| Abstract: | For phase-to-phase and turn-to-turn S/C, analysis and calculation added up to 11490 faults have been made for Three Gorges hydraulic power plant generator No.1, combined with simple element transverse differential protection, split-phase transverse differential protection, incomplete and complete longitudinal differential protection. Based on sensitivity calculation, the main protection scheme of internal faults for this generator is proposed in this paper. |
