Abstract
Fault location and isolation are important in case of any transmission line to make a reduction in the outage time and fast restoration of the transmission system. Various methods of fault location using voltage samples and current samples have been used in practice but with the development of Phasor Measurement Unit (PMU) many new method have been designed. The two terminal method of fault location is employed to calculate the fault location as the present communication technology used to access of data from two terminal. In the above method fault impedance does not affects the location. The main aim of this project paper is to calculate the exact fault location and compare the result of calculated fault location and its error with and without frequency variations. For the study, Electromagnetic Transient Program (EMTP) Reference Models for Transmission Line Relay Testing Final-9/9/2005 is considered. The deception of the selected method is analyzed and evaluated by simulating the network in PSCAD under both steady state and transient conditions after that result are transferred into MATLAB Simulink for the further processing and result are obtained.
