Abstract

A novel control method is proposed for the three-phase four-wire four-leg active power filter (APF) to realize the accurate and real-time compensation of harmonic of power system, which combines space vector pulse width modulation (SVPWM) with triangle modulation strategy. Firstly, the basic principle of the APF is briefly described. Then the harmonic and reactive currents are derived by the instantaneous reactive power theory. Finally simulation and experiment are built to verify the validity and effectiveness of the proposed method. The simulation results show that the response time for compensation is about 0.025 sec and the total harmonic distortion (THD) of the source current of phase is reduced from 33.38% before compensation to 3.05% with APF.

基于SVPWM和平均电流法的三相四线四腿有源滤波器控制

提出了一种将空间矢量脉宽调制(SVPWM)与三角调制策略相结合的三相四线四腿有源电力滤波器(APF)控制方法，以实现电力系统谐波的精确实时补偿。首先，简要介绍了有源滤波器的基本原理。然后利用瞬时无功功率理论推导出谐波电流和无功电流。最后通过仿真和实验验证了所提方法的有效性。仿真结果表明，补偿后的响应时间约为0.025秒，相源电流的总谐波失真(THD)由补偿前的33.38%降低到有源滤波器的3.05%。
