摘要

文章以鹅城换流站阀水冷系统为例

通过分析主循环回路中电动阀的控制逻辑

指出其中存在导致直流系统闭锁的隐患

提出的应对措施避免因电动阀门故障导致直流系统闭锁

保证了换流站的安全稳定运行。

Abstract

Taking the example of the valve cooling system at Echeng converter station

by analyzing the control logic of motor valve in the main circulating loop

the hidden dangers that may cause DC system block are pointed out in the paper.Countermeasures are presented to avoid potential DC system block due to motor valve faults and ensure the safe operation of the converter station. Recommendations on the future design of the valve cooling system for the new converter station are given and can be used as reference for other converter stations.
