摘要(Abstract)：

对无刷励磁系统励磁调节器ABB Unitrol 5000投运初期出现的一起转子接地报警异常现象进行了分析,指出发生接地报警的原因是调试阶段接线失误所致,应加强对转子接地保护接地点的检查。
Through the analysis on a case of abnormal phenomenon of rotor grounding alarm that occurred during the initial operation stage of the brushless excitation system excitation regulator ABB Unitrol 5000,this paper identifies the alarm reason as the connection fault during the commissioning and it should improve the inspection of the rotor grounding protection grounding point.
