Travelling wave fault location algorithm in HV lines — Simulation test results for arc and high impedance faults

This paper presents simulation test results of the travelling wave fault location algorithm used in high voltage (HV) lines. The algorithm based on a wavelet transform, is tested for different fault types, including high impedance faults (HIF) and arc faults. Automatic test procedure (with use of PSCAD/EMTDC, Matlab) enabled to perform vast number of simulations for each testing scheme. Simulation results from a PSCAD/EMTDC model are compared with EMTP-RV results in order to confirm the correctness of the testing scheme.
