摘要 提出了一种基于模块化多电平换流器(Modular Multilevel Converter,MMC)拓扑的配电网静止同步补偿器(Distribution Static Synchronous Compensator,DSTATCOM)主电路,该电路无需变压器可直挂于高压系统,非常适合高电压、大容量场合的应用。分析了该电路的基本工作原理,并提出针对不平衡负载的补偿量检测以及补偿输出电流控制方法,最后通过PSCAD/EMTDC仿真验证了所提方法的有效性。 A distribution static synchronous compensators (DSTATCOM) main circuit based on Modular Multilevel Converter (MMC) is present, which can be installed in high voltage distribution system without transformer. The basic operating principle, detecting method of compensate component for unbalanced load and current control method are discussed. At last, a time-domain simulation module of MMC-DSTATCOM is implemented in PSCAD/EMTDC.
