Proposta de melhoramento da rede de distribuição de energia eléctrica de baixa tensão no Bairro de Hulene “B”

Abstract

Following the demographic growth and the consequent evolution of the consumption, the distribution network has been reinforced and modernized, in order to response to the improvement of the electricity network since in the Hulene district “B” presents to low voltage due to voltage drop problems, resulting in frequent outages. This problem is associated with long low voltage cable runs and lack of public lighting, which leads to a lack of security for residents. In the present work, the primary and secondary distribution networks will be addressed. secondary and will aim to dimension a medium voltage line with extension of 800 m to supply a 315 kVA low voltage transformer with extension of 2500 m and then calculate the number of supports and in parallel determine the amount of material to apply for the execution. The aim of this study is to determine the best possible route for both the line or for the location of supports in order to obtain low costs and high reliability. The project proposes a technical and economic solution for the improvement of the electricity distribution network in the aforementioned area. This area, currently has 4 PTs operating above their nominal regimes.
