Melhoramento da rede de distribuição de energia eléctrica de média tensão no bairro de Maxaquene D

Abstract

This article presents a recommendation for a medium-voltage electricity distribution network in the Maxaquene D neighbourhood, Maputo city, as part of the improvement of the existing network, with the goal of satisfying the needs of the neighbourhood's residents. The project was dimensioned based on the knowledge acquired during the Electrical Engineering course at UEM and the learning acquired during the professional internship at EDM. In line with demographic growth and the consequent increase in consumption, the distribution network has been reinforced and modernised. This work will focus on the primary distribution network and will aim to dimension a medium-voltage line with a length of 200 metres to feed a 250kVA transformer and subsequently determine all the parameters and technical-financial aspects for carrying out the project. The aim of this study is to determine the best possible route, both for the line and for the location of the PT and supports, in order to achieve low costs and high reliability. The project proposes a technical and economic solution for improving the electricity distribution network in the aforementioned area, which currently has a network operating above its nominal capacity. An illustration of the positions and installations of almost all the elements of the new network is shown on the map of the neighbourhood's new network, presented in Annex 1 of this work.
