turbines producing
8
power exported by 33 kV subsea cables to
Warrenby, where it will be stepped up by two
grid transformers to 66 kV so it can be fed
into the regional and national grids via the
Northern Powergrid network.
Complete protection and control system
Morrison Utility Services, the UK’s leading
utility service provider, awarded ABB the
contract to provide the complete protection
FFWD 1|12 Power Products and Power Systems
and control system for Warrenby substation.
According to Andy Osiecki, ABB’s General
Manager for Power System Network
Management, “the Teesside Offshore Wind
Farm project has been a significant
challenge, working not only with a new
customer, but also a whole new technical
approach that effectively required us to start
from a blank sheet of paper, and also
combined with the need to ensure fast-track
Safety by design features include special feet to improve cabinet
stability during assembly.

High Speed 1 power quality
project enters test phase
The start of on-line testing is a critical milestone in ABB’s project to
design, manufacture and install state-of-the-art capacitive compensation
systems for High Speed 1.
Flexibility is the key for smaller
substation projects
Jon Downs, General Manager Utility Substations, explains how ABB has replaced
the old �one size fits all’ approach with a new philosophy tailored to meet the needs
of smaller substation projects.
ABB is well known for its superb long term
track record in delivering major multi-million
pound turnkey substation projects, such as
Connah’s Quay – one of Europe’s largest
substations – which you can read about in
the other pages of this newsletter. What is
perhaps not so well appreciated is that we
are equally adept at working on smaller
value projects such as the delivery of
individual packages.
Listening
That is why over the past year or so we have
spent a lot of time talking to our customers
and importantly listening to exactly what
they need in terms of delivery models and
processes when we work with them on
lower level contracts. A clear picture
emerged that a �one size fits all’ service
simply isn’t appropriate. What is needed is a
totally flexible, tailored service that can
deliver the ideal response for each project.
10
An important change is reflected in the
adoption of multi-functional roles. This
means that the project manager might also
be the design engineer and then follow on
to be the site manager. While making these
changes, the over-riding concern is of
course to maintain the outstanding levels of
health and safety performance, on time
delivery and quality demonstrated on our
larger projects. In essence, the aim is to
deliver �big project’ performance for our
small project customers in a model that
meets their needs.
Encouraging results
We rolled out this new approach in 2011
and the results have been extremely
encouraging, both in terms of winning orders
and in the feedback from customers on our
tender submissions. The approach to small
projects is continuing to evolve as we create
a new team with the specific skill sets
FFWD 1|12 Power Products and Power Systems
aligned to the needs of this market,
especially in terms of flexibility, adaptability
and speed of response.
Upgrades and extensions
Typical utility substation projects that the
team is focusing on include upgrades
and extensions, such as circuit breaker
replacements, as well as system
integration or installation of equipment.
In fact, we anticipate that the need for
modification and extension of substations
is set to increase significantly as they
have to adapt to the increasing
demands of renewable energy sources in
the UK grid.
Overall, the message is that ABB now
has the flexibility to support any size of
substation project from ВЈ100k to ВЈ100
million. And for what some may describe as
a small project we still aim to deliver big
project performance and quality.
This involves running real trains – a Eurostar
and an Hitachi Class 395 – on a
representative section of the network to
confirm the capability of the ABB equipment
to prevent voltage drop issues on the
traction power catenary supply.
The 68 mile (109 km) High Speed
1 route, from the Central London terminal at
St Pancras International to the Channel
Tunnel at Dover, is used by Eurostar trains
operating the international high speed routes
between London, Paris and Brussels as well
as high speed domestic trains that
provide a commuter service between
London and Kent.
The High Speed route is supplied with
power on the 2 x 25 kV principle using
autotransformers. Its nominal line voltage is
therefore 25 kV. There are, however, some
sections of the line where it can drop as low
as 17.5 kV, causing a reduction in overall
system performance as well as spurious
tripping of the network protection and
control systems.
Voltage drop
The cause of the voltage drop is
the inherent design of the isolation
transformers (used to isolate between
High Speed 1’s AC traction power
supply and the adjacent Network Rail DC
traction power supply), located in
substations along the line. This is because
they require large magnetising currents
and
therefore
demand
substantial
inductive reactive power, which results in a
drop in the voltage supply as seen by the
train’s catenary.
A number of studies commissioned by
High Speed 1, including a detailed
investigation by ABB’s power quality expert
team based in Sweden, confirmed that a
reduction in the reactive power demand
from the isolation transformers will improve
system performance. ABB was then
awarded a major contract to design,
develop, manufacture and install a turnkey
capacitive compensation solution that will
effectively cancel out the inductive power
demand of the transformer, and hence
reduce the voltage drop.
Harmonic filters
The ABB solution for High Speed 1 is based
on harmonic band pass filters with a rated
output of 1512 kVAr, each comprising a
6.4 MVAr capacitor bank and a 303 mH
inductor. This equipment installation also
includes associated protection and control
equipment and a switch-disconnector that
enables it to be isolated from the network for
maintenance and repair.
A total of 17 capacitive compensation
filters have been installed at nine AC/DC
compounds at strategic positions along
the line.
“The strength of ABB’s technical solution
is of course vital to the success of the
High Speed 1 project. However, our overall
detailed, consistent and consultative
approach to the stakeholder management
of all the parties involved during the
construction and installation phases while
working alongside a live operating railway
network is just as important,” said Seamus
O’Neill, ABB Power Systems Operations
Manager for Rail. “For example, we worked
very closely with the High Speed 1 and
Channel Tunnel Rail Link (CTRL) System
Review Panel, who are responsible for the
introduction of all new assets, to ensure that
our project met their stringent technical and
operational needs.”
“Furthermore, during the equipment
delivery and construction phase the ABB
team worked very closely with High Speed
1’s own stakeholder management team to
support their efforts in liaising with local
authorities and residents to minimize any
potential disruption.”
Live tests
The ABB capacitive compensation filters
have already passed comprehensive
factory acceptance tests (FATs) and
pre-commissioning testing with flying
colours. Now, in the live test phase, trains
are being run between two selected points
on the High Speed 1 route to validate the
design and prove their capability, ready for
all nine sites to be put into full operation
later in 2012.

