Abstract

This report describing in depth about the management process of the "Distance Protection Scheme and Coordination for Transmission Line Analysis", which has been used by Tenaga National Berhad (TNB). In fact, distance protection system responsible in separating the failure occurred within the transmission line by counting the failure difference within the transmission line. This system will act by sending the signal to the control panel, so that the electrical energy transmission might be stopped promptly if the failure occurred is kind of a transient failure. An analysis is been done in order to ensure the smooth transmission of electrical energy and the protection system used is working properly. The analysis is accomplished by using the PSCAD programmed software in order to show the comparison between the simulation and the actual condition of the distance protection operation. Simulation is being done for the transmission line between the two substations 132kV by using the distance protector hub as the protective tool. The value of the line impedance is set for distance relay. Percentage of the protection region is regarded as setting. The ultimate result will be compared with the actual condition.
