A cable fault location method based on power balance theory

This paper presents a new cable fault location method based on power balance theory.According to the distributed parameter model,the proposed algorithm utilizes searching and iteration methods to locate the fault point.Only using data of single terminal,the algorithm can eliminate the influence of the fault resistances and it needn't resolve the complicated equation of long line and can be realized easily.So it has a very practical value.The simulation result of EMTP shows that it has high accuracy.
