Abstract(s)
Observando o constante crescimento das fontes energéticas limpas, viu-se a oportunidade
de desenvolvimento na matriz fotovoltaica. O objetivo do trabalho foi elaborar um controlador
digital, para o seguidor solar horizontal, que apresentasse: controle de movimentação,
sistema de segurança contra ventos fortes e limpeza automatizada. A dissertação
teve sua origem em uma proposta apresentada por uma empresa da região de Bragança
e aborda a criação do produto.
Foram analisados diversos estudos e sistemas atuais, buscando caracterizar o produto
a ser desenvolvido, no decorrer da dissertação é explicado cada característica e o porquê
da mesma ser escolhida. Foi elaborado, baseado na modelagem matemático, um método
de monitoramento do índice de sujeira sobre os painéis fotovoltaicos. O controlador
ainda apresenta limpeza automatizada feita por aspersão de água em um ciclo fechado;
rastreamento solar por sensor virtual e movimento utilizando pistão eletrônico.
Entretanto não foi possível aplicar o sistema em uma escala real devido às particularidades
da própria empresa. Foi possível verificar o funcionamento do sistema a partir
de testes por softwares e de simuladores, obtendo como resultado um aumento na geração
fotovoltaica de 22.04% em relação ao sistema fixo, ao realizar o teste no sistema de
monitoramento de sujidade foi obtido um resultado de erro relativo igual a 2,04%. Com
os resultados obtidos foi possível estimar uma alta confiabilidade do sistema, assim como
robustez e aplicabilidade, demonstrando que o produto elaborado está apto ao mercado
atual de seguidores solares além de ter vantagem sobre os demais modelos por possuir
monitoramento da sujidade automático.

The dissertation had its origin in a proposal presented by a company from the region of Bragança and addresses the creation of a product. Foi analisado diversos estudos e sistemas atuais, seeking to characterize the product to be develope, in the course of the dissertation, each characteristic is explained and why it was chosen. Based on mathematical modeling, a method for monitoring the dirt index on photovoltaic panels was developed. The controller also features automated cleaning done by spraying water in a closed cycle; solar tracking by virtual sensor and movement using electronic piston. However, it was not possible to apply the system on a real scale for reasons of the company itself. It was possible to verify the functioning of the system from tests by software and simulators, obtaining as a result an increase in photovoltaic generation of 22.04% in relation to the fixed system, when performing tests on the dirt monitoring system, results were obtained from relative error equal to 2.04%. With the results it was possible to estimate great reliability of the system, robustness and applicability, demonstrating that the elaborated product is apt for the current market of solar trackers besides having advantage over the other models for having automatic dirt monitoring. Keywords: renewable energy; photovoltaic generation; horizontal solar tracker; virtual sensor; soiling monitoring.
