Abstract(s)
Em Portugal, a capacidade eólica onshore encontra-se perto do limite, não só pela existência de restrições geográficas e técnicas, mas também pela adoção de políticas de regulação e incentivo que influenciam as perspetivas de futuro desta fonte energética. As empresas de energia eólica começam a direcionar os seus projetos para outros mercados emergentes, com elevado potencial de desenvolvimento, recurso eólico abundante e com perspetivas crescentes de consumo de energia elétrica. Este trabalho pretende desenvolver uma metodologia para apoio ao desenvolvimento de projetos de parques eólicos localizados em áreas remotas, recorrendo a dados meteorológicos e topográficos locais pelo recurso a bases de dados mundiais de recurso eólico. O adequado tratamento das informações recolhidas por estações meteorológicas permite definir o potencial eólico de cada região e determinar a viabilidade técnico-económica de cada projeto. Tratando-se de uma tese elaborada em ambiente empresarial, esta visa retratar a realidade no desenvolvimento de projetos de centrais eólicas, bem como disseminar conhecimento genérico do desenvolvimento de projetos na realidade atual, com a escassez de locais e a tendência global de viabilização de projetos em regimes regulatórios voláteis. Este trabalho inclui o desenvolvimento de uma aplicação capaz de simular a viabilidade económica de um projeto com estas características. A seleção do local será efetuada através da modelização por software do local, procedendo primariamente à recolha de dados e análise de medições, as correlações desta informação com os dados de longo prazo disponíveis com o objetivo de minimizar as incertezas associadas ao desenvolvimento de uma central eólica. A tese validará ainda o perfil vertical do vento (windshear), a modelização do fluxo, entrando em conta com a rugosidade do local escolhido. Assim, a seleção entre a vasta gama de aerogeradores ocorrerá com a aplicação do software e dos modelos de cálculo, permitindo a confirmação da compatibilidade dos equipamentos para o local e aferir a viabilidade do investimento.
In Portugal, onshore wind capacity is close to the limits, not only due to the existence of geographical and technical restrictions, but also by the adoption of regulation and incentive policies that influence the future prospects based on this energy source. The wind energy companies are beginning to focus their projects to other emerging markets, with high potential for development, abundant wind resource and with growth perspectives for electricity consumption. This work intends to develop a methodology to support the development of wind farms projects located in remote areas, using local meteorological and topographical data through the use of global wind resource databases. The appropriate treatment of the information collected by meteorological stations allows to define the wind potential of each region and determine the technical and economic viability of each project. Being a thesis elaborated in a company environment, it’s aim is to portray the reality in the development of wind farms projects, as well as to disseminate generic knowledge of the development of projects in the current market conditions, with the scarcity of locations and the global tendency of projects that should be viable with volatile regulatory regimes. This work includes the development of an application capable of simulating the economic viability of a project with these characteristics. Site selection will be carried out through site software modeling, primarily by collecting data and analyzing measurements, correlating this information with available long-term data in order to minimize the uncertainties associated with the development of a wind farm. The thesis will also validate the windshear and the flow modeling, taking into account the roughness of the chosen site. Thus, the selection of the wide range of wind turbines will occur with the application of the software and the calculation models, allowing the confirmation of the compatibility of the equipment to the site and the confirmation if the investment is viable.
