Estudo de caso: projeto e análise ao impacto da eletrificação rural no desenvolvimento de uma propriedade na região de Bagé/RS

Abstract

The following paper aims to offer a great benefit by the cost of electric energy relative to a rural property and to analyze scenarios which may be implanted in the future, emphasizing the economic feasibility, energetic efficiency and socioeconomic development. The present case study was held in a rural property in the region of Bagé, in which the choice of the location was based on the subject’s presentation in rural class entities, where there was a search for a place with little energy time or didn’t yet have it. A visit in the property was made to gather data about the situation in which the land was, so it was possible to verify that the acreage doesn’t have access to electric energy and, furthermore, there are a lot of contributors, difficulting the life quality of the same and for generating electric energy a diesel power generator is used. Based on these data a methodology for approaching the listed problems was elaborated. In the lighting project the NBR 8995-1:2013 was used, where it deals with lighting standards. In the residential electrical project, NBR 5410:2004 was used, which establishes the minimum conditions that a low-voltage electrical installation must include. In the single phase and three-phase project, the norms of the concessionaire in the region were used, and the three-phase network was designed to meet a central pivot load, as an irrigation method. The dimensioning of the photovoltaic solar system was also carried out, in which the average solar irradiation of the property and the average energy consumption of the place were used. It was found that there was a considerable reduction in the cost of energy, using the solar system and for the single-phase and three-phase projects, the implementation costs were obtained, and only with the single-phase project there was a high reduction in cost compared to the situation current and in the three-phase project with the use of the center pivot, it proved to be feasible from the analysis of the net present value.
