- Abstract
Stator single-phase grounding faults of generator often occur in the production process. If the fault cannot be removed quickly,it will bring great harm to power generation equipment and power system. A novel location method for stator single-phase grounding fault of large non-salient pole generator is proposed, which can determine the location of stator single-phase grounding fault by power frequency zero-sequence voltage and power frequency voltage of fault phase. The proposed method is suitable for the generator with neutral point grounding via high resistance and the generator without grounding neutral point,and it does not rely on voltage injection type stator grounding fault protection. Because the proposed method needs less fault information,it is easy to operate and can be widely used in the field. Simulation data and actual fault cases verify the correctness of the proposed method.
