Abstract

Fast localization of earth faults in medium voltage grids is required in order to avoid subsequent faults and to quickly restore the normal grid operation. This paper builds upon an approach to localize earth faults by signature matching of high-resolution voltage measurements from the primary substation. The signatures are generated from a simulation model, for which in practice not all parameters are accurately known. Therefore, it is necessary to understand the impact of deviations of these parameters on the signature comparison in the localization approach. This paper presents an approach for performing such sensitivity analysis and shows the results using simulations of a realistic small medium voltage grid.
