| Abstract: | At present, the generators of Three Gorges Left Power Station are decided to be imported from foeign cmpany. The reasonable main protection scheme for them has been decided. Based on fault simulation data of one of those generators, and the possible changes of protectioon for domestic generators to be used in the future, this paper presents the main protection scheme for generators of other large-sized hydroelectric power station in China. The scheme includes the transverse differential protection, the directional relay action on negative sequence power of fault component and the incomplete differential protection. |
