阿萨汉水电站注入式定子接地保护应用探析

Research on application of injection type stator grounding protection in Asahan Hydropower Station

介绍了印度尼西亚阿萨汉一级水电站注入式定子接地保护原理构成,并对该电站自投运以来几起定子接地保护动作行为进行分析,提出了注入式定子接地保护在实际应用中值得探讨和关注的问题,着重阐述了注入式定子接地保护在设计施工和运行中应注意的事项。

The principle and the composition of the injection type stator grounding protection of Asahan First Stage Hydropower Station in Indonesia were introduced. The stator grounding protection of the hydropower station tripped several times since the hydropower station was put into operation. The protection tripping behavior was analyzed. The problems,which deserve research and attention in practical application of the injection type stator grounding protection,were pointed out,and the matters needing attention in design,construction and operation of the injection type stator grounding protection were expounded emphatically.
