An Alternative Approach for Location of Transmission Line Faults based on Artificial Neural Network

Abstract

This paper describes the application of an artificial neural network (ANN) for location of transmission line faults. Three phase post fault samples of currents and voltages taken at one end of transmission line are used as inputs. Simulation studies have been carried out extensively on two power system models : one in which transmission line is fed from one end and the other in which transmission line is fed from both ends.The models are subjected to different types of faults at different operating conditions for variations in fault location, fault inception angle and fault point resistance. The results presented confirm the feasibility of the proposed scheme.
