Orientador: Sinclair Mallet-Guy Guerra / Dissertação (mestrado) - Universidade Estadual de Campinas, Faculdade de Engenharia Mecanica / Made available in DSpace on 2018-08-05T16:57:00Z (GMT). No. of bitstreams: 1 Strazzi_PauloErnesto_M.pdf: 719128 bytes, checksum: e826aa1a4a9320a63a73196b4fe1013e (MD5) Previous issue date: 1998 / Resumo: Neste trabalho foi elaborado o estudo que teve como objetivo estabelecer uma avaliação entre as tarifas praticadas entre 1980-95 e os investimentos nesse mesmo período. Para essa avaliação parte-se do princípio de que as tarifas representam parte da constituição dos fundos necessários à formação dos montantes investidos. Caso esses totais não sejam contemplados com a parcela das tarifas, as empresas concessionárias captarão recursos a partir de lançamentos de títulos no mercado de capitais ou de empréstimos do sistema financeiro. Resultado de tal operação é o aparecimento do endividamento dessas empresas. Para isso, elaborou-se análises estatística através dos valores realizados de tarifas e investimentos entre os anos de 1978 e 1995, com ajustamento dos respectivos valores, sendo assim efetuada uma projeção para os próximos 5 anos com essa base de realização. Esses resultados obtidos, bem como a análise histórica efetuada, traçam uma importante linha de raciocínio para futuros estudos do setor de eletricidade e também na otimização do planejamento produtivo da indústria de eletricidade / Abstract: The study presented here was elaborated with the objective of establishing a comparison between tariffs practiced from 1980 to 1995 and the investments in the same period. This evaluation is based on the principal that the tariffs represent an integral part of the funds necessary for the total investments. If the tariffs are not contemplated as part of the investments, the concessionary companies will raise money placing their stocks for sale or from financial loans. The results of these operations are the rise of the debt. For this, statistical analises were elaborated thru the use of the tariffs and investments practiced between 1978 and 1995, with adjustment of the respective values, having been made a projection for the next 5 years. The results obtained, as well as the historical analyses, redirect an important line of reasoning for future studies in the electrical energy studies and also in the optimization of productive planning of the electrical industry / Mestrado / Energia, Sociedade e Meio Ambiente / Mestre em Engenharia Mecânica

For the case study were selected as spatial area, the River Basin Piquiri and the Paraná Basin 3. These two basins were selected because of the plans for the construction of several SHPs in their covered area. SHPs are considered by energy planners linked to the public sector or private companies as alternative sources of electricity production from low impact to the environment. Nevertheless, if several of them are built in the same river or watershed there may be an impairment of the environment equivalent to the installation of a hydroelectric plant. To better understand the magnitude of this argument, the research focused on the study of examples of cumulative impacts resulting from the construction of several plants in the same basin, already observed in other Brazilian states. It is important to inform that, until the completion of this research was the cropping area of study only one SHP in operation - it is the SHP San Francisco, located on the border of the cities of Toledo and Ouro Verde do Oeste, in the western region of the state Paraná. In order to achieve the proposed objectives were analyzed issues related to SHP such as: laws of the electricity sector and environmental, policies of financial incentives to the sector, as well as programs and projects of incentives for generation of alternative energy in Brazil. Although not operate at wire of water, in other words , do not require large reservoirs, still does not have a effective billing by the environmental agencies of a global study of all the plants on the same river or watershed. The study provided a check on what stage are SHPs existing or planned for the covered area by the two watersheds selected , which resulted in the making of maps that help understanding the topic / A presente pesquisa aborda os impactos socioambientais resultantes da implantação de Pequenas Centrais Hidrelétricas (PCHs) na faixa de fronteira ocidental paranaense. Para o estudo de caso foram selecionadas, como recorte espacial, a Bacia Hidrográfica do Rio Piquiri e a Bacia Hidrográfica do Paraná 3. Estas duas bacias foram selecionadas em razão da previsão de construção de diversas PCHs na sua área de abrangência. As PCHs são consideradas pelos planejadores de energia ligados ao setor público ou de empresas privadas como fontes alternativas de produção de eletricidade de baixo impacto ao meio ambiente. Contudo, caso sejam construídas várias delas em um mesmo rio ou bacia hidrográfica, pode haver um comprometimento do entorno equivalente à instalação de uma usina hidrelétrica. Para entender melhor a dimensão desse argumento, a pesquisa concentrou-se no estudo de exemplos de impactos cumulativos resultantes da construção de várias usinas em uma mesma bacia hidrográfica, já constatados em outros Estados brasileiros. É importante informar que, até a conclusão desta pesquisa, havia na área de recorte de estudo somente uma PCH em operação - trata-se da PCH São Francisco, localizada na divisa dos municípios de Toledo e Ouro Verde do Oeste, na região Oeste do Estado do Paraná. A fim de alcançar os objetivos propostos, foram analisadas questões referentes às PCHs tais como: legislações do setor elétrico e ambiental, políticas de incentivos financeiros ao setor, além de programas e projetos de incentivos à geração de energias alternativas no Brasil. Apesar de não operarem em fio d água, ou seja, não necessitam de grandes reservatórios, ainda não se tem uma cobrança efetiva por parte dos órgãos ambientais de um estudo global de todas as usinas em um mesmo rio ou bacia hidrográfica. O estudo proporcionou a verificação do estágio em que se encontram as PCHs existentes ou previstas para a área de abrangência das duas bacias hidrográficas selecionadas, que resultaram na confecção de mapas que auxiliam a compreensão do tema

