Location Algorithm

This paper focused on studying an algorithm of earth fault location in the medium voltage distribution network. In power system network, most of the earth fault occurs is a single line to ground fault. A medium voltage distribution network with resistance earthing at the main substation and an earth fault attached along the distribution network is modeled in ATP Draw. The generated earth fault is simulated, and the voltage and current signal produced is recorded. The earth fault location algorithm is simulated and tested in MATLAB. The accuracy of the earth fault location algorithm is tested at several locations and fault resistances. A possible correction technique is explained to minimize the error. The results show an improvement fault location distance estimation with minimum error.

The Impact

The penetration of renewable energies of Direct Current (DC) to the Distribution Network of Direct Current of Medium Voltage (MVDC) is already a reality. Therefore, extensive planning is required for its location in the electrical network. The implementation of this energy brings great advantages to the system since it contributes to the reduction of losses, improvement of the voltage profile, greater reliability in the system since there is generation of the photovoltaic system installed and of the distribution company. This article was carried out through a bibliographic review of the bases IEEE Xplore, Science Direct, Taylor & Francis and related academic knowledge, identifying several positive and negative aspects of this new reality of renewable energy, in the same way it was analyzed the Energy Storage System (BESS) and the impact of Electric Vehicles (EV) on distribution networks.
