ANÁLISE DA VIABILIDADE TÉCNICA E ECONÔMICA PARA INSTALAÇÃO DE UM GERADOR FOTOVOLTAICO CONECTADO A REDE PARA INDÚSTRIA ATENDIDA EM MÉDIA TENSÃO

Abstract

The present work has the main objective of the project and the economic viability of the implantation of a photovoltaic generator connected to the network of the distributor in the distributed generation model, being the chosen location an industry located in Varginha / MG served by group A and High voltage) of the local concessionaire meeting the requirements of Normative Resolution 482/2012 and 687/2015 of the National Electric Energy Agency (ANEEL). For the design of the system, it was first analyzed the location available for generator installation and technical information such as roof type or soil type, inclination, orientation, type of power supply, utility entrance branch and solar radiation on site. As for the sizing of the grid-connected photovoltaic system, the annual expenditure on energy consumed at peak hours (HP) and on off-peak hours (HFP) was initially collected, and the generators were then analyzed for the two charging schedules. financial feasibility analysis of the system was used the simple financial payback method where it was considered three bases: Generation of electric energy in the useful life, an estimate; Initial cost and lifetime cost; Estimation of cost of electricity in the useful life period. In the design of the photovoltaic generator, all the electrical parameters and efficiency of the system were considered, as well as the electrical losses that influence the design. The tariffs at peak and off-peak hours were individually evaluated and projected in the same way, resulting in 159,46 kWp systems with 476, 335Wp photovoltaic panels, where this value can not be exceeded due to contracted demand, but taking full account of the local load and generating a significant savings in electric energy expenses with the financial analysis payback of 6.4 years.
