摘要

控制有源电力滤波器（APF）直流侧电压为适当值是保证其具有良好补偿性能的一个重要因素

以并联型有源电力滤波器交流和直流侧瞬时功率平衡为基础

对并联型有源电力滤波器直流电容平均电压与脉动电压的变化规律进行研究

分析了它们对并联型有源电力滤波器性能的影响。为了克服这种影响

提出了在补偿电流中注入基波有功电流和增大直流侧电容量控制直流电压稳定的一种方法。仿真结果验证了所提出方法的正确性和有效性。

Abstract

To control the DC side capacitor voltage at an adequate value is an important link which guarantees the excellent compensation characteristics of Active Power Filter（APF）.The paper bases on the instantaneous power balance of shunt active power filter AC side and DC side

discusses the change rule of DC capacitor average and fluctuant voltage

analyses their influence on the performance of shunt APF.In order to overcome the influence

a control method is proposed by injecting active current in the compensation current and enlarging the capacity of DC capacitor to control the DC capacitor voltage steadily.Lastly

simulation results are presented to verify the validity of the proposed control algorithm.
