The novel dual stator-winding induction generator with static excitation regulator is presented as variable speed stand-alone power supply. The minimizing to reactive power of the static excitation regulator of control winding is key to optimization of system. Optimal design strategy for dual winding induction generator with variable speed via optimizing simultaneously the parameters of machine and the excited capacitors paralleled with power winding is presented. The expression of control winding current is deduced. The choosing principle of winding structure to decouple the leakage reactance between the d and q axes of the two sets of windings is proposed. The magnet circuit design feature with variable speed is discussed, and the optimal mathematical model with Aircraft power characteristic is proposed. A dual winding induction generator is designed by complex method with dynamic full reflection and retraction operator. The results show this scheme is valid to reduce reactive power of control winding excitation regulator and the cost, dimension of the system.
