Resumo: | Hydroelectric energy continues to be the most representative renewable resource in the world, accounting today for 40% of installed capacity. The availability of water, combined with the technologies for generating electricity at a reasonable cost, have sustained the success of this type of generation over the years. Continuing to leverage the hydroelectric sector is even more challenging today, because there is a growing world demand for energy, at the same time that the most attractive places from an economic point of view have already been benefited. The current context refers to approaches to water exploitation aimed at exploiting smaller-scale potentials and existing water structures that operate in a multifunctional way. Solidified in this conjecture, the purpose of this study is to contribute, in the sense of attributing alternatives, for the generation of energy in existing low head dams through the pre-dimensioning of a siphon plant. This type of plant is part of a specific and still evolving niche for decentralized power generation. The reduced structural requirements (generator, turbine, and suction tube), as well as the minimal intervention in the existing structure of the dam, the cessation of new socio-environmental and economic impacts related to the construction of a new plant are the main favorable characteristics of these facilities. The case study of an inoperative plant and the tools available in the Homer Software for data simulation were used as methodological resources. Two base configurations were considered: one with 100% renewable matrices and another one including a diesel generator. From them, different hybrid systems, to determine an optimal configuration in terms of net present cost, were simulated. Among the simulations performed, the most promising optimal solution was hybrid, considering among its components a set of siphon turbines totaling 271 kW, plus 50 kW in photovoltaic modules and 140 kW in a diesel support system. A battery bank with 32 200 Ah batteries complemented this system. The energy cost for this system is $0.164 per kWh. For a system without diesel and with 0% service failures, viable results appear only up to 2600 kWh load. |

A disponibilidade de água, aliada às tecnologias de geração de energia elétrica a um custo razoável, tem sustentado o sucesso desse tipo de geração ao longo dos anos. Continuar a alavancar o setor hidrelétrico é ainda mais desafiador hoje, pois há uma demanda mundial crescente por energia, ao mesmo tempo em que os locais mais atrativos do ponto de vista econômico já foram beneficiados. O contexto atual refere-se a abordagens de exploração de água destinadas a explorar potenciais de menor escala e estruturas hídricas existentes que operam de forma multifuncional. Solidificado nesta conjectura, o objetivo deste estudo é contribuir, no sentido de atribuir alternativas, para a geração de energia em barragens de baixa queda existentes através do pré-dimensionamento de uma usina sifão. Esse tipo de usina faz parte de um nicho específico e ainda em evolução para geração descentralizada de energia. Os requisitos estruturais reduzidos (gerador, turbina e tubo de sucção), bem como a intervenção mínima na estrutura existente da barragem, a cessação de novos impactos socioambientais e econômicos relacionados à construção de uma nova usina são os principais fatores favoráveis características dessas instalações. O estudo de caso de uma planta inoperante e as ferramentas disponíveis no Software Homer para simulação de dados foram utilizados como recursos metodológicos. Duas configurações básicas foram consideradas: uma com matrizes 100% renováveis e outra incluindo um gerador a diesel. A partir deles, foram simulados diferentes sistemas híbridos, para determinar uma configuração ótima em termos de custo presente líquido. Dentre as simulações realizadas, a solução ótima mais promissora foi a híbrida, considerando entre seus componentes um conjunto de turbinas sifão totalizando 271 kW, mais 50 kW em módulos fotovoltaicos e 140 kW em sistema de apoio a diesel. Um banco de baterias com 32 baterias de 200 Ah complementava este sistema. O custo de energia para este sistema é de $ 0,164 por kWh. Para um sistema sem diesel e com 0% de falhas de serviço, os resultados viáveis aparecem apenas até 2600 kWh de carga.Universidade Federal de Viçosa - UFV2024-01-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/jcec/article/view/1639210.18540/jcecvl10iss1pp16392The Journal of Engineering and Exact Sciences; Vol. 10 No. 1 (2024); 16392The Journal of Engineering and Exact Sciences; Vol. 10 Núm. 1 (2024); 16392The Journal of Engineering and Exact Sciences; v. 10 n. 1 (2024); 163922527-1075reponame:Revista de Engenharia Química e Químicainstname:Universidade Federal de Viçosa (UFV)instacron:UFVenghttps://periodicos.ufv.br/jcec/article/view/16392/9158Copyright (c) 2024 The Journal of Engineering and Exact Scienceshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessPizutti, Janaina TerhorstGaldino, Carlos Henrique Pereira AssunçãoMeirelles, Fernando Setembrino CruzBeluco, Alexandre2024-03-26T17:19:32Zoai:ojs.periodicos.ufv.br:article/16392Revistahttp://www.seer.ufv.br/seer/rbeq2/index.php/req2/indexONGhttps://periodicos.ufv.br/jcec/oaijcec.journal@ufv.br||req2@ufv.br2446-94162446-9416opendoar:2024-03-26T17:19:32Revista de Engenharia Química e Química - Universidade Federal de Viçosa (UFV)false |
