Ravichandiran Journal on Software Engineering 2230 – 7168 2 1 24 29 neural network, fault classification, training patterns, Matlab simulation model This paper presents a neural network (NN) based method for fault classification with its clearance time, in a power system. A new method of generating the training data is proposed which has the advantage that the total number of fault simulations needed to generate the training patterns is less than that required by the conventional training method. The performance of the proposed method is investigated using the Matlab simulation model of a simple HVDC system. July - September 2007 Copyright © 2007 i-manager publications.
