Análise técnica, econômica e otimização em projetos elétricos de redes compactas de distribuição para um loteamento residencial

Abstract

The growing demand for efficiency and sustainability in energy distribution highlights the relevance of compact networks. In this context, this work addresses a technical, economic and optimization analysis of electrical projects for compact distribution networks for residential subdivisions. The main objective was to investigate the influence of strategic choices, such as transformer capacity and load arrangement, on the economic results of projects. To achieve this objective, four projects (A, B, C and D) were compared, using an automated spreadsheet that enabled sizing and listing of materials. Projects A and B were developed with seven 112.5 kVA transformers, while projects C and D used four 225 kVA transformers. Furthermore, the loads were positioned on the main avenues in projects A and C, and on the central avenues in projects B and D. The results revealed that the choice of transformers with greater capacity, evidenced in projects C and D, contributed significantly to the reduction of costs. The choice of network topology also played a crucial role in economic efficiency. Projects with loads on main avenues allowed the maintenance of smaller section conductors, optimizing costs and materials. This study not only consolidated the results obtained, but also highlighted the importance of strategic choices in the development of electrical projects for residential subdivisions.
