摘要(Abstract)：

MMC(模块化多电平换流器)子模块级联数量是MMC工程的主要参数,也是工程设计的重要内容之一。基于杭州江东新城智能柔性直流配电网示范工程的实际需要,对SNOP(柔性多状态开关)三端MMC桥臂子模块级联数量进行了工程设计,提出了MMC桥臂子模块数量设计原则,针对全桥型MMC直流侧电压与交流侧电压不匹配的情况,提出了全桥型MMC桥臂子模块数量的设计方法。采用所提设计方法的示范工程已顺利投运,进一步验证了该方法的有效性。
The number of sub-modules is the main parameter of modular multilevel converter(MMC), and it is also one of the important contents of engineering design. Based on the actual needs of Hangzhou Jiangdong New City intelligent flexible DC distribution network demonstration project, the cascading number of bridge arm sub-module of three-terminal MMC belonging to soft normally open point(SNOP) has been carried out for engineering design. The design principle of the number of MMC bridge arm sub-modules is proposed. For the case where the DC-side voltage of full-bridge modular multilevel converter(FBMMC) does not match the voltage on the AC side, the design method of the number of FBMMC bridge arm sub-modules is proposed. The demonstration project using the proposed design method is successfully put into operation, which further validates the effectiveness of the proposed method.
