Abstract

In this study, High Voltage Transmission Line fault location accuracy of distance relays running impedance algorithm are compared with Travelling Wave (TW) method. Line faults in 154 kV Tatvan – Muş and 154 kV Patnos-Erciş lines in Turkish Electrical Transmission System are analyzed. Real faults in both lines are simulated in MATLAB-SIMULINK. Tower configuration and conductor properties of the lines and the source impedances are included in the simulation to comply with real system. Simulations show that both single-end and double-end Wavelet Transform (WT) based TW methods have better accuracy then the distance relays computing fault location by impedance methods.
