Repotencialização das redes aéreas rurais e urbanas: estudo de caso em uma propriedade rural de Dourados-MS

Abstract

Electrical energy is one of the main resources in the development of a society, which has the intensity of its usage as a point that reflects the development of a region or country. Given the importance of electricity, and knowing that its generation, in general, will not happen at the consumption point, appears the necessity of a system that will establish a trustworthy connection between these two points, which can be achieved through above the ground grid lines. With that said, a study about medium and low voltage electrical energy grid lines will be presented in this paper, focused in the elaboration of projects for this kind of system. Since big part of electricity distribution is done by an overhead transmission system, the procedures required to dimension an overhead grid system will be detailed in this paper, in order to provide the access to electrical energy and improve the distribution system to the final consumer. Finally, to better comprehend the given methodology, a project was elaborated to improve the distribution of electricity to a consumer located in Dourados-MS. In order for that to happen, it was suggested the substitution of a byphasic Rural Distribution Line of lower voltage (220/127V), to a Rural Electrical Energy Distribution Line, of medium voltage (13.8 kV), with a triphasic Converter Point of 30 kVA, voltage 13,800/220/127V. In this paper, it is possible to realize the importance of theorical knowledge of power grid systems and its structures, also the experience of the project manager is very important, especially during the first stage of the project, when data of the location where the distribution system is going to be installed is being acquired, since one simple mistake in this process might prejudice the quality of the system or even prevent the power supply to the consumer.
