ANN Based Fault Location in Electrical Distribution System

An Artificial Neural Network based fault location algorithm for distribution feeders is presented in this paper. The principle of algorithm is quite simple and it use only phasor ofvoltage and current measured at the substation, but it can estimate the location of fault with very good resolution. Firstphasor of voltage and current will be calculated and then according the type of fault, the trained ANN estimates the fault location. According to the different types of fault, ٣ differentANN’s will be used for fault location estimation. The simulations were done on IEEE ٣٤ feeder test system and the results showthat ANN’s can estimate the fault location with a good resolution for a wide range of fault resistance.
