PROJETO DE REDE DE DISTRIBUIÇÃO DE ENERGIA ELÉTRICA PARA DIMINUIR DEC

Abstract

Frequent and prolonged power outages cause significant economic and social impacts. Companies and industries face losses due to interruption of operations, loss of data and damage to equipment, in addition to increased operating costs and preventive maintenance. Commerce and services, such as supermarkets and restaurants, suffer from inadequate food preservation and the inability to operate essential systems, such as payment systems. Educational institutions are also 2 affected, hindering classes, research and extracurricular activities. In addition, the lack of lighting increases the risk of accidents, aggravating the effects of these outages. The general objective of this work is to analyze the development of power distribution network projects, with the main focus being to develop a project that can influence the reduction of the Equivalent Duration of Interruption per Consumer Unit (DEC). The methodology involves the design phase, where key factors are analyzed, such as terrain topography, calculation of the pole's stress to determine the resistance of the pole to be allocated, dimensioning of medium and low voltage cables, load to be installed or modified, protection equipment and maneuvers to ensure a low DEC index, but mainly for the safety of the surrounding network and for those who need to maneuver or perform maintenance on the network. With the statistical data and calculations performed throughout the study, when using protection equipment (fuse switches, repeater switches, reclosers), it is possible to significantly reduce DEC indicators.
