摘要
介绍了某发电公司发生的一起发电机三次谐波定子接地保护动作事件,从设计缺陷、关闭步骤有误、内漏缺陷、经验反馈等方面分析了事件原因,并提出了一系列有效的防范措施,可为同类型机组的类似情况提供借鉴。
An accident of third harmonic stator grounding protection action in generator is introduced, which is happened in the operating process of a power plant. The cause of fault is analyzed in respect to the design flaw, incorrect closing procedure, inner leakage defect, experience feekback, etc. A series of effective preventive measures are proposed, in order to provide reference for similar events of the same type of units.
