Abstract(s)
As centrais fotovoltaicas, representam fontes de produção de energia elétrica através
do recurso a uma fonte energia renovável com um potencial “infinito”. Energia elétrica
que posteriormente poderá ser utilizada em diversas aplicações como o consumo
doméstico, consumo industrial ou armazenamento. Contudo, para que durante a sua
utilização se consigam atingir os níveis de produção estimados e garantir o fornecimento
da procura, é imprescindível uma boa performance destas centrais. Isto significa que
durante o ciclo de vida de um parque fotovoltaico existirão diversas intervenções de
manutenção, tais como reparação ou substituição de módulos fotovoltaicos, inversores,
transformadores e dispositivos de seccionamento de alta tensão para que se garanta a
performance estimada e para que possam ser cumpridos todos os contratos associados.
Assim configura-se como apropriado determinar o impacto destas atividades de
manutenção durante o ciclo de vida da instalação fotovoltaica. Com este trabalho
pretende-se a criação de uma matriz de avaliação de sustentabilidade, que possa
posteriormente ser usada em futuras instalações no processo de tomada de decisão,
contribuindo para o aumento da qualidade de uma instalação e futuras atividades mais
sustentáveis. Na aplicação da matriz num caso de estudo foi possível concluir que a
dimensão ambiental foi a que sofreu maior impacto. Desta foram, foram calculadas
quantitativamente as emissões produzidas durante as diversas ações de manutenção,
tendo-se percebido que a manutenção corretiva tem um maior impacto na emissão de
poluentes para a atmosfera.
Photovoltaic plants represent sources of electricity production by using a renewable energy source with "infinite" potential. This electric energy can later be used in various applications such as domestic consumption, industrial consumption, or storage. However, to reach the estimated production levels during their use and to guarantee the supply of demand, good performance of these plants is essential. This means that during the life cycle of a photovoltaic park there will be several maintenance interventions, such as repair or replacement of photovoltaic modules, inverters, transformers, and high voltage isolating devices in order to fulfil contracts established and to guarantee the estimated performance. Thus, it is appropriate to determine the impact of these maintenance activities during the life cycle of the photovoltaic installation. With this work, we intend to create a sustainability assessment matrix, which can later be used in future installations for the decision-making process, contributing for increasing the quality of an installation and more sustainable future activities. Applying the matrix in a case study, it was possible to conclude that the environmental dimension was the one that suffered the greatest impact. Thus, the emissions produced during the various maintenance actions were quantitatively calculated, having realized that corrective maintenance has a greater impact on the emission of pollutants into the atmosphere.
