| 摘 要： | 二滩水电站水轮发电机组从通用电气加拿大公司引进,发变组保护由 ABB公司提供,在国内较早采用了发电机中性点经单相变压器接地方式,并与定子绕组单相接地保护相配合,迄今运行良好.根据二滩水电站实际情况对发电机中性点经单相变压器接地方式及定子绕组单相接地保护配置详细分析研究可供参考.

| Abstract: | As the greatest hydropower station of china last century, the Generator of Ertan Hydropower Plant was supplied with the branch of GE Company in Canada. The protector of it was supplied with ABB Company. Generator neutral grounding used the single-phase transformer between generator neutral and ground early in domestic., which coordinated with the stator winding protector of single-phase grounding. It has been running well till today.The thesis analyse and reseach in Generator neutral grounding by the single-phase transformer and the stator winding protector of single-phase grounding. |
