Resumo
Este trabalho tem como objetivo apresentar um arranjo para geração de energia elétrica a partir de
fontes renováveis, neste caso uma matriz de geração solar com capacidade maior do que 60 MWh/ ano.
O sistema fotogerador para tal análise será considerado na localidade da UNESP campus de São João
da Boa Vista e será conectado à rede da concessionária ELEKTRO, sendo a fixação do sistema sitiada
sobre os telhados das salas de aula containers. De acordo com os dados meteorológicos expostos, fica
evidente um potencial a ser explorado pelo mercado fotovoltaico para esta localidade devido aos altos
valores de irradiância solar. Para fundamentar este trabalho, uma revisão dos conceitos necessários
para a análise de projetos será elaborada, levando a atenção mais para os conceitos, sendo estes as
mesmas bases de um curso de engenharia eletrônica. As abordagens matemáticas deste trabalho
serão relativamente simples, no entanto em determinados pontos poderá ficar extremamente extenso e
repetitivo. Sob estas condições, o uso de sistemas computacionais se tornará indispensável a fim de
expressar uma melhor precisão dos resultados de geração elétrica anual. Fora empregado o uso do
software PVsyst, auxiliando nos cálculos e projeções para a geração anual que o sistema fotogerador
irá apresentar no decorrer de cada mês do ano, em um período de 12 anos. A simulação realizada leva
em conta variáveis climáticas locais, geometria das edificações, cálculos elétricos e quantificações da
perdas envolvidas no processo. O sistema proposto busca abater parcialmente (se não toda) energia
consumida pelo campus, demonstrando uma produção anual de energia de 72,9 MWh / Ano. O
excedente de energia injetado na rede será convertido em créditos com a concessionária, de forma a
reduzir ao mínimo os custos com consumo de energia elétrica do campus.
This final papper aims to present an arrangement for generating electrical energy from renewable sources, in this case, a solar generation array with a capacity greater than 60 MWh/year. The photogenerator system for this analysis will be considered at the location of UNESP campus in São João da Boa Vista and will be connected to the ELEKTRO utility grid. The system will be installed on the roofs of the container classrooms. Based on the provided meteorological data, there is evident potential to be explored by the photovoltaic market in this location due to the high solar irradiance values. To support this work, a review of the necessary concepts for project analysis will be elaborated, focusing on the fundamental concepts, which form the basis of an electronic engineering course. The mathematical approaches in this work will be relatively simple, however, in certain aspects, it may become lengthy and repetitive. Under these conditions, the use of computer systems will be essential to express a more accurate annual electrical generation result. The PVsyst software was used, assisting in calculations and projections for the annual generation that the photogenerator system will exhibit throughout each month of the year, over a period of 12 years. The simulation takes into account local climatic variables, building geometry, electrical calculations, and quantification of losses involved in the process. The proposed system aims to partially (if not entirely) offset the energy consumed by the campus, demonstrating an annual energy production of 72.9 MWh/year. The surplus energy injected into the grid will be converted into credits with the utility company, minimizing the costs associated with campus electricity consumption.
