摘要:
提出一种三相四线并联有源电力滤波器(APF)主电路统一的拓扑结构,三桥臂电容中分拓扑和四桥臂拓扑都是该拓扑结构的一个特例。建立了三相四线并联APF统一的数学模型和性能评价指标体系。在此基础上,文中分析了三相四线并联APF应用电流滞环控制策略时的性能,得出了各桥臂输出电流相互干扰的机理,并对两种电流滞环控制进行了比较,通过具体的仿真计算验证了所得到的结论。该文的理论推导和所得结论为改善三相四线并联APF应用电流滞环控制时的性能提供了较好的理论基础。

Abstract:
This paper presents a unified topology of the main circuit of the three-phase four-wire shunt APF. The four-leg topology and the three-leg split-capacitor topology are special forms of this topology. The mathematic model and performance evaluation index system were built for this topology. Based on these works, some shortages of current hysteresis control strategy applied to the three-phase four-wire shunt APF were achieved. All the conclusions are proved by simulation results. This paper offers a better theory basis for improving compensation capability of the three-phase four-wire APF controlled by hysteresis current control strategy.
