Transmission System On –Line Fault Location Using ArtificialNeural Network

Abstract

In this work, protection systems for overhead transmission lines areinvestigated and an efficient technique for on –line fault location based onArtificial Neural Network(ANN ) is suggested. First, Studying and investigatingthe power transmission lines short circuit modeling and analysis, and thendeveloping a MATLAB programs to calculate fault currents and voltages fordifferent fault types depending on the location of the fault in the transmission lineand finding the location of this fault. The proposed technique for the faultlocation is the two -end data technique. The pre-fault data plus the fault dataconstruct a training set for the neural network programs which contain two types,one for fault detection and classification, and the other for the fault location. Then,these programs are applied on the Iraqi super grid (400 kV).
