Os motores elétricos no Brasil são responsáveis pelo consumo de cerca de 25 porcento de toda a energia elétrica no país e, em sua grande parte, estão presentes na indústria. Estes equipamentos são fabricados para uso em bombas hidráulicas, compressores de ar, elevadores etc., podendo ser comercializados se atenderem aos índices de eficiência mínimos definidos pela Portaria INMETRO/MDIC N488 de 2010, garantindo o seu perfeito funcionamento e o consumo energético adequado. Contudo, alguns estabelecimentos estão comercializando produtos usados recondicionados, não atendendo à regulamentação desta Portaria, além de reformarem motores sem condições de uso. O objetivo desta dissertação é dimensionar e caracterizar o mercado de revenda e manutenção de motores elétricos de indução recondicionados no Brasil, estimando a perda de energia decorrente do recondicionamento incorreto. A metodologia do trabalho pode ser dividida em cinco etapas: estudo do estado da arte de recondicionamento de motores; quantificação de empresas e funcionários por meio de consultas às bases de dados governamentais; pesquisa de campo em amostras de empresas que fazem recondicionamento; extrapolação do estudo conduzido nas amostras para a população de empresas pesquisadas durante a pesquisa de campo; comparação dos resultados com estudos anteriores e dimensionamento das perdas elétricas do Brasil. Como resultado foi caracterizado e dimensionado o mercado de motores recondicionados, contendo: 6.503 empresas; 24,4 mil funcionários; 45 porcento das empresas realizando revenda de recondicionados; 6,9 milhões de motores recondicionados por ano, totalizando 7,46 porcento de perda, equivalentes a 2,9 Terawatt-hora. Além disso, dos 20 milhões de motores existentes no Brasil em 2016 há uma perda de 8,4 Terawatt-hora por uso de motores recondicionados e um grande aumento da venda de motores importados de baixa qualidade. Foram, assim, atingidos todos os objetivos propostos nesta pesquisa, sendo identificadas as novas tendências do mercado de motores brasileiro e gerando subsídios para o desenvolvimento de novas políticas de eficiência energética no país.
Electric motors in Brazil are responsible for the consumption of about 25 percent of all electricity in the country and, being mostly presented in the industry. These equipments are manufactured for being used in hydraulic pumps, air compressors, elevators, etc., and can be commercialized in compliance with the energy efficiency levels defined by INMETRO/MDIC Ordinance N488 of 2010, ensuring adequate energy consumption. However, some establishments are commercializing refurbished motors, not complying with the regulation considered by the Ordinance, including reforming motors without a minimum condition of use. The aim of this dissertation is to evaluate the Brazilian market of refurbished motors, including resale market and maintenance market, estimating the energy losses due to incorrect reconditioning. The methodology of the work can be divided in five steps: state of the art of refurbished motors; quantifying companies and employees by querying the database come from the government; survey on samples of companies that are doing the refurbishing service; extrapolation of the study conducted in the surveyed samples of companies to the population of companies; comparison of results with previous studies and estimating of energy losses in Brazil. As a result, the market for refurbished motors was characterized and dimensioned, containing: 6 503 companies; 24.400 employees; 45 percent of companies performing resale of refurbished motors; 6.9 million motors being refurbished per year, totaling 7.46 percent of energy losses, equivalent to 2.9 TW h. In addition, of the 20 million motors remaining in Brazil in 2016, there is a loss of 8.4 TW h per use of refurbished motors, and a large increase of the sale of low quality imported motors. Thus, all the proposed objectives in this dissertation were achieved, having been identified the new trends in the Brazilian electric motor market and generating subsidies for energy efficiency policies in the country.

Повний текст джерелаThe electric power losses due to thefts and frauds, also called Non technical Losses (NTL), have been priority matter for concessionary companies of electric power distribution, as well as for government regulatory agencies, not only due to rapid growth over the past years but also due to its impact on Brazilian electrical system. There is a wide range of possible types and methods of frauds, causing enormous difficulties to licensed companies. The objective of this work is to study the problem of NTL using a wide approach, analyze the experience of dealerships in Brazil and abroad, discuss the best practices for mitigation of those losses and propose improvements in the combat and prevention processes, and the legal procedures for recovery of incomes, leaning on a careful regulatory context. This study draws attention to Brazil\'s socioeconomic diversity, comparing it to various international examples, and intends to identify the most relevant aspects that must be considered on the theme, discussing procedures and methodologies for the equation of the amount of resources to be applied by distributing companies to achieve the appropriate reduction of NTL. A large part of the commercial losses has its origin in issues of social stamp. The State owes and can establish policies to solve such issues, making possible the access to electric power supply for all consumers. It was not part of this research to discuss if these instruments are enough, but to analyze the issue of the commercial losses thoroughly based in the regulatory policies that push dealerships to reduce NTL objecting reasonable regular consumers\' tariff.

Повний текст джерелаIn these days, the energy measurement system for residences in urban areas is carried out by eletromechanical meters, which are read manually. Several problems have been observed in this process, which we can emphasize: reading errors, difficulty to access the measurement place, outdated databases, etc. The reading and the measurement automation processes, based in the current eletromechanical meters or with the electronic version of these equipment, besides solving the mentioned problems, have several advantages, such as: minimization of fraud and robbery of energy, implementation of differentiated rates depending on the time of the day (ex:yellow rate), remote energy switch-off and switch-on, implementation of a prepaid system, possibility to get the load curve of each consumer and elimination of error and costs embedded in the manually reading process. On the other hand, we can observe that in Brazil there are an estimated 43 millions residential meters already installed, and the costs for the current measurement system, and also of the meters, are very low. In this scenario, the implementation of a automated system for residential energy measurement is that the proposed system has a very low cost at the same time provides a high reliability. The proposed automation system will consider the reutilization of the current mechanical meters, with the installation of an electronic systems for the consumption data collection, communicating with local concentrators, which in their turn are linked to a computing systems in the energy company. The results of the present work show that, nowadays, there is a real possibility to get, a trustable and cheap automated measurement system for energy in residential urban area. The proposed work is the development of an automated system, for residential energy measurement in urban area. It's composed of a concentrator module for eight residences, with communication from this point to the energy company's operation center. It will be presented a methodology to implement such a system and also a case study.
