Resumo: | Brazil has one of the largest energy generation and transmission systems in the world, with continental dimensions, consisting of a nearly interconnected system. Currently, more than 98% of national power generation and transmission is connected to the National Interconnected System - SIN, responsible for achieving a better distribution between an energy supply and demand in the country, ensuring the supply and controlling the level of the hydroelectric reservoirs, as well as generating energy from other sources. Electric power transmission systems are basically composed of two parts, as transmission lines and as substations, the substations have as their most costly component the power transformer, representing about 60% of the value of the substation. Due to the aging of these equipments, it is necessary to create methodologies that assist as energy concessions in the decision making on a replacement of these equipments. In this context, this dissertation had the objective of proposing a methodology to analyze the costs generated by power transformer shutdowns in substations, both for programmed shutdowns and for others. This cost wad calculated through cost due to the variable portion and costs generated by equipment life reduction. The methodology was tested in the CEEE-GT area, 240 shutdowns of 69 sets of real transformers installed in the extreme south of Brazil were analyzed over a period of 5 years. The results showed that the average values related to the variable portion exceeded R$ 17,000.00 per unit while the values referring to the anticipation of the replacement reached values of up to R$ 50,000.00 per unit. The total cost of unavailability reached R$ 1,338,575.75, showing the importance of analyzing these costs. |

Atualmente, mais de 98% da geração e transmissão de energia nacional está conectada ao Sistema Interligado Nacional – SIN, responsável por realizar uma melhor distribuição entre a oferta e a demanda de energia no país, garantindo o abastecimento e controlando o nível dos reservatórios das hidrelétricas, assim como a geração de energia através de outras fontes. Os sistemas de transmissão de energia elétrica são compostos basicamente por duas partes, as linhas de transmissão e as subestações, estas possuem como componente de maior custo o transformador de potência, representando cerca de 60% do valor da subestação. Devido ao envelhecimento destes equipamentos, com boa parte chegando próximo ao fim de vida útil, torna-se necessária a criação de metodologias que auxiliem as concessionárias de energia na tomada de decisão sobre a substituição destes equipamentos. Neste contexto, esse trabalho de dissertação teve o objetivo de propor uma metodologia para analisar os custos gerados pelos desligamentos de transformadores de potência em subestações, tanto para os desligamentos programados quanto para os demais. Este custo foi calculado através dos custos devido à parcela variável e dos custos gerados pela redução de vida dos demais equipamentos devido ao sobrecarregamento gerado quando um dos equipamentos é desligado. A metodologia foi testada na área de atuação da CEEE-GT, sendo analisados 240 desligamentos de 69 conjuntos de transformadores reais instalados no extremo sul do Brasil, durante um período de 5 anos. Os resultados mostraram que os valores médios referentes à parcela variável ultrapassaram os R$ 17.000,00 por unidade enquanto os valores referentes à antecipação da substituição atingiram valores de até R$ 50.000,00 por unidade. O custo total das indisponibilidades chegou à R$ 1.338.575,75, mostrando a importância da análise desses custos.porUniversidade Federal de Santa MariaCentro de TecnologiaPrograma de Pós-Graduação em Engenharia de ProduçãoUFSMBrasilEngenharia de ProduçãoAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessGestão de energiaMensuração de desempenhoTransformadores de potênciaIndisponibilidade de transformadoresSubstituição de equipamentosEnergy managementPerformance measurementPower transformersUnavailability of transformersEquipment replacementCNPQ::ENGENHARIAS::ENGENHARIA DE PRODUCAOMetodologia para análise de custos da indisponibilidade de transformadores de potência em subestaçõesMethodology for cost analysis of the unsuitability of power transformers in substationsinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisSiluk, Julio Cezar Mairessehttp://lattes.cnpq.br/8315298509051752Marchesan, Tiago Bandeirahttp://lattes.cnpq.br/2318413245910780Guimaraes, Gil Eduardohttp://lattes.cnpq.br/8142709905105377Schneider, Paulo Smithhttp://lattes.cnpq.br/5381018862828370http://lattes.cnpq.br/9577894959138101Campanhola, Filipe Possatti300800000005600459ed50f-f433-4c93-a8c8-5a7d43df4239efc1f256-15b9-4fbd-aff1-e07db7dfab1639eece81-e605-4d6f-98a8-8273aa802a22d54a502d-7970-44b6-8d87-e5559d7260d177eed1f9-9d3d-423a-a989-6d4ee3a6d52breponame:Biblioteca Digital de Teses e Dissertações do UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALDIS_PPGEP_2018_CAMPANHOLA_FILIPE.pdfDIS_PPGEP_2018_CAMPANHOLA_FILIPE.pdfDissertação de Mestradoapplication/pdf1748548http://repositorio.ufsm.br/bitstream/1/14550/1/DIS_PPGEP_2018_CAMPANHOLA_FILIPE.pdfb83ebf55627917faa3db4e55cd1a9dacMD51CC-LICENSElicense_rdflicense_rdfapplication/rdf+xml;
