Abstract:

Abstract:This paper introduced protection principle of injection type of rotor earth fault protection equipment generated by additional power and hazard of rotor earthing.Based on an earth fault of main exciter rotor of a set of separate excitation system,this paper proposed a process of fault handling and analyzed the cause of this fault.At the same time pointed out that the system failure cannot be detected if rotor earth fault protection equipment is under specific operation mode.A reasonable judgment means of assistant measuring is provided.
