Localisation de défauts monophasés dans les réseaux de distribution à neutre compensé

Abstract : The distribution system neutral point grounding by a compensation coil reduces the fault current due to a single phase fault. which ÎS the most fréquent fault type in practice. fhis means improves the supply quality, however, it makes tauli détection and local i diffieuh fhi thesis deals with fault location of low résistive self-extinguishing or permanent earth faults in radial, neutral compensated Systems. Transient fault phenomena are studied and a new fault location approach is developed. The approach is based on the exploitation of a chaiaeterisric résonance frequency of signais measured in the HV/MV ration. An algorithm has been created, developed and tested. It is validated with po system simulations and with measured fault data of real faults. The influence of différent parameters on the algorithm accuracy is examined and explairsed.
