Análise de tensões e de campos eletromagnéticos produzidos em arranjo fotovoltaico aplicando o método dos elementos finitos

Abstract

The objective of this work is to perform the modeling of a photovoltaic arrangement, applying the FETD, allowing a realistic computational simulation to determine the distribution of the electromagnetic fields and of the voltages in the photovoltaic cells and arrangements. We present an efficient and robust numerical algorithm for the analysis of photovoltaic cells, based on finite elements. It was verified that through the experiments, the proposed algorithm solves the scalar electromagnetic wave equations, being able to perform simulations with ultrashort pulses and high frequencies, using the Newmark-𝛽 method the algorithm is unconditionally stable. The main objectives were achieved in the development of this research, among them, the modeling of a photovoltaic arrangement, allowing to determine the distribution of the electromagnetic fields. The numerical results were satisfactory, showing agreement with the results obtained analytically.
