The excited reactive power of dual stator-winding induction generator has tremendous connections with parameters of machine, load, speed and its variable ratio and excited capacitors of power winding output port. The change laws of excited current and excited power of control winding with variable speed under rated load and no-load are analyzed in this paper, and the laws of excited current and excited power of control winding with leakage inductance, excited inductance, excited capacitor were explored. The results helped to the optimal design of the dual stator-winding induction generator.
