摘要
简单介绍了三峡左岸电站 14台发变组内部故障主保护及TA配置方案 ,对清华大学关于三峡发电机内部故障主保护及TA配置方案所做的工作进行了总结 ,从主保护配置方案的灵敏性、发电机中性点侧TA的数目等方面对两种保护方案进行了对比 ,为三峡工程今后的工作提供借鉴。
Firstly,the main protection scheme of internal fault and disposition of current transformer are simply introduced for the generator transformer in Three Gorges Left Bank Power Station.Then,the research work of Tsinghua University in these aspects in reported.Finally,two kinds of protection scheme are compared from the view of the sensitivity of the main protection scheme and the number of current transformers near neutral point of the generator.Those works can be used as reference for the future work in Three Gorges Power Station.
