英文摘要：

The minimizing of capacitance ratio between control winding and power winding of dual-statnr winding induction generators is important for the cost and size reduction. It is necessary to analyze the changing of the main parameters which greatly influences the performances like capacitance ratio and efficiency. The equivalent circuit and performance calculating method were given, and the laws of influences were proposed. These conclusions provide theoretical guidance for the optimal design of generator.