Reestruturação e privatização no setor elétrico brasileiro: impactos sobre as relações de trabalho / Reorganization and privatization in the brazilian electric sector: impacts on the labor relations.

Marcia Maria Silveira Campos Moreira 01 December 2006 (has links)
Este trabalho tem como objetivo apontar os impactos que as transformações institucionais do setor elétrico brasileiro tiveram sobre as relações de trabalho. Assim, parte do entendimento das reformas setoriais iniciadas em 1995, com a aprovação da Lei das Privatizações, destacando duas principais ações: a desverticalização das atividades de geração, transmissão, distribuição e comercialização de energia e as privatizações. Entende-se aqui que estas reformas ocorreram em meio a uma crise energética, desencadeada, em especial, pela incapacidade do Estado em investir o montante necessário para garantir a oferta de energia demandada pelo país. Mais do que isto, entende-se que esta reforma institucional do setor elétrico é parte integrante de mudanças mais amplas na concepção do Estado brasileiro, que vem adotando medidas liberalizantes, em especial na área de infra-estrutura do país (energia, telecomunicações, transportes, entre outros). É neste ponto que o trabalho passa a entender as transformações setoriais inseridas no contexto do capitalismo contemporâneo, marcado pelo cenário de competição global. Assim, assiste-se, tanto no cenário nacional quanto internacional, à discussões sobre a revisão dos papéis do Estado, à reestruturações empresariais conduzidas em prol da competitividade e à crise do mundo do trabalho. Esta última é marcada pela queda do nível do emprego, pelo aumento de formas precárias de inserção do trabalhador no mercado de trabalho, pela queda no rendimento e pela dificuldade dos sindicatos em defender o valor da força de trabalho neste novo contexto político, social e econômico. A pesquisa de campo conduzida revela as transformações institucionais do setor elétrico brasileiro causaram impactos negativos sobre os trabalhadores. O nível de emprego caiu 37% e os salários, em média 16% entre os anos de 1995 e 2004, nas atividades de geração e distribuição de energia, mais diretamente afetadas com as privatizações. Neste mesmo período, houve alteração significativa no perfil dos trabalhadores dessas atividades, que passaram a ser mais jovens, com menos tempo de empresa e com melhor grau de instrução. As entrevistas realizadas junto a dirigentes dos sindicatos dos eletricitários de São Paulo e de Campinas revelaram as dificuldades das entidades de representação dos trabalhadores em manter benefícios anteriormente conquistados e de representar trabalhadores que, embora terceirizados, executam atividades relacionadas ao setor elétrico. Já as entrevistas realizadas junto a gestores de recursos humanos de duas importantes distribuidoras de energia elétrica do Estado de São Paulo retrataram os esforços desprendidos nos processos de reestruturação empresarial, que levaram a adoção de novas formas de organização do trabalho e novos modelos de gestão de pessoas, trazendo importantes ganhos de eficiência para as organizações. Assim, de um lado temos os indicadores do lado do trabalho apontando para um cenário de fragilidade, enquanto os indicadores organizacionais apontam para a melhoria do desempenho técnico e financeiro das empresas estudadas. Questiona-se ainda se o modelo institucional adotado pelo setor elétrico, apesar de trazer prejuízos para o campo do trabalho, teve impactos positivos para a sociedade. Neste ponto, alerta-se para o aumento significativo das tarifas de energia, que cresceram 251,9% entre os anos de 1994 e 2004, período em que a inflação foi de 156,5%. Tais conclusões remetem à necessidade de repensar a forma de regulação do Estado sobre os segmentos de infra-estrutura no país, em especial, das concessionárias prestadoras de serviços de utilidade pública, como é o caso das distribuidoras de energia elétrica. / This paper is intended to briefly analyse and point out the consequences of the institutional modifications, recently undergone by the brazilian electric power companies, from the standpoint of labor relationship. Our analysis covers the period beginning in 1995, by the time the Law of Privatizations was passed, and will be mainly focused on the organizational rearrangement of generation, transmission, distribution and power supply activities, and on the privatization implications. It should be initially mentioned that such modifications came about during a serious energy crisis, caused by the lack of financial capacity on the part of the brazilian government, enough to meet power demand throughout the country. Furthermore, it should be understood that those institutional modifications, are only part of a more comprehensive context, involving a new insight of brazilian government standards, with the adoption of a more liberal policy, as applied to the fields of power, telecommunications, transportation, among others. This paper develops its analysis exactly from this point on, so as to include all aspects related to social-economic modifications occurred in those areas, as a consequence of modern capitalism, in a global context. It can be noticed, in both national and international contexts, many discussions going on about the new role of the State, and at the same time, private companies discussing reengineering solutions in order to adjust themselves to a modern highly competitive world and to new labor relationships. Employment levels have permanently decreased and temporary or unstable forms of employment have been offered to the labor market, whereas workers and syndicates have to struggle hard to represent and defend their interests in this new situation A field survey on that was carried out and clearly showed a negative impact of such modifications upon the labor market. Employment and salary levels decreased by 37%, and 16% respectively, as of 1995 through 2004. Power generation and distribution activities were the most affected areas by privatization. At the same time, a significant alteration of personal and professional profiles of the workers in such areas was noticed, with younger, more recently hired and better educated people. All interviews made with syndicate directors, both in São Paulo and in Campinas, have indicated a huge trouble they have to face, when trying to keep fringe benefits previously granted, as well as representing the interest of outsourced workers, that perform the same job of regular ones. On the other hand, interviews that were made with human resources managers of the two most important power companies of São Paulo State, have shown their endeavor towards the reorganization of their companies, by introducing new methodologies, and new people management routines, with a view to improving their efficiency at work. Thus, there is a different scenery, as seen from these two conflicting points of view. Whereas workers and their syndicates, consider themselves weakened for negotiating what they assume to be their rights, their managers are very happy about the meaningful improvement detected on the technical and financial performance of the respective companies. A question comes up on whether or not this institutional model, although supposedly bringing about losses to workers of power companies, has really been positive to consumers and to society as a whole. It should be pointed out that from 1994 through 2004, power supply service fees increased by 251.9%, whereas in the same period the calculated inflation was 156.6%. These numbers probably show the necessity of reconsidering the model for granting public utility services to private groups so as to improve it towards more reasonable results.

