摘　　要：新型的静止励磁调节器控制的双绕组异步发电机控制绕组无功容量的最小化是系统优化的关键问题,它与电机参数、负载、转速及变比、功率输出端励磁电容等有很大关系。在分析传统电容励磁的三相异步发电机变速变载运行机理的基础上,研究了变速变负载运行时控制绕组的无功容量最小化时励磁电容的取值方法。所得结论有助于该新型发电机系统的优化设计及控制。The minimizing to reactive power of control winding induction generator with static excitation regulator is key to optimization of system. It is determined by parameters of machine, load, rotating speed, speed ratio and exciting capacitors paralleled with the output terminal of power winding. Based on analysis about working principle of varying load and speed of conventional three-phase induction generator excited by capacitors, the determination of excited capacitors to minimize the reactive power of control winding under variable load and speed is given. These conclusions will provide theoretical guidance to the optimal design and control of generator.
