Resumo: | Photovoltaic water pumping systems are commercialized as closed sets of specific components (kits) at a high cost. Nevertheless, it is possible to develop solutions based on standard components, reliable, widely available and cheaper. These solutions use standard frequency converters and AC pumps. Although it is possible to connect a high voltage photovoltaic string directly to a standard frequency converter, the string becomes oversized for low power applications, bellow several hundreds of Watts. This work develops and validates new approaches for low power applications using only up to four photovoltaic modules. The first approach uses up to 4 photovoltaic modules, charge controller, battery, battery inverter, frequency converter and a single-phase pump. The second approach uses a developed boost converter to replace the charge controller, battery and battery inverter. For the first approach, several configurations were tested based on different battery voltage levels (12, 24 and 48V) and technologies. These two approaches were validated successfully. Their results have shown that it is possible to make a system based on standard frequency converters, proving their value for small companies to develop their own cost-effective solutions due to the lower cost, modularity, and availability worldwide. This work was made in cooperation with Valled Soluções Energéticas and CHL Engenharia e Distribuição, which are small companies with experience in photovoltaic lighting and water pumping systems. |

No entanto, é possível desenvolver soluções baseadas em componentes convencionais, confiáveis, amplamente disponíveis e mais baratas. Essas soluções usam conversores de frequência e bombas AC. Embora seja possível conectar uma string fotovoltaica de alta tensão diretamente a um conversor de frequência, a string se torna superdimensionada para aplicações de baixa potência, abaixo de algumas centenas de Watts. Este trabalho desenvolve e valida novas abordagens para aplicações de baixa potência usando no máximo quatro módulos fotovoltaicos. A primeira abordagem utiliza até 4 módulos fotovoltaicos, controlador de carga, bateria, inversor de bateria, conversor de frequência e uma bomba monofásica. A segunda abordagem usa um conversor boost desenvolvido para substituir o controlador de carga, bateria e inversor de bateria. Para a primeira abordagem várias configurações foram testadas com base em diferentes níveis de tensão da bateria (12, 24 e 48V) e tecnologias. Estas duas abordagens foram validadas com sucesso. Seus resultados mostraram que é possível fazer um sistema baseado em conversores de frequência convencionais, provando seu valor para pequenas empresas desenvolverem suas próprias soluções econômicas devido ao menor custo, modularidade e disponibilidade em todo o mundo. Este trabalho foi realizado em cooperação com a Valled Soluções Energéticas e a CHL Engenharia e Distribuição, pequenas empresas com experiência em iluminação e sistemas de bombagem fotovoltaica.Leite, VicenteFritzen, Paulo CíceroBiblioteca Digital do IPBScortegagna, Alberto Kisner2019-11-05T10:25:52Z201920182019-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10198/19761TID:202296458enginfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2023-11-21T10:45:09Zoai:bibliotecadigital.ipb.pt:10198/19761Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T23:10:21.862779Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
