1 MW drivetrain test facility
The objective of the drivetrain test facility is to investigate the behavior of the total system
from the main bearing near the rotor to the output into the electric grid. The setup includes
a 1MW driver nacelle that acts as motor to drive the test nacelle. The test nacelle is
connected to the driver nacelle via a drive shaft and connected to the grid. The facility
enables the measurement of loads on the shaft, bearings, gearbox of the nacelles during
the experimental testing of realistic wind turbine operating states such as fluctuations in
speed, torque, emergency shutdowns etc. The facility is also equipped with a flexible
support bed that can represent the flexibility of the wind turbine tower. The total setup
enables the study of different nacelle configurations as to their potential failure modes,
which in turn allows the design of gearboxes and transmission systems with improved
reliability.

Material testing: Microscopes (building 228)
The section Materials Science and Advances Characterisation (MAC) is focusing on
processing, structure, properties and performance of metals and alloys. In order to
produce materials with the required properties it is vital to control the microstructure. One
of the key techniques for studying the microstructure is electron microscopy. Electron
microscopy can identify voids, cracks, local inhomogenities, structural changes with a
spatial resolution down to the size of a single atom. Single sections through a sample can
be obtained and series of images can be used to reconstruct sample features in 3D.
Both conducting and non-conducting samples can be studied in both static and dynamic
experiments. Samples can be deformed or annealed in-situ. MAC has several different
sample holders for electron microscopy including a Hysitron Picoindentor that makes it
possible to study how individual dislocations are formed and propagate in materials.

DTU Wind Energy test wind turbine (Location M2)
Østerild - National Test Centre for Large Wind Turbines
In June 2010 the Danish Government passed a law in order to establish a national test
centre for wind turbines at Østerild, Thy where new wind turbine prototypes could be
tested. The Technical University of Denmark is appointed to be head of the establishment
and operation of the new wind turbine prototype test facility.
DTU Wind Energy is operating three wind turbine test sites in Denmark. The test sites are
situated at (1) DTU Risø Campus, Roskilde, (2) Høvsøre Test Site for Large Wind
Turbines at Lemvig and (3) Test Center Østerild at Thisted. At Høvsøre and Østerild, DTU
Wind Energy has in total 8 test stands.
Test Centre Østerild was established with 7 test stands during 2012 and allows for
erection of wind turbines of up to 210 and 250 meters respectively. For more information,
read the brochure about Østerild here.
The Test Centre's geographical location and facilities allow for the wind turbine industry in
collaboration with DTU and other research institutions to carry out research, development
and tests of prototype wind turbines and new wind turbine technology.
A grid connection test facility may be expected to be established at the Test Centre,
although not until 2014 at the earliest.
All stands have been rented out and the two new tenants are EDF Enérgies Nouvelles
from France and Vestas Wind Systems A/S from Denmark. Three wind turbines have been
installed and erected on stands 2, 3, and 7 at the Test Centre, and one on stand 6 has
been taken down again. Siemens Wind Power has one erected and a new one will be
installed, and Vestas Wind Systems have installed two wind turbines. More information
about the type of the turbines and hub height etc. see the link.

Test Centre for large wind turbines at Høvsøre
In the late 1990s Danish politicians decided to establish a test centre for large wind
turbines at Høvsøre, situated in Denmark on the west coast of Jutland.
In order to keep being in the forefront of the international wind energy sector it was of
primary importance to establish contemporary and future-proof test facilities that made it
possible to make measurements and test large wind turbines at high wind speeds.
The main objective with a national test centre was to develop and test new wind turbine
concepts and methods, gather data of tests performed on the wind turbines and document
safety, operational liability, cost-effectiveness and noise/acoustic resonance.
This was the main reason behind Risø’s (today DTU Wind Energy) motivation for
establishing a national test centre for large wind turbines in 2002. Thus safeguarding the
Danish wind turbine industry’s dominant position and providing them with the best possible
test facilities and other facilities for basic research within meteorology and wind turbine
technology.
During the 10 years existence of Høvsøre an innumerable amount of tests have been
performed on 19 different wind turbines and the demand for new tests and measurements
on turbines at the test centre at Høvsøre will continue.
At Høvsøre the wind conditions allow an almost uninterrupted wind speed coming from the
North Sea and it reaches the wind turbines at a very high speed corresponding to the
turbines erected offshore. The flat terrain west of the test centre means that the wind
conditions at the turbines are very well defined. A measuring mast is standing west of each
wind turbine and a meteorology mast is situated south of the test stands. Furthermore, two
165 meters high light masts have been constructed to the east of the test stands row and
they mark the maximum height of the whole area.
Wind speeds, wind direction, temperatures, and atmospheric pressure are being
measured on all masts, and a few of the masts provide measurements at different heights.
An average wind speed of 9.3 m/s has been measured at the height of 80 meters. All data
is continuously gathered, and quite a few is compared to measurements performed on the
wind turbines. Wind measurements from Høvsøre may be observed online on the web
site, here: http://www.vindenergi.dtu.dk/english/About/Hoevsoere_uk
