Laboratory Facilities
The Windlab is designed to allow low cost development of
prototype devices by providing equipment and modular devices to
emulate them as a full system. For example the wind motion could
be emulated by driving a generator in such a way that the
electrical output mirrors that of a wind turbine in any
situation for which a high frequency wind data set is available.
The Windlab will also be able to emulate grid conditions,
including grid faults and abnormal events like frequency
excursions. This can be connected to devices and prove control
or protection strategies
prior to implementation.
At present the facility comprises generators (two squirrel cage
induction machines (SINTEF) in a M-G setup with wind emulator),
power converters (two 25 kW Back-to-back power electronics
converters, 150 kW expected in March 2005), data acquisition
system, DSP based digital control and network components,
allowing testing of 55 kW generation devices in real networks. A
set of inductors to emulate weak and strong grids and a
thyristor controlled short circuit device to realize a safe
short circuit in the lab. The system is modular and flexible and
can be modified as experiments require. A variety of different
control strategies/options may be implemented. It also features
a complete set of instrumentation and power measurement
equipment.
The facility is a closed area that offers a high ceiling, a wide
entrance for large equipment and extensive safety features, a
ceiling mounted crane to handle up to 3 Tons. The electrical
installation is equipped with a variety of 3 phase, 380/220 VAC
50 Hz, 3 phase, 230/130 VAC, 50 Hz, and 110 and 220 VDC buses.
The facility need to be equipped with a line coming directly
from the power transformer to have a higher short circuit
capacity (> 2000 amps).
Through the cooperation with SINTEF, there is possibility to
access the Test Station VIVA AS with a 225 kW turbine and
2.3-3.0 MW turbines by 2005, which may be used for
data-validation and measurement comparison.
Through TTO a link to the market will be possible by providing
an integrated facility covering experimentation, certification,
demonstration and product launch facilities.
