摘要
介绍了某电厂发电机定子接地故障情况,通过逐步逼近法对发电机定子接地整个事件过程检查分析,排除了发电机本体原因,找到了发电机出口PT故障为跳闸原因,为今后各类发电企业防止类似事件发生,为快速判断故障点及查找原因提供了借鉴参考。
Stator grounding fault in a thermal plant's generator was introduced in the paper.By analyzing stator grounding with successive approximation,we found that trip caused by PT fault.The case provided reference for finding reason.
