摘要
某风电场220kV变电站发生一起直流系统绝缘异常导致的220kV断路器跳闸,跳闸后断路器未重合闸,此次事故剖析了具有直流系统引起跳闸的故障特征。进而从发挥运行值班人员和处理人员的主观能动性、提升设备运维综合化水平,对未来如何防范和缓解此类故障的影响提出了建议。
A 220kV circuit breaker trip occurred in a 220kV substation of a wind farm,which was caused by abnormal insulation of the DC system.The circuit breaker did not re-close after tripping.This accident analyzed the fault characteristics of tripping caused by the DC system.In this paper,the author gives some suggestions on how to prevent and alleviate the impact of such faults in the future by giving full play to the subjective initiative of operation personnel and processing personnel and improving the integration level of equipment operation and maintenance.
