Abstract

In this paper, a novel control strategy based on an inverse system method for supply-side converter used in VSCF wind power is proposed. First, a nonlinear model of supply-side converter is founded, and then the inverse system is obtained. With this control law, the DC link voltage can be kept at the value expected and the power factor is regulated unity. The operation under unbalanced line voltage is also studied. The simulation and experimental result verified the validity of the control law proposed in the paper for VSCF wind power.
