Projeto de rede de distribuição de energia elétrica para atendimento a loteamento residencial

Abstract

Urban expansion and the development of new residential subdivisions require appropriate technical solutions to ensure a safe and continuous supply of electric power. In this context, this work presents the design of an overhead electric distribution network in medium and low voltage to serve a residential subdivision located in the municipality of Araruna, in the state of Paraná, Brazil. The project was developed based on the technical standards of the local utility company COPEL, along with national regulations. For the design, real data from the subdivision's civil layout, the existing nearby electrical infrastructure, and the area's topography were taken into account. The electrical network sizing involved the definition of supply circuits, transformer locations, selection of conductors, support structures, and the protection and grounding system. The subdivision comprises 497 lots distributed across 32 blocks and will be supplied by 12 three-phase 75 kVA transformers, connected through a branch from an existing 13.8 kV network. Additionally, a 224-meter section of a 34.5 kV line was relocated and reconstructed using insulated conductors, in accordance with the new urban layout. As a result, a complete project was developed, supported by specialized design software and ready for implementation, including a descriptive report and material specification. The proposal fully meets the established technical standards and represents a practical contribution to electrical engineers and professionals involved in planning and executing distribution networks for residential developments.