HVDC
HVDC
Hybrid HVDC breakers – a vital
breakthrough for Europe’s DC grid
Peter Jones, Engineering Manager Grid Systems for ABB UK, explains why the
recent announcement of ABB’s Hybrid HVDC breaker concept is a crucial
development in plans to create large DC grids.
As you can see from the other stories in this
newsletter, High-Voltage Direct Current
(HVDC) technology is well established in
applications such as bringing offshore wind
power to shore, supplying oil and gas
offshore platforms, interconnecting power
grids in different countries and reinforcing
existing AC grids. However, as the number
of these point-to-point HVDC connections
increases, it is becoming apparent that it
would be beneficial to connect them
the
through
than
rather
directly,
broader AC grid, as they are currently.
This is creating interest in plans for
HVDC supergrids.
The creation of an HVDC supergrid is a
considerable technical advance on single
route and multi-terminal HVDC schemes.
Multi-terminal HVDC installations have taps
along the DC line, however a true DC grid is
meshed and provides multiple power flow
paths between two points, and might have
single or multiple DC voltage levels. The
advantages of DC networks are in flexibility
and security, in addition to numerous capital
and operating cost incentives. Indeed, many
of the reasons for developing meshed AC
grids at the beginning of 20th century apply
now for enhancing HVDC into DC
transmission grids.
Hybrid HVDC breaker
For smaller regional grids, multi-terminal
HVDC technology is available and ready to
go now. However, in developing large interregional DC grids we need to achieve the
same levels of reliability and performance as
AC grids. This has not been possible until
now, due to the lack of a suitable DC
breaker for isolation of a faulted line or unit.
In fact, the relatively low impedance in the
DC grid means that, should a short-circuit
fault occur, the fault penetration is much
faster and deeper than in an AC grid. Fast
and reliable HVDC breakers, capable of
clearing a fault within a few milliseconds, are
therefore required to avoid a collapse of the
common DC voltage.
The existing mechanical HVDC breakers,
capable of interrupting DC currents within
several tens of milliseconds, are too slow to
fulfill the requirement of a reliable DC grid.
Furthermore, they are complex devices
passive
additional
include
which
components to create the resonance circuit
required to generate current zero crossing
for successful breaking of the current once
the contacts open.
Semiconductor-based DC breakers can
easily overcome the limitations in operation
speed but generate large transfer losses.
ABB has now taken the advantages of
mechanical and semiconductor designs and
combined them in a prototype hybrid
breaker that offers both fast operation and
reduced transfer losses.
ABB is also addressing a number of
other technical issues relating to multiterminal grids including:
• Power flow control
• Automatic network restoration
• DC/DC converters for connecting
different regional systems.
Fenno-Skan 2 commissioned
ABB has successfully commissioned the
Fenno-Skan 2 HVDC power link between
Finland and Sweden, a cable-based
that
system
transmission
power
enables the exchange of an additional
800 MW of power between the two
countries, mitigating transmission bottlenecks in the region. The Fenno-Skan link is
owned and operated by Fingrid and
Svenska Kraftnät.
The installation includes two converter
stations, one situated in Rauma, on the
Finnish side, and the other in Finnböle, in
Sweden. The control system of the original
link will also be upgraded. The newly
commissioned link will run in parallel with
Fenno-Skan 1, delivered by ABB in 1989
providing a bipolar link to enhance the
capacity for power trading and improve the
security of supply in the region.
Valhall offshore platform power
link completed
ABB has successfully commissioned an
HVDC Light link that enables onshore power
from Norway’s mainland grid to supply BP’s
Valhall multi-platform complex in the North
Sea. The new link allows BP to substitute
the use of offshore gas turbines to generate
electric power thereby eliminating up to
300,000 tons of carbon dioxide (CO2)
emissions a year - equivalent to the annual
emissions of around 125,000 modern
European cars.
The installation includes one converter
station onshore connected by an HVDC
submarine cable to a second converter on
the platform, about 294 km offshore. It
allows 78 MW of power to be supplied from
the mainland to run the field facilities,
including a new production and living
quarter platform.

