| Abstract: | 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. |
