摘要
本文介绍了双DSP控制下大容量有源电力滤波器二重化的研究,重点阐述了系统控制、谐波电流指令提取和试验情况。控制方法采用PWM直接控制电流的方法,控制策略以d/q坐标变换为基础,实行分次补偿。因采样和补偿系统造成的幅值和相位差,在谐波电流指令提取过程中进行了动态补偿。单机100kVA和二重化200kVA有源电力滤波器的实验结果证明了控制方法和控制策略的正确性。
This paper introduced the study of a high-power active power filter under dual DSP control, elaborated mostly system control and harmonic current instruction detection and test result. The PWM direct control current method is used, controlling strategy based on transformation in d/q coordinate,the harmonic current is compensated solely. The amplitude and phase error which are caused by sampling and compensation system is compensated in the process of harmonic instruction current detection. The result of single 100kVA and dual use 200kVA APF show that the control method and control strategy is very good .