Connecting Carrington Power Station
Design engineering drives Alliance success
Leigh Turley, ABB engineering manager, explains how design engineering is making
a significant impact on the delivery of high profile substation projects by National
Grid’s Electricity Alliance Central (EAC).
As well as being ABB engineering manager,
I am also the detailed design manager for
National Grid’s Electricity Alliance Central
(EAC), a consortium of ABB, Morgan Sindall
and Atkins, working on high profile
substation projects such as Carrington,
Cleve Hill and Connah’s Quay.
In the nearly two years I have been in this
role I have focused on introducing methods
that can help improve our engineering
performance, including reducing project
delivery times, lowering costs and improving
quality through increased standardisation
and repeatability.
Working across the diverse organizations
in the Alliance has presented a major
logistical challenge. However, we have all
pulled together to create a single delivery
team, learning from each other and building
on our individual strengths. Above
everything else, our success is based on
effective communication. One example of
this is the creation of a design standards
handbook that has been made available on
National Grid’s Livelink system to share
ideas and best practice relating to the
design of primary and secondary plant and
civil engineering.
I believe it is vital to keep building and
developing our engineering team to ensure
that we have the resource in place as our
substation business continues to develop.
14
We are committed to developing people
through training, for example we have
recently helped one of our layout engineers
to make the step up to become an
application engineer. Thinking ahead, we
have a very active graduate training
programme while we have just boosted our
intake of apprentices and they will add real
value to the business in four years time.
To supplement our resources we are
also working very closely with the ABB
team in Chennai who are now providing
excellent electrical engineering support for
primary layouts and protection and control
system design.
FFWD 1|12 Power Products and Power Systems
Design for safety
�Design for safety’ is a theme that runs
through all our engineering activities. One
area where some simple thinking ahead has
made a tangible impact is in improving
access to gas insulated switchgear (GIS)
buildings with access ramps that make it
easier to move test equipment in and out,
as well as reducing manual handling.
Lighting has also been brought down to a
lower level to eliminate hazardous dark
areas, and we are also using reliable low
maintenance lighting.
Attention to design has enabled us
to reduce the size of diesel generators
GIS installation at Carrington
Lean build approach for Carrington
Carrington Substation is a very high profile
project in which the EAC has built a new 7
bay 400 kV GIS substation that will enable
the connection to the transmission system
of the new CCGT power station that is being
built by Carrington Power Limited in Greater
Manchester. This project was used to
pioneer a lean building approach that has
enabled us to reduce the amount of �wet
trades’ required on site, such as concreting,
brick laying and plastering.
An important innovation was the use
of prefabricated relay rooms (PRRs).
This enabled all the protection and
control equipment to be assembled and
tested into a series of containers in the
controlled environment of our Stone
facility. The containers were then
transported
to
site
and
lowered

the installation and commissioning
process very fast and simple. Not only
does reducing the time we have people

