模块化多电平换流器（MMC）是一种新型的开关模式换流器拓扑结构，具有应用于高压直流输电的潜力。本文主要介绍了MMC VSC-HVDC控制与保护系统的层次结构、功能组成和硬件配置。提出了基于系统控制器（SC）、阀座控制器（VBC）和子模块控制器（SMC）的C&P系统总体结构。介绍了动态仿真系统和上海南汇VSC-HVDC示范工程的实验结果，验证了C&P系统在稳态和暂态条件下的良好性能，适合在实际VSCHVDC工程中应用。（6页）
The modular multilevel converter (MMC) is a newly introduced switch-mode converter topology with the potential for high-voltage direct current (HVDC) transmission applications. This paper mainly focuses on the hierarchical structure, functional components and hardware configuration of the control and the protection (C&P) system for MMC VSC-HVDC. The overall structure of (C&P) system based on design and realization of system controller(SC), valve base controller (VBC) and sub-module controller (SMC) are proposed. The experimental results are introduced with the dynamic imitation system and Shanghai Nanhui VSC-HVDC demonstration project, which validates the good performance of proposed C&P system both at steady and transient conditions so as to suitable application in practical VSCHVDC project.
