Abstract

In this paper, the application of a series grid-side converter (SEGSC) connected to a wind-turbine-driven doubly fed induction generator (DFIG) is introduced. The setup allows the wind turbine system an uninterruptible fault ride-through of voltage dips. The SEGSC can compensate the faulty line voltage, while the DFIG wind turbine can continue its nominal operation as demanded in actual grid codes. The simulation results for the 2 MW-DFIG wind turbine system with the SEGSC compensation are presented, especially for asymmetrical grid faults, gives as good performance as those without grid faults.
