Some Controlling Strategies of DFIG to the Grid Turbulence

Abstract:

The paper introduces several methods about controlling strategies of DFIG to the gird turbulence. They could reduce the torque pulsation. They have better dynamic adjustment performance than the positive, negative sequence dual current control strategy. Stator current THD is well controlled. The experimental results show that it can smooth the DFIG active power output comparing with the traditional maximum wind energy tracking control strategy, significantly reduces the speed fluctuation of synchronous generator. The dynamic performance is improved.
