摘要：

This paper presents the control strategy of power winding voltage for performance improvement of the dual-stator brushless doubly fed induction generator (BDFG) under stand-alone nonideal load conditions. The control target is to eliminate the unbalanced fifth-and seventh-order components so that a pure and sinusoidal voltage at the point of common coupling can be obtained. Considering the existence of both dc and ac components in the control winding current reference, a proportionalintegral dual frequency resonance current regulator is adopted and tuned. The dynamic performances of voltage and current loop are also analyzed. Finally, the effectiveness of the proposed control strategy under various load conditions is verified by steady-state and dynamic performance tests.
