摘要

为了实现三相不平衡谐波的补偿

采用3个单相有源滤波器的星形连接组合成1个三相四线制有源滤波器。采用数字移相方法由单相电流虚拟出两相电流

进而利用瞬时无功功率理论实现了单相系统谐波电流的检测;建立了三相四线有源电力滤波器的仿真模型

研究了不同接线方式下三相四线有源滤波器的应用特点。开发了有源滤波器实验系统

结果表明三相四线有源滤波器能有效滤除系统中的不平衡谐波。

Abstract

For achieving compensation of three-phase unbalanced harmonics

one three-phase fourwire active filter is composed by three single-phase active filters in Y-connection. Two-phase current is simulated by digital phase shifting method

and the detection of harmonic current of single phase system by way of instantaneous reactive power theory is realized. The simulation model of threephase four-wire active power filter is established and application features of three-phase four-wire active power filter at different wiring modes are studied. The experiment system of the active power filter is established. It is shown by the result that the unbalanced harmonic in the system can be filtered effectively by the three-phase four-wire active filter.
