Abstract

An MV fault location technique based exclusively on low voltage measurements in the distribution network is presented in this paper. The technique is based on sequence component analysis of the voltage measurements in order to characterise the LV voltage during MV faults. The accuracy of the technique is evaluated using a DigSILENT PowerFactory model where various fault conditions have been studied including the impact of distributed generation connection on the network voltage profile. The model represents the Power Networks Demonstration Centre’s (PNDC) MV and LV test network. This is to facilitate the validation of the model in the future implementing physical fault testing and measurements using the PNDC network.
