摘　　要：叙述了有源电力滤波器APF(Active Power Filter)的基本原理,分别介绍了组成APF的谐波和无功电流检测电路、补偿电流发生电路的构成和功能,在此基础上,介绍了常用的APF的谐波和无功电流检测方法、补偿电流控制方法和直流侧电压控制方法。为了验证APF的补偿功能同时加深对其控制方法的认识和理解,用Matlab 6.5/Simulink下的SimPower Systems Blockset对整个三相并联电压型APF系统进行了仿真研究。仿真结果表明,电压空间矢量脉宽调制SVPWM(Space VectorPulse Width Modulation)控制的APF能对负载电流中的谐波和无功分量进行快速精确的补偿。The basic principle of APF（Active Power Filter） is introduced,including structures and functions of harmonic ＆ reactive current detection circuit and compensation current generation circuit, based on which,methods of harmonic ＆ reactive current detection,compensation current control and DC voltage control are introduced. To verify its compensation function and further understand its control methods,a whole three-phase shunt voltage APF system is simulated using Simpower Systems Blockset in Matlab6.5/Simulink. Simulation results show that,APF controlled by SVPWM（Space Vector Pulse Width Modulation） can quickly and precisely compensate the harmonic and reactive components of load current.
