Abstract
Electricity is a significant aspect of our daily lives. social activities and industries heavily
depend on electricity to function. Transmission line protection is an essential issue in
power system engineering because 85-87% of power system faults occur in transmission
lines. Proper detection of various faults which do occur on transmission lines is very
important. This project presents an impedance technique to detect and classify the
different shunt faults on transmission lines for quick and reliable protection schemes.
Discrimination among different types of faults on the transmission lines is achieved by
applying evolutionary programming tools. MATLAB software is used to simulate
operating and fault conditions on high voltage transmission line, namely single phase to
ground fault, line to line fault, double line to ground and three-phase short circuit fault.
These faults are isolated from the system using a designed impedance relay and the
distance of the fault is calculated and provided. This research project successfully
designed a functional and cost effective fault detection prototype and its simulation was
also successful.
