摘 要: 提出了一种适用于电气化铁路谐波及无功综合治理的单相并联型混合电力滤波器 (PHAPF) ,该PHAPF是由采用可控硅阀投切的无源滤波器与有源滤波器串联构成的。介绍了PHAPF的结构、谐波检测及其复合控制策略。复合控制器中引入了递推积分器和有源滤波器输出电压反馈校正控制 ,实现了谐波反馈补偿控制及有源滤波器最小运行容量控制。仿真结果表明 ,所提出的混合滤波器及其控制策略不仅有良好的谐波、无功补偿性能 ,而且性能 A single phase hybrid filters are presented in this paper, which are used to compensate the harmonic current and reactive power caused by AC DC type electric locomotive in power systems. The configuration design and harmonic detection with notch digital filters are also presented in this paper. A high performance integral controller is achieved. There are recursive integral controller and the APF output voltage feedback compensating control, which realize harmonic current feedback compensation and APF minimum operation VA rating control. The simulation results show that the developed PHAPF and control strategies give satisfactory performance in harmonic and reactive power compensation.
