Improving the Impedance Based Fault Location Method in Distribution Network Considering the Distributed Generation Unit

Ehsan Gord; Rahman Dashti

In this paper an improved impedance based fault location method is proposed. In this method, online fault locating is performed using voltage and current information at the beginning of the feeder. Determining precise fault location in a short time increases reliability and efficiency of the system. The proposed method utilizes information about main component of voltage and current at the beginning of the feeder and distributed generation unit (DGU) in order to precisely locate different faults in acceptable time. To evaluate precision and accuracy of the proposed method a 13-node is simulated and tested using MATLAB.
