Estudo do sistema de controle e aplicabilidade de um sistema fotovoltáico com seguidor solar de um eixo utilizando um servomotor.

Abstract

The market has evolved more and more, and the demand for a solar generation system has grown gradually, with this new technologies are continuously launched on the market in order to increase the efficiency of solar panels, one of the methods is solar tracking. These methods provide the alignment of the surface of the photovoltaic panels with the angle of solar incidence, following the movement of the Sun throughout the day or throughout the seasons, thus increasing the performance of a photovoltaic generation system. To do the modeling, analysis and simulation of the functioning of the control system of a servomotor, the Simulink tool, developed by the software company MathWorks, will be used. The elements of the system will be modeled in blocks with variable parameters, without using lines of code. Therefore, this study will focus on modeling the elements of the control system, obtaining the position of the panel. Then a case study will be carried out to compare the mobile system with a fixed solar system of the same power. The modeled and simulated elements will be: solar position, voltage source, error, finite state machine (microntroller), transference function and meters.
