Abstract(s)
Há muitos séculos, que o Homem vem procurando formas de ter iluminação durante a noite, assim como em espaços escuros, como grutas, caves e túneis. Para o efeito, várias tecnologias têm sido desenvolvidas: candeias de azeite; velas; candeeiros a querosene; candeeiros a gás; tendo-se chegado à atual iluminação elétrica.
A iluminação pública está diretamente ligada ao conforto das pessoas e à segurança nas vias públicas. Os principais objetivos são a visibilidade do trajeto a percorrer, a prevenção de criminalidade e a iluminação de monumentos, permitindo o seu embelezamento e destaque noturno.
As finalidades deste projeto são o estudo, o desenvolvimento e a análise da viabilidade técnico-económica de sistemas autónomos de iluminação pública em estradas ou caminhos rurais com energias renováveis, nomeadamente energia solar fotovoltaica, aproveitando a energia remanescente para alimentar cargas nas zonas dentro das localidades.
Em Cabo Verde, a iluminação pública (IP) é responsável por 10% do consumo energético. No entanto, tem-se verificado nos últimos anos uma tendência de aumento da rede de IP, o que implica um conjunto de medidas direcionadas ao aumento da eficiência energética no parque de IP [1]. Este elevado consumo de energia, na iluminação pública, faz com que esta seja uma parte bastante significativa das despesas dos produtores. Por outro lado, também tem havido uma preocupação em reduzir as emissões de CO2. Deste modo, nos últimos anos tem-se procurado implementar medidas que levem a uma maior eficiência energética, sendo isto possível com a utilização de novas tecnologias de iluminação, como luminárias LED e/ou sistemas de controlo, gestão de IP e geração de energia através de fontes solares fotovoltaicas.
For many centuries, Man has been looking for ways to have lighting at night, as well as in dark spaces, such as caves, cellars, and tunnels. For this purpose, several technologies have been developed: oil lamps; candles; kerosene lamps; gas lamps; having reached the current electric lighting. Public lighting (PL) is linked to people's comfort and safety on public roads. The main objectives are the visibility of the route to be taken, the prevention of crime and the illumination of monuments, allowing them to be beautified and highlighted at night. The purposes of this project are the study, development and analysis of the technical and economic feasibility of autonomous public lighting systems on rural roads or paths with renewable energy, namely solar photovoltaic energy, taking advantage of the remaining energy to feed loads in the areas within the localities. In Cape Verde, PL is responsible for 10% of energy consumption. However, there has been a trend towards increasing the PL network in recent years, which implies a set of measures aimed at increasing energy efficiency in the PL park [1]. This high energy consumption at PL makes this a significant part of producers' expenses. On the other hand, there has also been a concern to reduce CO2 emissions. Thus, in recent years, efforts have been made to implement measures that lead to greater energy efficiency, which is possible with the use of new lighting technologies, such as LED luminaires and / or control systems, PL management and energy generation through photovoltaic solar sources.
