Abstract

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).
