摘　　要：对混合型电力滤波器的性能进行了研究,分析了其工作原理和性能.用基于自适应原理的检测方法检测出待补偿的电流值,采用改进的三角波调制电流的控制方法,使逆变器产生出待补偿电流,以减小因电气化铁道(简称电铁)牵引负荷给电力系统带来的谐波影响.同时在MATLAB的仿真软件下,利用电铁牵引供电系统中混合型滤波器进行谐波抑制的仿真模型,验证了该方案的正确性和可行性.This paper presents the performance analysis of a hybrid filter and discusses the principles of operation of it for restraining current harmonics and improving power factor compensation. In the APF, the compensation currents are detected by means of the method based on the self-adaption technology, and the currents for compensation are obtained from the inverter under the control of modified triangle-wave modulation current control. The simulation of electrical railway system model is presented with MATLAB using hybrid power filter, and the simulation results show that the method is feasible and effective.
