Because of the converter in power electronic equipment, the step and speed of electromagnetic transient simulation for doubly-fed induction generator(DFIG)based wind turbine is small and slow. In order to realize the rapid electromagnetic transient simulation of DFIG based wind turbine, the unified simplified equivalent model of controlled source converter is proposed with consideration of averaged switching function, Crowbar protection circuit switching and converter locking transient processes. A predictive correction method for modulation is put forward, then the rapid electromagnetic transient simulation model of DFIG based wind turbine is established based on the equivalent model. Finally, taking 1. 5 MW DFIG based wind turbine as an example, the validation of proposed model is carried out by PSCAD/EMTDC simulation software from model correctness, simulation step adaptability and simulation speed. The simulation results are compared and analyzed, which prove the applicability of the rapid electromagnetic transient model in different application scenarios.
