一种混合有源滤波器的设计及仿真

Design and simuulation of one hybrid active power filter

提出一种结构简单、实用性比较强的拓扑结构,分析了混合有源滤波器(HAPF)各部分器件参数选取的方法,其次对基于瞬时无功功率的i p iq方法进行分析。将广义积分控制器引入电流补偿控制环节中,并通过仿真对比,验证了在跟踪变化的周期信号时,它的稳态精度与动态响应速度都比传统的PI控制器具有优势。

This paper introduced a simple, practical kind of topology importantly. It analysised the parameter selection methods about each part of HAPF, then it significantly discusses the ip-iq method based on instantaneous reactive power. The generalized integral controller is applied to the current compensation control link, it is superior to the traditional PI controller at the point of steady-state accuracy and dynamic response when tracking periodic change signals, that is verified by simulation.
