| 摘要: |
| 主要介绍100MW及以上发电机保护在1998～2002年5年里的运行情况，重点对发电机保护正确动作率偏低的保护，如差动保护、匝间保护、定子接地保护、负序电流保护不正确动作情况，通过实例进行分析，总结存在的问题，最后对发电机保护不正确动作情况进行了责任分析。希望通过对近5年发电机保护运行情况的总结，进一步交流信息、经验，为提高发电机保护运行水平，完善发电机保护的性能，提高产品质量，改进工作，为电力系统安全稳定运行创造条件。 |

| Abstract: |
| The operation situation of 100 MW and above generator protection from 1998 to 2002 is introduced,focusing on the protections of low correct operation rate,such as differential pro-tection,inter-turn protection,stator earthing protection and negative sequence current protection. The existing problems are summarized by example analysis and the responsibility analysis is carried out for the generator incorrect operations. It is aimed to improve the performance and operational level of generator protection by exchanging the experience and information. |