No. of bitstreams: 1 Cavalcante_JoseAparecido_M.pdf: 6372683 bytes, checksum: b1a207d1d57ed9915853e751ccf18ea3 (MD5) Previous issue date: 2011 / Resumo: O objetivo deste trabalho é trazer subsídios para o planejamento da integração de sistemas de cogeração, com geração de excedentes de energia elétrica, aos sistemas de suprimento de energia, exemplificando com um estudo de caso na área de concessão da CPFL, no estado de São Paulo. Após analisar a evolução da cogeração no âmbito da CPFL desde 1980 e as tendências mais recentes, e revistos alguns estudos sobre o planejamento da integração de sistemas de cogeração, foram estimados os potenciais "práticos" para 2015, considerado os aumentos de produção no setor de cana de açúcar. Na avaliação desses potenciais foram consideradas restrições de tecnologia, de oferta de matéria prima, e restrições comerciais. A distribuição espacial das unidades industriais do setor foi considerada, e foram incluídas as unidades em fase de instalação. A legislação atual (em rápida mudança) sobre o acesso de cogeradores ao Sistema de Distribuição e Transmissão das Concessionárias foi revista, e um estudo de caso completo baseado em uma solicitação de conexão é apresentado como exemplo. Tendo como exemplo as regiões Noroeste e Nordeste do estado de São Paulo, os mapas de oferta potencial foram sobrepostos aos mapas de demanda regional futura estimada, além de terem sido consideradas as restrições existentes dos sistemas de distribuição e de transmissão. Os resultados desta dissertação são subsídios para o planejamento da expansão da cogeração nos próximos anos. Ao fim, são apresentadas sugestões para futuros estudos no tema / Abstract: The objective was to collect and process information to help in the planning of integration of co-generated surplus electricity from distributed systems with the SIN, with focus in the state of São Paulo, exemplifying with the area of concession of CPFL. After analyzing co-generated energy utilization by CPFL since 1980 and the recent trends, and having considered the last studies on the integration, "practical" potentials were estimated (2015 horizon) for the sector of sugar cane processing. The estimates considered the expected growth for each sector in the period, and restrictions due to technology availability, as well as economic and commercial constraints. The sugar cane sector presents the largest potential than the others, and its space distribution was established including the units in the implementation phase. The legislation and regulations for connection with the distribution systems (changing very rapidly in the last years) are summarized, and a complete Case Study was prepared (analysis of a specific connection required by a potential supplier) as an example, to indicate the main parameters for decision. The information for the expansion planning for the next years is provided (with the sugar cane potential suppliers) adding the mapping of the potential supply from each unit to the maps with estimates of the regional future demand and local projected restrictions (distribution and transmission). Suggestions are presented for advancing the present studies / Mestrado / Mestre em Planejamento de Sistemas Energéticos

