Abstract(s)
Este trabalho é realizado no âmbito da dissertação de mestrado em Engenharia
Eletrotécnica – Sistemas Elétricos de Energia. O tema desta dissertação é a análise de efeitos e
riscos em ativos de muito alta tensão. Numa fase inicial deste trabalho é feita uma
contextualização ao tema e são partilhados os objetivos do trabalho proposto. Foi também
realizado um estado da arte relativo a tópicos que estão relacionados com o tema principal do
trabalho. Neste documento é apresentada uma caracterização da Rede Nacional de Transporte
e dos ativos pertencentes a uma rede de transporte de energia elétrica. É abordado também
um tópico relacionado com manutenções, onde são apresentadas diferentes políticas de
manutenção, desde políticas de manutenção corretiva, preventiva e preditiva. São
apresentadas duas metodologias de cálculo com vista no cálculo de índices de saúde e
criticidade dos ativos, para análise de estado e de risco dos mesmos. É feita uma aplicação
destas metodologias a dois tipos de dispositivos, disjuntores e seccionadores, são também
elaborados casos hipotéticos de estudos, de modo a avaliar possíveis resultados do uso destas
metodologias. Na conclusão deste trabalho é abordada a importância da necessidade de
manutenção dos ativos pertencentes à rede de transporte de energia elétrica e da correta
aplicação das diferentes políticas de manutenção utilizadas. Conclui-se que recorrer ao cálculo
de índices de saúde e criticidade é benéfico para a análise do estado e criticidade de ativos,
sendo uma mais-valia para priorizar ações de intervenção entre ativos.
This work is being carried out as part of a master's dissertation in Electrical Engineering - Electrical Power Systems. The subject of this dissertation is the analysis of effects and risks in extra high voltage assets. At an early stage of this work, the topic is contextualized and the objectives of the proposed work are shared. A state of the art was also carried out on topics that are related to the main theme of the work. This document presents a characterization of the National Transmission Network and the assets belonging to an electricity transmission network. A topic related to maintenance is also covered, where different maintenance policies are presented, ranging from corrective, preventive and predictive maintenance policies. Two calculation methodologies are presented, with a view to calculating asset health and criticality indices, for analyzing asset status and risk. These methodologies are applied to two types of devices, circuit breakers and disconnectors, and hypothetical case studies are also drawn up in order to evaluate the possible results of using these methodologies. The conclusion of this work addresses the importance of the need for maintenance of assets belonging to the electricity transmission network and the correct application of the different maintenance policies used. It is concluded that the use of health and criticality indices is beneficial for analyzing the condition and criticality of assets, and is an asset for prioritizing intervention actions among assets.
