摘　　要：结合当前运行换流站极控系统间通讯、站间通讯结构和原理,分析某换流站发生的1起极控系统间通讯故障及1起极控系统站间通讯故障原因,指出极控系统间通讯、极控系统站间通讯均存在非完全冗余设计缺陷,并在此基础上提出相应的优化措施,实现极控系统间及站间通讯的完全冗余设计。Combining the communication between the pole control systems of the current converter station and the structure and principle of the inter-station communication,analyze a communication failure between pole control systems and a pole control system inter-station communication failure that occurred in a converter station,and point out the pole control system There are defects in the incomplete redundancy design in the communication between the pole control system and the communication between the pole control system stations.On this basis,corresponding optimization measures are proposed to realize the completely redundant design of the pole control system and the inter-station communication.
