Abstract :
The application of a Dynamic Voltage Restorer connected to a wind turbine driven doubly fed induction generator (DFIG) is investigated. The setup allows the wind turbine system an uninterruptible fault ride through of voltage dips. The Dynamic Voltage Restorer 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 show the effectiveness of the Dynamic Voltage Restorer in comparison to the low voltage ride through of the DFIG using a crowbar which does not allow continuous reactive power production.