reduces risk.
All that was then needed for the building

the site equipment.
Cleve Hill to connect the world’s largest
offshore wind farm
The lessons learned at Carrington were
applied in the construction of a new 400 kV
substation at Cleve Hill, near Faversham,
Kent. This will form a key element of the up
to 1,000 MW London Array – which will be
the world’s largest offshore wind farm when
it starts operation in 2012.
The Cleve Hill scheme required the
construction of a five-bay 400 kV GIS indoor
substation and associated infrastructure on
a greenfield site. The location of the
substation, which is cut into the side of
Cleve Hill, means that it is subject to strict
planning constraints with regard to its design
and size, and the project required careful
design and planning in order to gain
approval from the local authority.
Deeside – ABB’s largest ever substation
project
The jewel in the crown for the EAC is the
construction of a replacement for National
Grid’s 400 kV Deeside substation – the
largest ever UK substation project that ABB
has been involved in. The new substation,
scheduled for completion in 2018, will play a
vital role in the reinforcement of the highvoltage transmission infrastructure in
northwest England, and pave the way
for the connection of new high-voltage
direct current (HVDC) power links under
construction.
The project scope includes the
construction of a new 24-bay GIS substation
and the supply of key products like
switchgear and high voltage cabling, as well
as the integration of three 400/132 kV
240 MVA grid transformers and the
refurbishment of an existing unit. Not
only is the project technically challenging,
it also requires effective liaison with
multiple stakeholders such as National
Grid, International Power, SP Manweb
and EON.
One team, one goal
Within the EAC we have worked extremely
hard to integrate all the various different
types of engineers into a single delivery
team. The hard work clearly paid off, as
feedback from the tutors at the IET Power
Academy following a recent training exercise
was that they couldn’t tell which people
belonged to the individual Alliance partners,
since they all presented as one team with
one clear goal. And this teamwork has
brought its own reward with the recent
announcement that National Grid has
extended the EAC contract for a further
five years.

London Underground
The current major project to create a new Bulk Supply Point (BSP) for London
Underground (LU) provides a perfect example of ABB’s capability to deliver a
complete design, project management and construction service for rail substation
projects. This capability that not only includes all the electrical equipment, but also
cabling and the very substantial civil works required to create a new substation
building within an extremely restricted footprint.
20
FFWD 1|12 Power Products and Power Systems
Transport for London (TfL) has a number of
existing 132 kV BSPs that supply power for
LU. This additional BSP is now needed to
increase the available power to support
the full operation of new air-conditioned
rolling stock that, since 2010, is being
phased in on the sub-surface (SSL) lines –
the Circle, District, Hammersmith & City
and Metropolitan.
The BSP’s desired 120 MW capacity
dictated that it should be located relatively
close to a grid supply point. It also had
to be located close to the LU infrastructure
in order for the necessary cable
connections to be made between it
and the existing distribution system. The
most appropriate site for the new BSP
substation was identified adjacent to an
underground station.
Restricted site
The new BSP is designed to take electricity
from a nearby National Grid 400/132 kV
substation (constructed by ABB in 2004)
and step it down through transformation
(132/22/11kV) to feed into the LU power
supply system. In the past there were
houses and shops on the site, but they have
been long since demolished and most
recently, the site was used as a car park.
The major challenge for ABB has been in
working within this restricted site, hemmed
in on all sides with an operating railway
close by, to create a large, modern
substation building.
The project commenced in 2009, and
ABB has focused on the excavation and civil
works to create a new cable and switchgear
basements and multi-level reinforced
concrete building. The scale of this exercise
is illustrated by the need to remove 11,000
cubic metres of spoil materials – some 2,300
lorry loads. Extensive deep piling has also
been carried out to create the foundations.
This level of civils work in a busy area of
London has called for a very detailed
approach to logistics and communications,
not only with contractors and travel
authorities but also in ensuring minimal
disruption for the local community.
Electrical equipment
Following completion of the civil
works, ABB moved on to install the
electrical equipment. This includes: three
22/11 kV 25 MVA coupling transformers;
two 132/22 kV 120 MVA grid transformers;
a 35 panel 22 kV switchboard featuring
ZX2 GIS (gas insulated switchgear);
a 27 panel 11 kV switchboard featuring
UniGear AIS (air insulated switchgear);
LV switchgear; two 11 kV earthing / auxiliary
transformers; ventilation system and
associated mechanical systems; 110 V
batteries and charger.
A major project milestone was the
successful delivery and installation of the two
grid transformers, each weighing 97 tonnes,
completed over two weekends at the end of
2011. Transporting the transformers into the
centre of London and manoeuvring them
into position was a highly complex logistical
exercise requiring months of planning with
ABB’s transportation partner ALE (Abnormal
Load Engineering) to develop the optimum
installation methodology.
Stakeholder management
Equally important was detailed attention to
stakeholder management. This involved
working in close liaison with the local
council, police and residents to identify the
best route, arrange the necessary road
closures, traffic diversions, suspension of
parking spaces, removal of traffic lights and
signs to enable the two massive loads to
reach the site with minimum disruption.
The substation is also being provided
with new SCADA RTU (remote terminal
units) for the 11 kV and 22 kV switchgear.
Extensive fibre optic cabling will be installed
to provide the communication path between
the BSP, other substations and the LU
control centres.
In its first large scale cabling exercise for
LU, ABB is also carrying out cabling works
associated with the BSP including around
55 km of 22 k and 11 kV XLPE cable
installed in tunnels and ducts.
The new BSP project is
scheduled for completion
in the summer of 2012.

