| 摘 要： | 为实现企业配电网低成本大容量连续无功补偿,抑制电压闪变,提出基于TSC(晶闸管投切并联电容器)与DSTATCOM(配电网静止无功补偿器)的混合型动态无功补偿系统。DSTATCOM连续子系统及TSC离散子系统构成的混杂控制系统,采用基于专家决策的三层混杂控制方法,协调控制TSC电容器组的分级投切及DSTATCOM的动态连续补偿,充分利用了各自的优势,引入模糊控制自动调整PI参数改善了系统动、静态性能。仿真分析及实验结果表明了该补偿器的优越性及所提控制方法的有效性。

| Abstract: | In order to realize low cost and large capacity continuous var compensation of enterprise distribution network and inhibit voltage flicker,hybrid var compensation system basedon thyristor smitched capacitor-distribute static compensator(TSC-DSTATCOM),was put forward.Towards this hybrid system,which consists of the continuous time subsystem DSTATCOM and the discrete subsystem TSC,three-layer hybrid control based on expert decision-making was proposed.In the control system,fuzzy control was introduced to impr... |