Adaptor Development : An insight to interfacing with electrical energy meters

Castberg, Miro January 2011 (has links)
Since energy meters became more advanced and able to send data remotely, energy suppliers have had a need to keep their data managed. This gave birth to energy management systems which gather data from energy meters. However, for every type of meter there needs to be a specialization in the management system. Smart Metering Language (SML) is a protocol which was created to transfer meter data in as simple way as possible. Implementing the protocol would result in simpler and less vendor-specific solutions for energy management systems. This report follows the process of developing an adaptor between a device using the SML protocol and a system that manages energy meters. The thesis uses different parts of the development process in able to show specializations which were needed by the test device and its vendor.  The result sums up the experience of developing an adaptor and the specializations which are needed in the SML protocol.

A tríade energia elétrica, desenvolvimento sustentável e tecnologia - bases e desafios para uma regulação evolutiva no Brasil. / Triad electric energy, sustainable development and technology: bases and challenges for evolutionary regulation in Brazil.

Solange Mendes Geraldo Ragazi David 17 May 2018 (has links)
O futuro da Regulação do setor elétrico, tema central desta Tese, deve ser analisado no contexto da evolução tecnológica e do desenvolvimento sustentável, considerados seus três pilares fundamentais: a economia, o meio ambiente e a sociedade. No século XXI, um dos grandes desafios do setor elétrico mundial é a regulação de temas inseridos no amplo contexto da smart energy, com mais fontes renováveis na matriz, outras formas de atuação do consumidor e novos modelos de negócios. Análises, dados, fatos e evidências empíricas obtidas em pesquisas e apresentadas nesta Tese permitem afirmar que há razões suficientemente consistentes para que se busque uma nova abordagem da Regulação do setor elétrico brasileiro. Assim, é apresentado um novo caminho para a Regulação, consubstanciado numa Engenharia Regulatória, com maior visão sistêmica e prospectiva para tratar das questões da sustentabilidade, da economia verde e da sociedade mais digital e hiperconectada. Nesta Tese são apresentadas duas propostas: (1) premissas para a adoção de uma Regulação Evolutiva e (2) premissas para uma Plataforma Regulatória. Pela Regulação Evolutiva, há uma maneira diferenciada de regular o setor elétrico, caracterizada por tratar de forma mais convergente, dinâmica, equilibrada, interativa e qualificada as demandas da própria sociedade e do mercado, em que o consumidor assume papel mais decisivo como ator na transição para um setor diferenciado (geração distribuída, micro e minigeração, resposta da demanda, smart city, smart grid, smart metering, energy storage, entre outros). A Plataforma Regulatória deve ser uma ferramenta/sistema de suporte para estruturar a informação e auxiliar na adoção de soluções regulatórias, com maior participação, consistência e transparência. A Plataforma Regulatória busca agregar mais valor à inteligência regulatória, com a observação imediata de temas da agenda nacional e mundial, para verificar sua aderência aos temas a serem regulados. O trabalho visa contribuir de forma original para o debate e aprimoramento da Regulação, para atender a essa realidade de interrelação entre a evolução tecnológica e o desenvolvimento sustentável no setor que tende a ser cada vez mais 4D - digitalizado, descarbonizado, descentralizado e democrático. O futuro não deve ser mais o que foi projetado no passado, mas o que se estruturar a partir de uma consciência presente sobre os cenários, tendências e possíveis disrupturas, além da adoção de ações conjuntas na sociedade, entre as quais se inclui a Regulação do setor elétrico. / The future of the regulation of the electricity sector, the central theme of this Thesis, must be analyzed in the context of technological change and sustainable development, considered their three fundamental pillars: the economy, the environment and society. In the 21st Century, one of the great challenges of the world electricity sector is the regulation of themes included in the broad context of the smart energy, with more renewable sources in an array, other forms of consumer activity and new business models. Analysis, data, facts and empirical evidence obtained in research and presented in this Thesis allow to assert that there are consistent reasons to seek out a new approach to the Regulation of the Brazilian Electric Sector. Therefore, a new way to adjust is presented, organized in a Regulatory Engineering, with greater systemic vision and foresight to address the issues of sustainability, green economy and a more digital and hyperconnected society. In this Thesis, there are two proposals: (1) premises for the adoption of an Evolutionary Regulation and (2) premises for a Regulatory Platform. By Evolutionary Regulation, there is a different way to regulate the electricity sector, characterized by treating in a more convergent, dynamic, balanced, interactive and qualified way the demands of the society and the market, in which the consumer assumes a more decisive role as an actor in the transition to a distinguished sector (distributed generation, micro and minigeneration, demand response, smart city, smart grid, smart metering, energy storage, among others). The Regulatory Platform must be a tool/support system for structuring the information and assisting in the adoption of regulatory solutions, with greater participation, consistency and transparency. The Regulatory Platform seeks to add more value to regulatory intelligence, by immeditately observing national and global agenda issues to analyze its adherence to the themes to be regulated. The work aims to contribute to the debate and improvement of the Regulation in an original way, to meet this reality of interrelation between technological progress and sustainable development in the sector, which tends to be more and more 4 D - Digitalized, Decarbonized, Decentralized and Democratic. The future must no longer be what was designed in the past, but what is structured from a present conscience on the scenarios, trends and possible disruptions, in addition to the adoption of joint actions in society, including the Regulation of the electricity sector.

