摘　　要：四桥臂并联APF用于解决配电系统中的电流谐波、中线电流过大和三相不平衡等电能质量问题。分析了四桥臂并联APF在各种非正常条件下的状态,得出了状态变化的机理,并通过仿真计算进行了说明,为设计四桥臂并联APF的保护措施提供了理论依据。The four-leg shunt active power filter （APF） is applied to improve the power quality in the distribution system. The behaviors of the shunt APF under all kinds of abnormal situation is analyzed,and the mechanism of state variation is achieved.Simulation results are given to show the validity of the analysis.The conclusions provide academic support for designing the safeguard measures for the three-phase four-wire shunt APF.
