摘要
以某电厂一起发电机组三次谐波定子接地保护动作为例,介绍了三次谐波定子接地保护的逻辑原理,描述了发电机组发生故障时的现象,通过分析故障前后的运行数据,判断了故障点,并及时消除了机组隐患。
In this article, it is introduced that a case of three-harmonic stator grounding protection action in a power plant. The logic principle of three-harmonic stator grounding prection is introduced , the generator failure phenomenon is described, and the three-harmonic stator grounding protection logic principles are given . Through the analysis of the fault data, the failure place is determined and eliminated .
