Proportional-Resonant Control of Doubly-Fed Induction Generator Wind Turbines for Low-Voltage Ride-Through Enhancement
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