Experimental and numerical analysis of a Pump as Turbine (PaT) in micro Pumped Hydro Energy Storage (μ-PHES)

Morabito, Alessandro 28 June 2021 (has links) (PDF)
In the last decade, the power generation mix and the energy markets have been affected by the growing development of distributed and renewable energy sources.Nevertheless, a significant drawback of solar and wind energy is their intermittent and weather-dependent production, which often leads to a mismatch between renewable energy production and its use. Thus, the need for energy storage is recently emerging and becoming more relevant in this era of the energy transition. Among several technologies, today, pumped hydro energy storage (PHES) represents the largest share of the energy storage systems in the world. However, possible new investors, who might be attracted by potential profit in PHES, are repelled bythe long payback period and the scarcity of adequate site topology for such power plants. Relevant design decisions can be taken to reduce the costs and improve the performance or to escape the PHES topographical requirements. For this reason, the first part of this PhD thesis reviews and provides potential assessments of some unconventional PHES systems, applied in synergy with existing infrastructures. Such is the standpoint of micro facilities near waterway locks, or underground cavities used as lower reservoirs (UPSH), or the use of pump-turbines at variable geometryto cope with fluctuating loads.Moreover, important information on PHES in micro-scale is largely missing and their potential in distributed energy systems still needs to be unveiled. In the attempt to fill this gap, this thesis provides a techno-economic overview of the design and characterization of a first-of-its-kind PHES micro facility. In micro-scales hydropower projects, the initial capital cost of a conventional hydroelectric unit is hard to be determined and often economically prohibitive. Interestingly, in order to cut the total capital investment, the micro-PHES prototype runs with a single centrifugal pump for both pumping and generating phases and exploits existing stormwater reservoirs. The variable speed regulation is also implemented and it allows the pump to constantly operate at the maximum hydraulic efficiency in order to deal with load variations. In the same way, the pump working in reverse, namely pump as turbine (PaT), runs at the most suitable speed and it keeps a high efficiency over a wide load range. In addition, the analysis of the techno-economic parameters for such a system provides an important dataset for micro-PHES feasibility breakdown.PaTs are a legitimate cost-effective option in micro hydropower but an universal performance prediction does not exist. Their hydraulic efficiency can possibly shift from the higher efficiency of traditional hydraulic turbines. Nowadays, these reasons restrict PaTs exploitation. In this thesis, a multivariate regression method is applied to the CFD results to build a surrogate model of the PaT hydraulic characteristics as a function of the cutwater geometrical modifications. Based on this model, an optimization problem is solved to identify the most advantageous geometrical assetof the PaT cutwater to maximize the hydraulic efficiency. The presented methodology and design optimization of the cutwater in PaTs, which are extremely suited to our current energy generation needs, provides a unique and much-sought guide to its performance, improvements, and adaptation to hydropower. / Doctorat en Sciences de l'ingénieur et technologie / info:eu-repo/semantics/nonPublished
