Harmonie current suppression for DFIG based on PR controller

In recent years, As more and more attention to wind energy, wind power technology has become a hot research. This paper take the Doubly-Fed Induction Generator(DFIG) as the target for research. After theoretical analysis of the DFIG under harmonic distorted grid voltage conditions, we found the current of DFIG both in the stator side and rotor side will be distorted. And it will also make against to the active and reactive power in stator side and output torque of DFIG too. In order to eliminate these adverse effects, this paper proposes a control strategy based on the proportion-resonant (PR) controller firstly. Then build the simulation model by MATLAB/Simulink. Finally, simulation results verify the performance of the proposed control strategy.
