Resumo: The demand for electricity grows in the same way as the consumers requirement for an uninterrupted supply. Many reliability indices are applied by regulatory agencies, utilities and consumers for measuring the power systems reliability. The improvement of such indices has been required by regulatory agencies and pursued by energy distributors. Therefore, the application of automatic restauration systems has gained relevance as a support tool for control center operators for a quick and secure restauration of faulty electric networks. This work proposes two contributions to the restoration process of radial power system networks. The former is a multiobjective algorithm for effective switch placement in distribution networks. Multiobjective optimization techniques are applied to achieve a set of non-dominated solutions rather than an unique one. Therefore, the decision making for switch placement is eased by the flexibility given from the multiple solutions. The latter contribution is a model for automatic restoration of power distribution networks adaptable to the network topology changes and able to ensure the operational security of the power system network. The proposed model is based on coloured Petri nets as the modelling tool. Reusability and extensibility features have been pursued and implemented on the proposed model. As a result, the needed time to restore faulty power system networks is reduced without compromising its operational security. Case studies are presented demonstrating the benefits to the power system distribution utilities obtained with the deployment of the proposed tools to improve the reliability of the power system networks.

Diversos Ãndices de confiabilidade sÃo utilizados por agÃncias reguladoras, concessionÃrias e consumidores para aferir a continuidade dos sistemas elÃtricos de potÃncia. A melhoria de tais Ãndices vem sendo requisitada por agÃncias reguladoras e perseguida pelas concessionÃrias de energia. Para tanto, o uso de sistemas de restauraÃÃo automÃtica vem ganhando destaque como uma ferramenta de apoio a operadores de centros de controle para a restauraÃÃo rÃpida e segura de redes elÃtricas em situaÃÃes de falta. Este trabalho apresenta duas contribuiÃÃes para a restauraÃÃo automÃtica de redes radiais de distribuiÃÃo de energia. A primeira consiste em um algoritmo para o posicionamento eficiente de chaves telecontroladas em redes de distribuiÃÃo. TÃcnicas de otimizaÃÃo multiobjetivo sÃo aplicadas para obter-se como resultado um conjunto de soluÃÃes nÃo-dominadas ao invÃs de uma Ãnica soluÃÃo. Com isso, a tomada de decisÃo para o posicionamento eficiente de chaves na rede elÃtrica à facilitado pela flexibilidade das mÃltiplas soluÃÃes oferecidas pelo algoritmo proposto. A segunda contribuiÃÃo do trabalho consiste em um modelo para restauraÃÃo automÃtica da rede de distribuiÃÃo de energia adaptÃvel Ãs mudanÃas de topologia e que garante a seguranÃa operacional da rede elÃtrica. O modelo proposto fundamentou-se em Redes de Petri Coloridas como ferramenta de modelagem. CaracterÃsticas de reusabilidade e extensibilidade foram buscadas e implementadas no modelo proposto. Como resultado, o tempo necessÃrio para restaurar redes elÃtricas em condiÃÃo de falta à reduzido sem comprometer a seguranÃa do sistema elÃtrico. Estudos de caso sÃo apresentados evidenciando os benefÃcios para concessionÃrias de distribuiÃÃo de energia com a implementaÃÃo das ferramentas propostas para melhoria da confiabilidade da rede elÃtrica.Conselho Nacional de Desenvolvimento CientÃfico e TecnolÃgicohttp://www.teses.ufc.br/tde_busca/arquivo.php?codArquivo=16190application/pdfinfo:eu-repo/semantics/openAccessporreponame:Biblioteca Digital de Teses e Dissertações da UFCinstname:Universidade Federal do Cearáinstacron:UFC2019-01-21T11:29:30Zmail@mail.com -
