摘　　要：介绍了MMC-HVDC输电系统拓扑结构,针对MMC独特的结构特点和运行特性,研究了一种基于MMC的轻型高压直流输电系统的主从式架构的控制装置。该控制装置不仅能满足MMC系统对于控制算法、数据采集、脉冲分配的需要,而且具有在线配置模式、图形化显示、使用光纤总数少、子模块控制器的智能型和独立性高等优点,同时有效解决了系统上电初始化问题。对于MMC控制装置的通信问题,设计了DMA通信方式和基于FPGA的光纤通信,实现了三级控制器间的高速通信。The topology of the MMC-HVDC transmission system was presented. As to the special structural and operating characteristics of MMC, a master-slave control device of light HVDC transmission system based on MMC was designed. The control device could not only meet the need of the MMC system for control algorithms, data acquisition and pulse distribution, but also had the advantages of online configuration mode, graphic display, less fiber, high intelligence and independence of sub module controller, etc, resolving the MMC system initialization problem.For the communication problem of the MMC controll device,the DMA communication and the fiber communication based on FPGA were designed, realizing the high-speed communication between the three-level controllers.