network maintenance and management costs.
The GridShield recloser enhances grid
reliability and efficiency by providing an

Reclosers combine a circuit-breaking
function with the ability to restore the power
automatically and quickly, so that temporary
faults are less likely to result in prolonged
power outages for utility customers.

New generation insulation material and
other important features
The use of hydrophobic cycloaliphatic
epoxy (HCEP) as insulation material
reduces the likelihood of flashovers and
insulator erosion.
The creepage performance of these
HCEP insulators is the best in the industry,
and far exceeds the requirements of ANSI
standards. In addition, it exceeds IEC Level
IV requirements for equipment operating in
polluted environments.
The magnetic actuators and vacuum
interrupters are rated at 10,000 full-load
operations. The actuators require no routine
lubrication, maintenance or adjustments;
and the bi-stable technology means no
power is required to maintain an open or
closed position.
No electronics are housed in the
interruption compartment, reducing unit
down time and eliminating the costs of line
switching when servicing the unit controls.
Single or triple-phase applications
Because there are three independent
actuators fitted in the cabinet, the GridShield
recloser can be used in single or triple-phase
tripping applications. The single phase
tripping capability reduces the number of
momentary interruptions caused by one
phase to ground temporary faults.
Why use reclosers?
A recloser is a protection device for
electrical distribution networks. It
combines a circuit breaker that trips
if an overcurrent is detected (indicating
a short circuit somewhere in a section of
the network), with an electronicallycontrolled reclosing function that
automatically restores power to the
affected line if the fault clears itself
quickly – which usually happens around
80 percent of the time.
There is a double incentive for
electricity distribution companies to
deploy reclosers in their networks. The
first is that reclosers prevent transient
short circuits from triggering prolonged
power outages. This results in better
supply continuity to customers. The
second benefit is that reclosers restore
power automatically, without requiring an
engineering site visit.
A transient short circuit is the type
of event that can be caused, for
example, when a branch of a tree
momentarily touches overhead cables
as it falls to the ground. Reclosers
handle this type of event much better
than circuit breakers. Typically, power
would be restored to customers in a
matter of a few seconds or less. Only if
the cause of the short circuit has not
cleared itself would the recloser keep
the breaker open until the cause is
manually cleared.
Reclosers like the new ABB
Gridshield also have electronic control
equipment with multiple network
interfaces, so the reclosers can be
integrated into a wider network
automation strategy. However, even with
a fast-acting recloser installed in
a feeder network, a transient short
circuit will still cause a momentary
interruption to customer supplies. But
this is much preferable to a power
outage that lasts until a maintenance
team can get to the breaker site to
restore power.

The project, featuring ABB’s state-of-the-art
UniGear primary MV switchgear, includes
the modification of the site’s single existing
33 kV circuit breaker and the installation of
an additional second circuit breaker to
ensure fail-safe operation.
Construction of Cwm Dyli commenced in
1906 to supply power for Wales’ then
prosperous slate industry. It also produced
electricity for the first ever transatlantic
transmission station set up by Marconi in
1912, near the village of Waenfawr,
Caernarfon. Water for the site comes
predominantly from the Llydaw lake some
320 metres above the site high on the
slopes of Mount Snowdon and travels to the
powerhouse through a two kilometre long
pipeline. The site was rebuilt in 1989 , when
the original Pelton wheel turbines were
replaced by a single Francis turbine capable
of producing 9.8 MW of green energy.
The new connection, comprising a 66 kV
site substation together with a 1.5 km
underground cable, will enable SITA UK to
feed an additional 21 MW of power into the
local grid via Northern Powergrid’s Tees
North substation.

