摘　　要：双馈电机驱动的飞轮储能多功能柔性功率调节器(FPC)中的电机可看作转动惯量很大且不带机械负载的双馈电动机或不带原动机的双馈发电机,能快速调节有功功率和无功功率,从而提高电力系统稳定性。在分析其启动和运行控制策略的基础上,设计一套额定容量为10 kV·A FPC励磁控制系统。对所提控制方法进行实验研究,实验包括对系统的启动特性、稳定运行后稳态和动态性能等,结果表明,该系统能够实现软启动,输出有功、无功功率可以独立调节,适合于带飞轮储能的双馈电机励磁控制系统。The motor of a doubly-fed induction machine(DFIM)driven multi-functional flexible power conditioner(FPC)can be treated as a doubly-fed induction motor with a large rotating inertia and without mechanical load or a doubly-fed induction generator without motor.It can regulate the active and reactive power rapidly to enhance the stability of power system.Based on the analysis of control strategy,a 10 kV·A excitation control system of FPC is developed.The proposed control method is experimentally running.Experimental results show that soft start can be implemented,and active/reactive power can be regulated independently.The excitation control system can be applied to a flywheel type FPC system.
