基于反步法的双馈风力发电机直接功率控制策略

This paper presents a sort of nonlinear backstepping-based algorithm combining with direct power control (DPC) to a wind turbine-driven doubly fed induction generator (DFIG) under normal and especially harmonic grid voltage. First, the power control objectives are analyzed and designed under normal and harmonic grid voltage for the purpose of harmonic stator current suppression; second, a unified ...