Acids form as a result of oil degradation due
to oxidation, indicating that the transformer
oil is ageing. Corrosive sulphur is also well
known as a significant cause of premature
transformer failure as it reacts with copper
components to form highly conductive
copper sulphide that deposits on windings
and the paper insulation, causing a
breakdown of insulating properties and
resulting in shorting, arcing and even fires.
Deeside Power Station, which opened in
1994, is a 515 MW CCGT (combined cycle
gas turbine) power station owned by
International Power GDF Suez and sited by
the river Dee in Flintshire, North Wales. It has
three GSU transformers (two for each of the
gas turbines and one for the steam turbine)
that step-up the voltage produced by the
generator units to the 400 kV required by the
UK transmission system.
Oil tests carried out as part of a general
maintenance programme had indicated
increasing levels of acidity and the presence
of corrosive sulphur. The oil in each of the
three transformers had previously been
passivated using 7 litres (100 ppm) of
Irgamet 39. Subsequent tests showed an
unexpectedly high consumption of the
passivator so Deeside Power asked ABB’s
specialist UK transformer repair and
maintenance team to take further samples
and recommend remedial measures. These
new tests confirmed that the oil was in a
condition where it needed reconditioning or
replacement. The main aim was to remove
the acidity and sulphur that were reducing
the DP (Degree of Polymerization) value of
the paper insulation, which is an important
indicator of its remaining service life.
It was decided to use ABB’s unique online oil reclamation service to reclaim the oil
rather than replacing it with new. This
process enabled the acidity and sulphur to
be removed over a period of time with the
transformers remaining energized, so the
power station could continue to operate at
full capacity without the need for an outage.
Mobile oil reclamation rig
The reclamation process, in which the oil is
circulated continuously through ABB’s
mobile oil reclamation rig, housed in a
40 foot trailer, took around 10 weeks for
each transformer due to the large volume of
oil to be processed – a 190 MVA GSU
transformer, such as the units at Deeside
Power, holds 70,000 litres. The progress of
the reclamation process was monitored by
checking the colour of the oil as it changed
from a dark brown to a light straw colour. At
this point the oil was sampled for laboratory
testing to confirm the successful removal of
acids and corrosive sulphur.
Reclamation is superior to an
oil change
Initially, it might appear that carrying out a
complete change of the transformer oil
would be a faster and more efficient
method of eliminating the by-products
of oil degradation. However, extensive
laboratory and field tests carried out
by ABB have shown this offers only a short
term benefit as the new oil soon becomes
contaminated by the residual oil in the
tank and the insulation. So, while the
reclamation process is longer and slower,
it provides a permanent long-term solution
that restores the properties of the oil to
very near those of new oil by removing
acids, sludge and other degrading
products like corrosive sulphur. This also has
a beneficial effect on the ageing of the
paper insulation.
Taking an oil sample from a transformer

found that the harmonic currents present on
the network were causing the five capacitor
banks (5 x 50 kVAr) to degrade prematurely.
Not only was this reducing the operating
efficiency of the capacitors, during peak load
periods it was causing the main incoming
breaker to trip – a major concern for a site
where the reliability and availability of the
production lines are core to its business.
It was actually Paragon’s investment in
the state-of-the-art printing technology
required to maintain its position as the UK’s
largest manufacturer of self-adhesive food
labels that was contributing to the problem.
This is because advanced printing
equipment utilises variable speed drives
(VSDs) that are a notorious source of
network harmonics.
ABB’s detailed investigation established
that the total harmonic distortion (THD) on
the network was above the recommended
levels stipulated in Energy Networks
Association Engineering Recommendation
G5/4-1 – Stage 2 Table 12 �Planning levels
for harmonic current distortion and
connection of non-linear equipment to
transmission systems and distribution
networks in the UK’. If this issue, together
with possible system resonance, was not
addressed then the output of the existing
capacitors would continue to degrade over
a period of time, reducing the power factor
and allowing the site’s peak demand to
increase, with the possibility of further main
incomer tripping occurring.
The recommendation was to remove the
existing capacitors completely and replace
them with a 250 kVAr Advance automatic
capacitor assembly fitted with detuning
reactors to mitigate the damaging effects of
the harmonics. A year on from the
installation, the Spalding site is operating
efficiently with no reported tripping incidents.
Boston – harmonic filtration solution
Following the success of the Spalding
project, ABB was asked to investigate
Paragon’s Boston site. It was found that
again the harmonic distortion on the network
was outside the G5/4-1 recommendation.
ABB was able to offer the ideal solution in
the form of its new generation PQF (power
quality filter) family of active filters. They
operate by continuously monitoring the
current in real time to determine what
harmonics are present and then injecting
harmonic currents into the network with
exactly the opposite phase to the
components that are to be filtered. The two
harmonics effectively cancel each other out
so that the feeding transformer sees a clean
sine wave.
A 450 A PQFI unit designed specifically
for heavy industrial loads was installed and
harmonic distortion assessments carried out
following its commissioning confirmed that
the harmonics are now limited to well below
the G5/4-1 requirement.
Wisbech – PFC solution
At Wisbech, ABB was asked to help
improve the site’s power factor (PF).
PF is essentially a measure of how
effectively electrical power is being used.
Ideally it would be 1 (unity), and the
closer to this figure it actually is then the
more effectively electrical power is being
used and vice versa. The investigations
found that the PF of 0.845 lag was
well below acceptable industry standard
levels, which usually call for a PF of
0.95 or better. In fact, a site PF lower than
0.95 can now result in penalty charges
being imposed by the local electricity
supply company.
To rectify the situation, ABB installed
sophisticated power factor correction
(PFC) equipment in the form of its
Advance
400
automatic
capacitor
equipment comprising a total bank of
300 kVAr, complete with a detuning
reactor to eliminate any issues with
network harmonics.

