有源电力滤波器中谐波检测算法分析与参数设计

有源电力滤波器控制的关键技术之一就是谐波检测,如何快速准确的检测出负载电流中的谐波成分是有源电力滤波器设计与实现中的一个重要部分。文章针对ip-iq法在实际应用中的不足进行了分析与改进,改进后的算法能够适用于三相三线、三相四线制系统,并能够分别检测出任意次零序、正序、负序谐波分量,针对改进后的算法进行了滤波器的参数设计,最后给出了在Matlab中仿真测试得到的结果。

Analysis and Parameters Design of Harmonic Detecting Arithmetic in APF

Harmonic detection is one of the key techniques of APF's controller,how to detect the harmonic detection quickly and truly becomes an importance department in the designing and implement of APF.In this paper,an improved ip-iq arithmetic of harmonic detection has been analyzed and designed to complement the shortages of classical ip-iq arithmetic,The improved arithmetic can used both in three phase three wire system and three phase four wire system.Positive,negative and zero phase sequence of random harmonic...
