摘　　要：电力电子装置的使用数量在不断增多,随之而来的是日趋严重的谐波污染问题。目前,混合型有源电力滤波器已成为研究的热点。对基于瞬时无功功率的两种谐波检测方法进行了详细分析,突出讨论ip-iq方法在三相不对称负载中的应用问题。为了实现HAPF的电流无稳态误差跟踪控制,将广义积分控制器引入电流补偿控制环节中,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。More and more electrical equipment are in use. Hybrid active power filter has become a study focus these years. The two kind of harmonic detecting methods based on instantaneous reactive power are analyzed in detail. We discuss the ip-iq method which is used to deal with the problems of three-phase asymmetric load. In order to realize no steady state error tracking control about current of HAPF,the generalized integral controller is applied to the current compensation control link,which 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.
