Abstract：To improve the dynamic performance of the dual stator-winding induction generator (DWIG) variable frequency AC generation system with inductive or capacitive loads, the feed-forward loop of load reactive power is added in the previous slip frequency control strategy. According to the instantaneous power theory, the active and reactive load power are calculated to respectively control the frequency and amplitude of the output voltage of the power converter quickly by the feed-forward loop to fast regulate the reactive power in the control winding, so that the slip frequency and the air-gap flux of the DWIG are adjusted quickly. Therefore, the power balance and output voltage constant are implemented. The experimental results prove the correctness and validity of the proposed strategy.
