串联混合型有源滤波器研究现状及展望

有源滤波器在电能质量治理方面有着举足轻重的作用,硬件成本高、容量小、损耗大等缺点使传统串联混合型有源滤波器(series hybrid active power filter,SHAPF)发展缓慢,但随着电力电子技术的发展,新技术、新方法得到工程应用,SHAPF技术得到更多关注。着重总结了前人对SHAPF的四种拓扑结构、电流检测、跟踪控制技术等几个方面的研究,提出新的如功能兼容性等研究方向,为串联混合型有源滤波器的控制技术改进优化和工程应用提供参考。

Research status and prospect of series hybrid active power filter

Active filter plays a pivotal role in the field of power quality management.Compared with the parallel hybrid active power filter,series hybrid active power filter (SHAPF) develops slowly because of the inherent shortcomings.As the rapid development of power electronics technology,new technology and new methods have been applied in engineering field and SHAPF technology has attracted more attention from enterprises and universities.In order to provide a reference for the control technology improvements and engineering application of SHAPF,this paper mainly summarizes the previous researches on SHAPF topological structure,current detection and tracking control technology,and proposes new research directions such as functional compatibility,which can provide references for the improvement and optimization of control technology of series hybrid active filter and engineering application.
