一种基于LCL滤波的APF控制方法研究
Research on Control Method of APF Based on LCL Filter
摘要
Abstract
The traditional control method adopts the form of centralized harmonic detection,this method has low precision and inflexibility. The control method which combined fractional harmonic detecting with feedforward compensation,was applied to the APF system based on LCL filter. This method accomplished tracking the reference current accurately by feedforward compensation. At the same time,it could flexibly decide which harmonic frequency and capacity to be compensated. Finally,the simulation and experiment results indicate the correctness and effectiveness of control method. The control method of fractional harmonic detecting combined with feedforward compensation produces a better compensation effect,the capacity of APF has also been fully and flexibly utilized.关键词
