Redimensionamento de um posto de transformação como estratégia para melhorar a qualidade de energia eléctrica no Bairro das Mahotas:caso de estudo do PT136 - Cidade de Maputo

Abstract

The present work refers to the dimensioning project of an electricity transformation station to meet the population demand of the residents of the Mahotas neighborhood in the city of Maputo, the Transformation Station 136 is located at Rua de Cúpula. This project arises within the scope of complaints about overloading the current transformer station, which is in the order of 28.88%, as a result of the increase in load. The purpose of this project is to dimension the new transformer station as well as the two outputs to supply part of the current transformer station's load. The study was carried out based on the bibliographic method - documentary, direct and participatory observation on site, as well as the use of the descriptive method. During the execution of the work, the load survey was carried out, evaluation of the extension of the low voltage network and finally, as a result, a 160kVA transformer station with two low voltage network sub-feeders will be added to feed a load part of the current transformation station. Thus, the system will consist of two transformers, the current one of 315kVA and the new one of 160kVA, dividing the load and creating a power reserve in the two transformers, it will be fed with an 11kv line called Estádio Nacional. The work is budgeted at 1,468,302.857MZN for the acquisition of the system, as well as a part for the payment of the technical staff for the assembly of the PT. (TRADUÇÃO NOSSA )
