Title in Portuguese
"Análise do fator de dimensionamento do inversor (FDI) aplicado a sistemas fotovoltaicos conectados à rede (SFCR)"
Keywords in Portuguese

Sistemas fotovoltaicos
Abstract in Portuguese
Esta tese apresenta a análise de resultados teóricos, correspondentes a simulações numéricas para várias localidades brasileiras, e experimentais, relativos ao sistema fotovoltaico conectado à rede elétrica (SFCR), de 11,07 kWp, instalado na fachada do prédio da administração do Instituto de Eletrotécnica e Energia da Universidade de São Paulo (IEE/USP), enfatizando-se a influência da capacidade relativa entre o inversor e o gerador fotovoltaico, também conhecido como Fator de Dimensionamento do Inversor (FDI). Apesar das diferentes localidades estudadas e dos diferentes tamanhos dos geradores fotovoltaicos, constatou-se que, para uma determinada faixa de FDI, as produtividades anuais obtidas em kWh/kWp não diferem significativamente, indicando que o cuidado com a escolha de bons equipamentos torna-se mais relevante em termos energéticos do que a própria relação FDI.

Abstract in English
This thesis presents the analysis of theoretical results, corresponding to numeric simulations for several locations in Brazil, and experimental results, relative to the grid-connected photovoltaic system (GCPVS) of 11.07 kWp, installed in the facade of the administration building of the Instituto de Eletrotécnica e Energia da Universidade de São Paulo (IEE/USP), emphasizing the influence of the relative size between the inverter and the photovoltaic generator, also known as Sizing Factor of the Inverter (SFI). In spite of the different location studied and of the different sizes of the photovoltaic generators, it was verified that for a SFI's certain range, the annual yields obtained in kWh/kWp do not differ significantly, indicating that the care with the choice of good equipament, becomes more important in terms of energey production than the relation SFI itself.