Delivering energy efficient data centre
power from incomer to server
The developers and operators of today’s new-generation data centres make major
demands on their power network infrastructure. Downtime due to loss of power
simply cannot be contemplated, so operators insist on total reliability and availability.
ABB has responded by developing a unique comprehensive approach that covers
every need from the incoming supply through to the server racks. This includes all
the AC and DC systems, automation and services required to deliver reliable and
efficient solutions for a diverse range of data centre installations.

Rather than dealing with separate suppliers
for individual project elements, a data
centre developer can work with ABB to
meet all its power requirements from a single
source. This saves both time and money. It
also has the advantage that all ABB
equipment is guaranteed to work together
seamlessly, ensuring fast-track installation
and commissioning.
ABB’s scope of supply goes well beyond
grid connection, medium-voltage (MV) and
low-voltage (LV) switchboards, power
distribution units, protection relays and
transformers. It also offers variable speed
drives (VSDs), motors and power quality
equipment. This all comes with the
installation, maintenance and 24/7 service
support of a major global organization.
Grid Connection:
As an Independent Connection Provider
(ICP) registered under the Lloyds NERS
scheme, ABB can offer a turnkey solution for
contestable utility connections at all voltages
to include the integration of Air Insulated
Switchgear (AIS), Gas Insulated Switchgear
(GIS) and Hybrid solutions. ABB offers a
complete one-stop shop package for the
electrical distribution in data centres. ABB
can also provide �Rapid Build Substations’
that enable customers to have a grid
connection in the minimum time.
Medium voltage switchgear
ABB offers the full spectrum of both AIS and
GIS switchgear. With the growth in size of
data centres the full load current and fault
levels can increase dramatically. ABB has
the product range to cater for these and all
data centre applications.
An important element in ABB’s range is
the UniGear 500 R Fixed Circuit Breaker
panel, which is currently the most compact
air-insulated MV switchboard on the market.
A further advantage of the UniGear 500 R
is that it coordinates perfectly with the
well-proven UniGear ZS1 portfolio. So, for
example, it is possible to specify on the
same busbar: a UniGear with withdrawable
incomer; fixed circuit breaker outgoing; and
additional starter switchgear.
Relion range of relays
ABB has developed its Relion family of
IEDs (intelligent electronic devices) to
unleash the full potential of the IEC 61850
standard for communication, Power
monitoring and interoperability of substation
automation equipment. This new family
includes the Relion 615 relay that provides
absolutely selective protection, making it
ideally suited to data centre protection and
control applications.
DC power leads the way for data centre
energy efficiency
Data centres consume around 1.5% of the
entire world’s electric power. Given the
tremendous growth that the industry
continues to experience, energy efficiency
has become a top priority.
DC (direct current) powered data centres
are now being adopted across the industry
largely due to their cost advantage in terms
of both initial investment (less equipment)
and operating costs (greater efficiency). But
significant energy efficiency gains can also
be made in a variety of areas such as:
• HVAC efficiency – variable speed drives
and high efficiency motors can cut
HVAC costs by as much as 50%
• Facility efficiency – Electrical power
distribution design can reduce energy
wasted in the facility by up to 30%
compared to conventional designs
• Personnel efficiencies – instrumentation
can be configured from a central control
area, eliminating the need for engineers
to physically adjust the device
• Utility rates and billing – with the right
monitoring and control capability, data
centre operators can take advantage of
time-of-use rates and demand response
programs to lower electricity costs.

