Projecto de expansão de uma rede de distribuição de energia eléctrica no bairro de Boquisso “B”, Maputo

Abstract

This report is part of the scope of obtaining a degree in Electrical Engineering at the Eduardo Mondlane University, focusing on giving a description of the project for the expansion of an electricity distribution network, carried out during the three-month internship at EDM. Given that electricity runs through a complex system, which can generally be described in four stages: generation, transmission/transport, distribution and consumption, the Medium Voltage and Low Voltage Networks are part of the distribution of electrical energy. The expansion of an electricity distribution network in the neighborhood of Boquisso “B” was projected, restricting it to block 12, where based on the area criterion, a predictable power of 729 kVA was estimated, with this , dimensioned 6 transformers with individual capacity of 160 kVA, and these will have their power through three medium voltage lines with a total length of 4 km, where in turn, these will have a derivation at three points of existing lines that delimit areas close to the intervention zone using switch-disconnectors at each derivation point and applying the ACSR CONDUCTOR 24.43 mm² - SQUIRREL cable. The sized PTs will have the function of supplying energy to a 5.6 km low voltage distribution network through APAR INDIA 0,6/1kV ALUMINIUM XLPE ABC CABLE 3x70+1x54,6+1x25 𝑚𝑚2, cable, with general protection in each QGBT of 200A, partial 125A to favor 243 single family houses.
