| Abstract: | A system for steady state performance calculation and protection scheme analysis of internal armature winding fault in hydro generator is presented in this paper. It can deal with various internal faults of large hydro generators with different dimensions, slot and pole numbers, winding types and winding neutrals arrangement. It can also analyze protection schemes such as differential protections and give their optimum CT combinations. This system can be widely applied to analysis and protection of internal faults in armature windings of the hydro generator. |
