有源电力滤波器两种检测算法的比较研究

A Comparative Study of Two Different Detecting Approaches of Active Power Filter

文章研究了有源电力滤波器的两种谐波电流检测算法,ip-iq法对负载电流中的谐波进行全部检测,基于用户侧谐波和无功补偿的检测法仅对用户自身造成的谐波进行检测。仿真结果表明,通过APF补偿后,前者电源电流为正弦波,后者电源电流和电源电压保持相同的畸变率,波形相似。

This paper presents a comparative study of two different detecting methods for an actice power filter. One is ip-iq method, that detects all harmonics of the loads, the other is an algorithm for compensation of customer-generated harmonics and reactive power, that only examines customer-generated harmonics and reactive power. Simulations show compensated source current is sinusoidal by the first approach. The resultant source currents have similar level distortion and wave of the supply voltage by the secend one.
