基于负载电流检测的并联型APF仿真研究

An Emulation Study of the Parallel APF Based on Load Current Detection

有源电力滤波器(简称APF)技术是一种实现电网谐波补偿、改善供电质量的重要方法。并联型APF大多适合于抑制电流源谐波。文章在前人并联型APF研究成果的基础上,利用Matlab工具箱,建立了基于负载电流检测的并联型APF仿真模型,并进行了仿真研究,仿真结果证明了该控制策略的有效性。

Active Power Filter （APF） technology is one of the important ways to realize harmonic wave compensation of electrical network and improve the quality of power supply. Parallel APF suits mostly curb harmonic waves. This article, based on the research results before and using Matlab magazine, has established an emulation model of the parallel APF based on load current detection and did some emulation researches, which is proved feasible.
