Abstract
As variações de intensidade solar, temperatura ambiente ou carga, são parâmetros que alteram o ponto ótimo de operação
de um gerador fotovoltaico. Desta forma, deve-se analisar o seu comportamento, a fim de otimizar seu funcionamento.
Este trabalho visou apresentar a modelagem e a simulação de um gerador fotovoltaico mediante características fornecidas
pelo fabricante, utilizando-se programas de digitalização de curvas e simulação (Simulink do Matlab®), analisando
seu comportamento em relação à variação de intensidade solar e temperatura, comparando as curvas obtidas com as
fornecidas pelo fabricante. Os resultados obtidos foram satisfatórios, validando o modelo utilizado para simulação de
geradores fotovoltaicos.
Solar intensity, ambient temperature or load variations are parameters which change the optimal operation point of photovoltaic generators. Thus, one must analyze its behavior in order to optimize its functioning. This study aimed at modeling and simulating a photovoltaic generator following the characteristics informed by the manufacturer. With the use of computer programs of curve digitalization and simulation (Simulink do Matlab®), the behavior of the generator was analyzed relative to temperature and solar intensity variations, and compared with the information supplied by the manufacturer. The results were satisfactory and the proposed model was valid for simulation of photovoltaic generators.
