Abstract :
Abstract — The application of a dynamic voltage restorer
(DVR) connected to a wind-turbine-driven doubly fed
induction generator (DFIG) is investigated. The setup allows
the wind turbine system an uninterruptible fault ridethrough
of voltage dips. The DVR can compensate the faulty
line voltage, while the DFIG wind turbine can continue its
nominal operation as demanded in actual grid codes.
Simulation results for a 2 MW wind turbine and
measurement results on a 22 kW laboratory setup are
presented, especially for asymmetrical grid faults. They show
the effectiveness of the DVR in comparison to the low-voltage
ride-through of the DFIG using a crowbar that does not
allow continuous reactive power production
