Abstract

High impedance fault detection in power distribution systems has been addressed by many researchers and by the power industry worldwide. Due to the variable nature and low amplitude of the high impedance fault current, its dependable and fast detection is a challenge, which is justified by the hazards it can cause to the consumers (deaths, fire, financial losses etc). There is not a definitive solution for detecting a high impedance fault, thus any contribution to fill the gaps left by the already proposed methods is necessary and very welcome. In this context, this Master research project aims to develop a hybrid method to detect high impedance faults by using frequency-domain and time-domain techniques to extract relevant characteristics of the current and voltage waveforms associated with this kind of occurrence. To validate the method, simulated and real fault impedance data will be employed. Moreover, the method will be based in previous advances already developed by our research team.
