Power System is a standalone system
comprising
electrical
power
generation,
distribution and consumption. It’s purpose is to
provide extremely reliable power supplying for
oil drilling, processing and shipping facilities.
The owner is Al Furat Petroleum Company
(AFPC) Syria. Area covered by the distribution
network is some 100 km2. The power system
includes: 18 distributed generators with dual fuel
turbines (gas/diesel) and total of 200MW power,
double 66kV overhead lines to 4 major remote
sites, about 75 large consumers and 400 major
devices (transformers, breakers, motors, etc)
requiring supervision and automatic control..

Supervision & Control of all major Power
System equipment from central place in Omar
Control Building - Control Room.
Ensuring quality - voltage and frequency
stability.
Ensuring availability - load shedding
functions preventing black-outs and
disturbances in vital production facilities.
Ensuring efficiency - coordination of
generators, optimizing and fault finding tools
(reports, trends, process overviews, event &
alarm lists, system status, system list, ...).
Integration of 11 external control subsystems
in the DCS (various dedicated PLCs) via serial
links.

POWER GENERATION & DISTRIBUTION SYSTEM - “OMAR” in Al Furat oil fields - Omar, Syria
Automation and control system
Scope
Entire power system is controlled by process controllers and runs fully automatic. Each
part of it can be
controlled and monitored from any operator station. Control includes: breakers, transformers, motors and
whole subsystems like Fuel (gas/diesel) system, Instrument air, Water treatment, Fire water, etc .
POWER MANAGEMENT SYSTEM (PMS)
PMS is a group of dedicated programs in ABB DCS controller.
Main PMS functions are:
• monitoring interconnection status of the power system
• coordination of generators, frequency/voltage regulation
• calculation of consumption per load, island, area and site
• monitoring spare capacity of running generator sets
• shedding (disconnecting) preselected loads within 100ms
• disabling start of large loads if exceeding spare capacity
• monitoring and recording power consumption peaks
• warning and suggesting messages for the operator
• reports: production, consumption, running hours, peaks, ...
Features
DCS includes features like: redundancy (at all levels), MODBUS serial links, GPS time sinchronization,
long term data storage, alarm acknowledge recording, data logging and trend displays, operator’s
multilevel authority system (login + password), training system,...

POWER GENERATION & DISTRIBUTION SYSTEM - “OMAR” in Al Furat oil fields - Omar, Syria
Operator screen
example:
“OM_HV2001L”
presents electrical
distribution detail - 20kV
left busbar in Omar with
2 “Frame 6” generators.
Measured values are
updated each few
seconds.
Indications of breakers
position and status are
simple and selfexplanatory.
To change breaker
position, operator
selects it on the screen
and than uses keyboard
(or track-ball unit) to
issue relevant openclose command.

Operator screen
example:
“Turbine and Generator
overview” shows actual
process values and
main parameters.
Status is indicated with
texts and symbols.
Operator’s orders are
issued from the
screen/keyboard e.g.: to
start/stop the turbine
operator merely acts on
“Start” screen pushbutton in group “Master
control”.

Duration and results
In the period December 1996 - July 1997, 5 Intea’s
engineers worked on site (in shifts) until successful
handover.
INTEA’s work was recognized, by ABB project
leader/manager and end-user AFPC, as outstanding
and highly professional.
Post start-up activities - Intea
1.) October 1998. - “Residence engineering” contract.
Two Intea’s engineers (back-to-back) during 6 months
held operation and maintenance training courses for the
client.
2.) May 1999. - “Y2K upgrade” project. DCS’s Year
2000 compliance ensured.
Project expansions awarded to Intea
1.) February 2000. - “Maleh expansion” project. New
AC450 programming and integration in Omar system.
2.) April 2000. - “Omar extension” project. Major DCS
modifications to support: new “Frame 6” generator, new
load shedding principle, new process sections,....
3.) May 2002. - “Tanak extension” project. Major DCS
modifications to support: 2 new busbars, 22 new
objects, 6 new shedding loads, (4 start inhibitions).
Modifications: node 7, node 3, OS. Application
extension on OMAR location. Modifications: node 1 and
node 3.
