Abstract(s)
A emissão de gases devido à produção de energia elétrica com recurso a combustíveis fósseis é responsável por grande parte da poluição de todo o mundo. Estima-se, ainda, uma redução acentuada do petróleo nos próximos 50 anos.
É perante este cenário que a EEM-Empresa de Eletricidade da Madeira está a colaborar no projeto “Porto Santo sustentável-Smart Fossil Free Island”, que consiste na criação da primeira ilha inteligente do mundo, livre de produção elétrica proveniente de combustíveis fósseis. Assim, é neste contexto que surge o projeto de ligação elétrica entre as duas ilhas, através de um cabo elétrico submarino [1].
Para a realização fundamentada deste projeto, desenvolve-se um estudo das soluções tecnológicas relativamente às REE-Redes de Energia Elétrica e efetua-se um levantamento de soluções industriais para a concretização desta ligação, equacionando-se as soluções HVAC-High Voltage Alternating Current e HVDCHigh Voltage Direct Current.
Para uma análise pormenorizada do comportamento da rede de energia elétrica da RAM, estuda-se a sua organização e funcionamento atual, e utilizando o software de simulação PSSE-Power System Simulation for Engineering, cria-se um modelo equivalente das redes para comparar o comportamento simulado ao real.
Simulam-se as REE com e sem interligação elétrica e, efetua-se uma análise em regime permanente e transitório. Testam-se as soluções HVAC e HVDC-VSCVoltage Source Converter para vários cenários com trânsito de potência bidirecional. Nestes, analisa-se o comportamento da rede perante falhas.
Por fim, efetua-se um estudo de viabilidade económica para as soluções apresentadas e recomenda-se a solução que melhor satisfaz as finalidades deste projeto com os melhores parâmetros de qualidade.
Projeta-se e estuda-se, ainda, a viabilidade técnica e económica de um parque offshore, verificando-se ser viável.
Em suma, através de toda a análise efetuada neste trabalho conclui-se que esta ligação é tecnologicamente e economicamente viável, sendo recuperado o valor de investimento em aproximadamente 18 anos.
The emission of gases from fossil fuels is responsible for much of the pollution around the world. In addition, the shortage of petrol is imminent, reason why its end is estimated for the next 50 years. It was against this background that the Madeira Electricity Company announced the project "Sustainable Porto Santo - Smart Fossil Free Island", which will consist in the creation of the first intelligent island of the planet and the first totally free of electricity production from fossil fuels island. Thus, it is in this context that the project of electrical connection between Madeira island and Porto Santo island through an electric submarine cable appears. For the reasoned accomplishment of this project, a study of the art regarding the electric energy networks was developed and a survey of industrial solutions for the realization of this connection was made, considering the HVAC-High Voltage Alternating Current and HVDC-High Voltage Direct Current solutions. For a detailed analysis of the behavior of the electric power network of each island, its current organization and operation were studied, using the simulation software PSSE-Power System Simulation for Engineering to compare it to the behavior of the interconnected networks. In the first phase, the electric power networks were tested without interconnection and then a permanent and dynamic analysis was carried out. In this analysis, the HVAC and the HVDC-VSC solutions were tested for several simulation scenario, in which the connection is made in both directions. These scenarios included some faults, in order to analyze the network’s behavior. Finally, an economic viability study was performed for the solutions presented and the solution that best meets the objectives of this project with the best quality parameters was recommended. Also, the technical and economic viability of an offshore park, confirming its reliability. Throughout the analysis carried out in this work it was concluded that this project is technologically and economically viable, recovering the investment value in about 18 years.
