Paper Title:
Study of Earth-Fault Location Method for Distribution Network Based on Transient Signal
  Abstract

According to the generating process and propagation characteristics of earth-fault transient signal, an earth-fault location method for distribution network based on transient signal is presented. In the method, in order to change line characteristic impedance, a resonant filter circuit is paralleled in line segment border, so that it could cause transient current energy differences in feature frequency band on both sides of detection device. The location method achieves earth-fault area location through comparing transient current energy and energy attenuation coefficient in feature frequency band. The simulation test result shows that the method isn't influenced by distribution system grounded style, operation style and other factors and which could detect the earth-fault area rapidly and reliably in distribution network and has a high project application value.
