摘要
柴达木—拉萨直流系统在试运行期间发生谐波保护动作,导致直流系统闭锁事故,通过分析直流谐波保护动作原因,提出处理措施,消除100Hz保护动作引起的直流系统单双极闭锁问题,保证了柴达木—拉萨直流系统安全稳定运行。
The DC system of Chaidamu to Lhasa happened harmonic protection action caused DC system lockout accident, analyzed the reason and proposed treatment measures, to eliminate 100 Hz protection action causing the DC system single and double pole lockout issues, and ensure Chaidamu to Lhasa DC system＇ s safe and stable operation.
