The control winding connected with excited converter only supply excited reactive power of dual stator-winding induction generator. The speed has a wide range with wind power and airplane supply system. The mini?mize the reactive power of control winding can reduce cost of generator system. The excited capacitor of power winding influences the reactive power of control winding. In this paper, the determination of excited capacitors to minimize the reactive power of control winding under variable load and speed are analyzed. The influences of machine’s parameters were analyzed.
