摘　　要：直流系统的控制与保护系统是云贵互联通道工程设计的重要组成部分,控制系统与保护系统的相互配合、相互作用,以确保直流输电工程的安全稳定运行。±500 kV禄劝换流站是云贵互联通道工程的首端换流站,其控制系统与保护系统在禄高肇三端直流控制保护FPT试验过程中存在异常,本文针对异常进行分析与研究,提出了优化的措施,对三端直流输电工程的安全运维有着重要意义。The control and protection system of the DC system are important parts of the design of the Yunnan-Guizhou interconnection channel project,the coordination and interaction of control system and protection system to ensure the safe and stable operation of DC transmission.The control system and the protection system cooperate and interact to ensure the safe and stable operation of the DC transmission project.The±500 kV Luquan converter station is the head converter station of the Yunnan-Guizhou interconnection channel project,and its control system and protection system are abnormal during the FPT test of the three-terminal DC control protection of Luquan-Gaopo-Zhaoqin.This paper analyzes and studies the anomalies,and proposes optimization measures,which are of great significance to the safe operation and maintenance of the three-terminal HVDC transmission project.
