Abstract: A novel control strategy is proposed in this paper for the rotor side converter
(RSC) of doubly-fed induction generator (DFIG)-based wind power generation systems. It is
supposed to enhance the low-voltage ride-through (LVRT) capability of DFIGs during
great-level grid voltage dips. The strategy consists of a proportional-resonant (PR) controller
and auxiliary PR controllers. The auxiliary pensate the output voltage of the
RSC in case of gr
