摘要
提出了一种三相四线并联有源电力滤波器(APF)主电路的统一拓扑结构,建立了它的数学模型,并定义了衡量并联APF补偿性能的指标。在此基础上分析了2种电流滞环控制策略应用于三相四线并联APF时存在的本质缺陷,通过具体的仿真计算验证了所得到的结论,为改进三相四线并联APF的电流滞环控制策略提供了重要的理论依据。
This paper presents a unified topology of the three-phase four-wire shunt APF and its mathematic model. Based on these works, some shortages of hysteresis current control strategy for the three-phase four-wire shunt APF are investigated. The validity of all the conclusions is proved by simulation results. This paper offers a significant theory basis for improving compensation capability of the three-phase four-wire APF with the helps of hysteresis current control strategy.
