摘要
介绍了10kVA三相四线制并联有源电力滤波器(Shunt Active Power Filter,简称SAPF)的研制、系统构成和工作原理,以及采用负载基波电流作为参考电流的新型控制模式。设计了基于DSP和CPLD的控制电路,最后给出了实验结果。实验证明,该系统能有效补偿非线性负载产生的谐波,不仅补偿精度高,而且动态性能优良。
This paper deals with the design and implementation of a 10kVA shunt active power filter used in threephase four wire system.The system configuration and working principle are introduced, the new control mode is adopted by load fundamental current as reference in place of load harmonic current.Then the hardware circuit is designed based on DSP and CPLD.At last,some experimental results verify the validity,effectiveness and good dynamic performance of the active power filter.
