摘要
文章主要针对李家峡水力发电厂发电机定子绕组中性点的接地方式,分析这种接地方式的特点,并结合定子一点接地保护,提出保护存在的问题,并予以计算分析,经改进定子接地保护后,有利于机组和系统的稳定运行。
The paper is mainly analyzed the earthing character based on the neutral earthing of turbine stator Winding combined one point earthing of stator winding, provided the existing problem. After carefully analysis and calculation, the improved earthing protection is stable for the operation of the turbine and the system.
