摘　　要：云广±800kV直流输电工程由于采用了2个12脉动阀组串联的接线形式而使得使得其控制系统比±500kV常规直流更为复杂。在全面总结和分析了云广±800kV直流输电工程控制系统的功能的基础上,指出其大多数功能与±500kV常规直流的基本相同;主要区别在于增加了单个阀组的自动投退控制,适应直流孤岛方式的特殊控制,以及与SVC之间的协调控制。The control system of Yunnan-Guangdong ± 800 kV DC transmission project is more complex than the conventional±500 kV DC system as the project adopts a series Dual 12-Pulse valve groups connection structure. This paper summarizes and analyzes the functions of Yunnan - Guangdong ± 800 kV DC control system, and concludes that the control system has the basic functions of the ± 500 kV system, and the main difference between them is that the ± 800 kV system has exclusively the block and deblock control for the multiple valves, and the special control for islanding operation mode, as well as the cooperating control with SVC.
