Abstract

Accurate fault detection and location on high-voltage transmission lines is critical to power system reliability, rapid service restoration, and protection-system coordination. This paper presents a simulation-based comparative study of two established fault-location methodologies—the Travelling Wave Method (TWM) and the Wavelet Transform Method (WTM)—applied to a 25kV, 200km transmission line modelled in MATLAB/Simulink. Four symmetrical and unsymmetrical fault types are analysed: single line-to-ground (LG), double line (LL), double line-to-ground (LLG), and triple line (LLL). Faults are injected at four locations (50km, 100km, 150km, and 180km) with a switching time of 0.04s and fault resistance of 0.001Ω. Voltage and current waveforms under each fault condition are captured and analysed, and predicted fault distances are compared against actual distances to compute absolute location error. Results show that the Travelling Wave Method achieves a mean absolute error of 1.10km (maximum 1.66km) while the Wavelet Method yields a mean absolute error of 1.57km (maximum 2.35km), demonstrating a 30% accuracy advantage of TWM over WTM at the test distances considered. The study provides a structured methodological comparison and quantitative error analysis intended to inform protection-engineer selection between these two paradigms for field deployment.
