Abstract :
Analysis of fault generated traveling waves is the base to implement traveling waves based protection and fault location. However, the structure at fault point is not asymmetrical under single-phase to ground fault condition in multi-phase power system, so that traveling waves analysis method of single circuit can not be applied. The paper at first analyzes initial traveling wave at fault point generated by the fault through resistance, according to superimposed theory and using phase-to-module transformation method, then considers the fault generated traveling waves´ characteristics at the relay point. At last, EMTP is implemented to verify the correctness of analysis of single-phase-to-ground fault generated initial traveling waves