disconnector, which is integrated in the main
chamber, enables the following functions:
• Line disconnection
• Busbar disconnection
• Earthing of the line through the
circuit breaker
• Earthing of the busbar through
the chamber
The multifunctional PASS M00 module
can also integrate current and voltage
transformers, surge arresters and protection
and control systems. It is available for
single and double busbar configurations,
has a single and triple pole operating
mechanism option and is ideally suited
32
for use as a standard product in the
design of new modular substations or for
retrofit applications.
Wind farm applications
PASS M00 is ideally suited to high-voltage
(HV) wind farm collection grid applications
where it offers these advantages:
• Compactness due to full gas insulation
• Fast installation time (no HV test is
required on site)
• High reliability obtained through lean
design;
• Fast repair in case of faults due to
modular assembly
• Remote control provided by motor
operability;
• Easy combination with oil insulated, gas
insulated and dry power transformers.
A case study of new generation offshore
wind farms equipped with 5 MW turbines
FFWD 1|12 Power Products and Power Systems
revealed that the use of PASS M00 modules
in 72 kV collection grids made it possible to
fit a complete HV substation within a tower
with the following advantages:
• Reduction in the number of arrays
necessary to export the energy produced
• Reduction in the number of cables in
parallel for each feeder;
• Increase in the power capacity/current
ampacity of a single feeder;
• Reduction in the losses in subsea AC
internal grid array cables;
• Decrease in the voltage drop in the
feeder/string;
• Decrease in the short circuit value of
internal grid apparatus;
• Eliminate the need to construct an
offshore HV/MV platform substation
when offshore wind farms are close
to land
• Flexible internal configuration and
higher reliability
Supporting Macmillan Cancer Support
ABB recently celebrated its 12th year as a supporter of Macmillan Cancer Support,
during which time our UK employees have raised over ВЈ700,000 to help change the
lives of people affected by cancer.
Cancer is the toughest fight most of us will
ever have to face. But there is a team of
people who are there to support every step
of the way and that’s the Macmillan team.
They simply couldn't provide their vital
services without the people who support
them – people like you.
There are many ways that ABB staff has
got involved in the past year – some more
energetic than others! Among the more
energetic activities were two separate
climbing expeditions to conquer Kilimanjaro,
the highest mountain in Africa; a team
participated in the Great North Swim, the
UK’s biggest outdoor swimming event; and
others pounded 13 miles of Newcastle’s
streets to complete the Great North Run, the
world’s largest half marathon. Other more
gentle fund-raising activities included
the whole company participating in
Macmillan’s annual �Wear your Macmillan
t-shirt to work’ day.
Sharon Cottam from Macmillan Cancer
Support said of ABB’s fund-raising efforts:
“This is testament to the support from ABB
staff, raising yet another superb total in 2011
of over ВЈ28,000. I cannot thank ABB
enough. One in three of us will get cancer
and it’s the toughest fight most of us will
ever face. By joining Team Macmillan in
a fundraising event you're helping
support people and their families living
with cancer.”
Trevor Gregory, Managing Director of
ABB in the UK, said: “Our staff are
passionate about supporting such a
worthwhile cause as Macmillan Cancer
Support. Thanks to the efforts of our staff,
we are helping Macmillan to support cancer
sufferers, their friends and families. It’s both
humbling and rewarding but something ABB

Sponsorship sustained for IET
Innovation in Engineering Awards
Dolwin2 follows the success of the Borwin1 HVDC light project shown here
The wind farms will be connected with AC
cables to the HVDC converter station based
on an offshore platform situated in the North
Sea and further through 45 km of DC sea
cable and 90 km of land cable to the HVDC
onshore station at the grid connection point
at Dörpen-West.
The transmission system will have a total
capacity of 900 MW at В±320 kV, which
today is the world's largest offshore HVDC
system. The completed link will be capable
of supplying more than 1.5 million
households with clean wind-generated
electricity. The HVDC Light system that will
be used offers numerous environmental
benefits, such as electrical losses of less
than 1 percent per converter station, neutral
Event
A vital element in the DolWin2 project will
be ABB’s innovative, robust and scalable
GBS (Gravity based self-installing) platform
concept, developed in cooperation with a
leading player in the offshore sector to meet
the challenge of locating HVDC converter
stations in demanding offshore locations.
The new GBS design addresses key
issues such as efficient production and ease
of installation, as it requires only a minimal
level of offshore works, without the need for
a heavy-lift vessel or jack-up operations. The
design also offers complete flexibility within
challenging
installation
programmes,
as it can be installed in the waters of the
North Sea, and elsewhere, at any time
of the year.
