Title

PREDICTION OF UNSYMMETRICAL FAULTS IN SMART POWER SYSTEM USING MHO RELAY CHARACTERISTICS

Abstract

This paper deals with model of Mho relay characteristics for the prediction of unsymmetrical faults in a power system using PSCAD software. Mho relay characteristics, frequency dependent phase model type transmission line is modelled and simulated using PSCAD Software. To study the performance of the relay characteristics, line to ground faults at different locations are considered. The test network used in this paper is 220kV transmission line system. The modeling is done by taking voltage and current signals at relay location and apparent impedance is calculated after extracting the fundamental component using Fast Fourier Transform block. Impedances are compared and the location of fault is predicted in the power system. A 100km long transmission line divided into 2 zones of protection is modelled in this paper.

Key Words

Mho relay, PSCAD, Unsymmetrical faults, Zone impedance, Simulation.
