摘要(Abstract)：

模块化多电平换流器(modular multilevel converter,MMC)电磁暂态高效建模的难点,在于对桥臂中大量结构相同的级联子模块(sub-module,SM)进行等效的同时保证消去的节点信息都可以被精确反解。提出一种针对多类型MMC的电磁暂态通用建模和实现方法,它对传统的单端口MMC和新近出现的双端口MMC都适用。同时提出一种MMC拓扑自动识别方法,可以大幅降低模型用户在对特定拓扑建模时候的工作量,同时绝大部分模型代码都可以继承。最后,在PSCAD/EMTDC中分别以单端口和双端口MMC为例,对所介绍的等效建模算法进行了验证,结果表明所提出的算法具有很强的通用性。
