Transmission system on –line fault location using artificialneural network

Abstract EN

In this work, protection systems for overhead transmission lines are investigated and an efficient technique for on–line fault location based on Artificial Neural Network (ANN ) is suggested.

First, studying and investigating the power transmission lines short circuit modeling and analysis, and then developing a MATLAB programs to calculate fault currents and voltages for different fault types depending on the location of the fault in the transmission line and finding the location of this fault.

The proposed technique for the fault location is the two -end data technique.

The pre-fault data plus the fault data construct 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).
