Method of Setting of the Self-adaptive Relay Protetction

YUAN Zhao-qiang,WU Qiang(College of Electrical Engineering and Information Science,China Three Gorges University,YiChang 443002,China)  
This paper analyses the measure that unsymmetrical three phases and zero sequence current identify unsymmetrical fault during the power swing and amending modulus of the discriminants base on self-adaptive.The count of modulus can change with the shift of the point of fault.So the delayed time can be reduced,even instantly distinguish power swing and fault.
