The increase in energy demand, accompanied by the concern to reduce environmental impacts, has intensified the research and use of renewable energy sources. In this context, pico-hydro systems have been intensively investigated due to being environmentally sustainable and for their potential in complementing distributed generation systems and microgrids. Within this class of power generation, water wheels are a prominent choice in sites with low heads and flowrates. Although they may seem a rudimentary solution for the present scenario, in the last two decades, they have returned to the interest of the scientific community and can be an effective alternative for generating clean energy in rural and remote areas without access to the conventional power grid. In urban centres with a well-established power grid, water wheels, such as photovoltaic systems, can contribute to meeting the ever-increasing demand for electricity. One of the main challenges for this technology dissemination lies in the fact that the design of the system depends on the characteristics of the place where it will be installed and, usually, it is done in such a way that the water wheel operates in a very narrow speed range. In this context, this work presents the design and mathematical modelling of an overshot water wheel, as well as the application of theoretical models to estimate its efficiency, aiming to identify its behaviour within an operational range. From the results, the design of a grid-connected pico-hydro system was made, based on permanent magnet synchronous generators and conventional photovoltaic micro-inverters, allowing the water wheel to operate at variable speed. Additionally, the integration with the grid using conventional photovoltaic micro-inverters, as presented in this work, can facilitate the dissemination of these systems, as they are a mature and ready-to-use technology.

520 $a The increase in energy demand, accompanied by the concern to reduce environmental impacts, has intensified the research and use of renewable energy sources. In this context, pico-hydro systems have been intensively investigated due to being environmentally sustainable and for their potential in complementing distributed generation systems and microgrids. Within this class of power generation, water wheels are a prominent choice in sites with low heads and flowrates.

520 $a O aumento da demanda energetica, acompanhado da preocupacao em reduzir os impactos ambientais, intensificou a pesquisa e o uso de fontes de energias renovaveis. Nesse contexto, os sistemas pico-hidricos tem sido intensamente investigados por serem ambientalmente sustentaveis e pelo seu potencial em complementar sistemas de geracao distribuida e microrredes. Nessa classe de geracao de energia, as rodas d'agua sao uma escolha proeminente em locais com baixas quedas e caudais. Embora possam parecer uma solucao rudimentar para o cenario atual, nas ultimas duas decadas elas voltaram ao interesse da comunidade cientifica, podendo ser uma alternativa eficaz para geracao de energia limpa em areas rurais e remotas sem acesso a rede eletrica convencional. Em centros urbanos com a rede eletrica bem estabelecida, tal como os sistemas fotovoltaicos, as rodas d'agua podem contribuir para o atendimento da crescente demanda por energia eletrica. Um dos principais desafios para a sua disseminacao esta no fato de que o projeto do sistema depende das caracteristicas do local onde sera instalado e, normalmente, e feito de forma que a roda d'agua opere em uma faixa de velocidade muito estreita. Neste contexto, este trabalho apresenta o projeto e modelagem matematica de uma roda d'agua overshot, bem como a aplicacao de modelos teoricos para estimar sua eficiencia, visando identificar seu comportamento dentro de uma faixa operacional. A partir dos resultados, o projeto de um sistema pico-hidrico conectado a rede foi realizado, baseado em geradores sincronos de imas permanentes e micro inversores fotovoltaicos convencionais, permitindo que a roda d'agua opere em velocidade variavel. Alem disso, a integracao com a rede utilizando esta tecnologia, como apresentada nesse trabalho, pode facilitar a disseminacao desses sistemas, por serem uma tecnologia madura e pronta para uso.
