发电机励磁过负荷保护动作跳闸事故分析及处理

Analysis and Treatment of the Generator Excitation Overload Protection Tripping Accident

通过对发电机励磁绕组过负荷(反时限)保护动作跳机的事故分析,找出了事故原因和问题所在,进而对励磁调节器的升级改进,发电机组的安全稳定运行得以保证。

This paper analyzes the generator excitation winding load （inverse time） the protection action of tripping accident, to find the cause of the accident and where the problem lies, and thus improve the upgrade of the excitation regulator, safe and stable operation of the generator set can be guaranteed.
