Abstract :
Effects of lower order harmonic grid voltage on the stator current of the Doubly Fed Induction Generator (DFIG) are investigated. A stator harmonic current control method for DFIG wind power system is presented to suppress the effects of the lower order harmonic grid voltage on the stator current. The proposed control scheme is analyzed using transfer function. The performance of the proposed control method is verified by both simulation and the experiment on a DFIG wind power system prototype.
