摘要
Abstract
This paper focuses on the key position of small and medium-sized hydroelectric generators in the power system and the effective handling and auxiliary decision-making techniques for single-phase grounding faults in the stator windings.It analyzes the types,causes,and effects of single-phase grounding faults in stator windings on generator operation,and proposes the construction of an auxiliary decision-making system for sta-tor grounding fault detection in small and medium-sized hydroelectric generator units.The paper elaborates on the overall framework of auxiliary decision-making methods.Through practical examples,it has been proven that the system can significantly improve the timeliness and accuracy of fault diagnosis,reduce human errors,and provide strong support for the stable operation of small and medium-sized hydroelectric generating units.In the future,system algorithms and interface design will be further optimized to adapt to more complex fault situations and higher operational requirements of the power system.关键词
