摘　　要：由于电网非线性负荷及各种时变电力电子装置的大规模应用,解决由此引起的谐波电流注入电网的问题已成为电力系统研究中的热点问题。该文分析有源滤波器的基本原理,基于ip-iq检测法和滞环控制,用PSCAD仿真软件建立一种新型有源滤波器模型,并应用该滤波器对谐波源所产生的谐波电流进行滤除仿真及实验分析。仿真及实验的结果表明:该有源滤波器对谐波电流有较为理想的滤除作用。Because of non-linear load of the power network and various time-varying power electronic devices for large-scale applications, how to solve the harmonic current injected into the power system has become a hot issue in the research of the electric power system. Basic principle of active power filter was analyzed firstly, and then based on ip-iq detecting method and hysteresis control, a new active filter model was proposed through PSCAD simulation software. It was analyzed for applying this active filter model to harmonic current generated by harmonics sources. Simulation results and experiments show the proposed method has a better filtering effect on the harmonic current.
