中文摘要:

云广特高压直流控制保护系统通过冗余配置的测量总线获取现场测量的数据,实现特高压直流系统稳定运行。本文介绍了云广直流工程测量系统的配置,分析测量总线故障识别方法以及故障情况下的切换逻辑,结合运行中出现的问题,指出故障识别设计中的缺陷,提出了改进方法并在现场得到应用。

英文摘要:

The data on-site is transmitted to the control and protection systems by redundant configured measurement bus in Yunnan – Guangdong ±800kV DC transmission project, to achieve the stable operation of the UHVDC system. This paper describes the configuration,fault identification and switching logic of measurement bus.Based on the problem occurred during operation,pointing out the defect of design in fault identification.At last, improvement proposal is given,and the proposal has been applied in yunnan-guangdong UHVDC system on site.
