Abstract

This paper proposes a novel control strategy for Doubly Fed Induction Generator (DFIG) based wind power system and Permanent Magnet Synchronous Generator (PMSG) based wind power system during grid voltage dips. Based on a comparative study, the rotor over-current of DFIG and DC-link over-voltage of PMSG are identified as two main issues during grid voltage dips. A novel control strategy is proposed to enhance the wind farm Fault Ride Through (FRT) capability to some degree without additional devices, taking both grid code requirements and wind turbine requirements into account. A wind farm model consisting of DFIGs and PMSGs is built up. The effectiveness of the solution is demonstrated after simulation using MATLAB/SIMULINK.
