Resumo: A produção de hidrogênio para as células a combustível é um desafio para a ampla disseminação dessa tecnologia. Produzi-lo a partir de fontes renováveis de energia, como o etanol da cana-de-açúcar, é a opção analisada neste trabalho, enfocando principalmente a tecnologia dentro do conceito da geração distribuída de energia elétrica. O objetivo da tese é avaliar a viabilidade técnica e econômica da reforma do etanol para produção de hidrogênio com a qualidade necessária para o uso em uma célula a combustível tipo membrana de troca de prótons (PEMFC). A metodologia utilizada foi o desenvolvimento de um protótipo de geração de energia elétrica baseado em um reformador de etanol e um sistema de purificação de hidrogênio. Os principais dados obtidos nesse experimento foram a eficiência global de conversão do protótipo e a quantidade e qualidade das emissões advindas da operação do mesmo. O reformador de etanol alcançou eficiência de conversão de 69%, produzindo hidrogênio ¿ após o sistema de purificação¿ com nível de monóxido de carbono (CO) inferior a 20 µmol.mol, emissões globais de 460,85 g CO2.kWh-1, 0,812 g CO.kWh-1, 2,416 g CH4.kWh-1, sem emissão de NOx e SOx para uma vazão de entrada de 0,33 mol.etanol.hora-1. Com esses valores, foi realizada a análise da viabilidade técnica e econômica, comparando o protótipo desenvolvido com outras tecnologias de geração de energia elétrica. A análise econômica baseou-se em curvas de aprendizado do comportamento do custo inicial do reformador, calculado em 8.000,00 R$.kW-1, em relação à sua produção acumulada para calcular-se o custo de geração do hidrogênio e da energia elétrica produzida ao acoplar-se o experimento a uma célula a combustível tipo PEMFC com eficiência de conversão elétrica de 45%
Abstract: The hydrogen production for fuel cells is a challenge for wide dissemination of this technology. To produce it from renewable sources of energy, such as sugar cane¿s ethanol, is the option analyzed in this work, focusing mainly the fuel cell technology inside of distributed generation concept. The objective of the thesis is to evaluate the technical and economical feasibility of ethanol reforming for hydrogen production with the necessary quality for use in a proton exchange membrane fuel cell (PEMFC). The methodology used was the development of a power generation prototype based on an ethanol reformer and a hydrogen purification system. The main data obtained in that experiment were the prototype global efficiency conversion and the quantity and quality of emissions resulted from prototype operation . The ethanol reformer reached conversion efficiency of 69%, producing hydrogen - after the purification system ¿ with carbon monoxide (CO) level lower than 20 µmol.mol-1, overall emissions of 460.85 g.CO2.kWh- 1, 0.812 g.CO.kWh-1, 2.416 g.CH4.kWh-1, without emissions of NOx and SOx for a 0.33 mol.ethanol.hour-1 flow inlet. Those values were used for the technical and economical feasibility analysis comparing the prototype with others electric power generation technologies. The economical analysis based on learning curves concept of the reformer initial cost behavior, which was estimated in R$ 8,000.00 /kWe, in relation to its accumulated production to calculate the hydrogen and electric power generation production cost when joining the reformer system to a PEMFC fuel cell with 45% electric efficiency conversion

Full textSummary
This report is about how Chile can find its way towards a sustainable power production. The two major Chilean electric systems are modeled and optimized by a special optimization program for energy systems called MODEST. The model is then altered so that new sustainable energy sources can be put into the system. If these new energy sources are more economically beneficial they will enter the system. The time period that is modeled is the years 2006 to 2010 and the demand for electricity is rising between these years. 7 different scenarios where the terms for fossil fuels and renewable energies are changed in different ways is tested to see what can be done to introduce more sustainable energy into the system. The different changes include tax on carbon dioxide emissions, subsidies for new sustainable energy sources and limits in carbon dioxide emissions. The results show that:
• Taxes are an ineffective way to get more sustainable energy but can work to reduce emissions. The tax could be used to fund subsidies for cleaner energies.
• Subsidies can work to bring in more sustainable energy and if there is a possibility to use the clean development mechanisms available within the Kyoto protocol. Then it does not have to be subsidies but investments from companies in countries that have signed the Kyoto protocol.
• Waste to energy is the most cost effective new energy source, although it is questionable however this is really a renewable energy source. The author thinks that although it might not be renewable it is certainly sustainable within a foreseeable future.
• A natural gas shortage will have serious effects on the system and should be avoided at least until there are enough alternative fuels available. It is therefore important to continue encourage the development of sustainable power sources.
• Carbon dioxide limits could be used in Chile. If they are at reasonable levels they do not need to cost that much and could really help the sustainable energy sources to become more interesting for investors.

Full textAs part of the energy recovery part of the ROMA (Resource Optimization and recovery in the Materials industry) project, a laboratory prototype power production system is being built and completed in 2009. The laboratory prototype is based on a new technology for power production from low to medium temperature heat sources (the off gas from electrolysis cells in the aluminum industry) where CO2 is used as a working medium in a trans-critical Rankine cycle. The laboratory rig consists of the power cycle with a prototype expander as the core unit, an air loop to provide the heat, and an ethylene glycol loop to provide condensation of the working fluid in the power cycle. As a preparation to the assembling and instrumentation of the prototype rig, a simulation and an uncertainty analysis were conducted for the prototype rig in the autumn of 2008. This report focuses on the continuation of that work by an experimental investigation of the individual loops and the components of the prototype rig. The emphasis of this investigation has been put on the air loop and the expander unit of the power cycle. This is basically because these are of great importance to the performance of the power production prototype rig. The air loop was thoroughly tested, and from the investigations it was discovered that there was an unfavorable temperature distribution of the air going into the air-to-CO2 heat exchanger. This is the heat exchanger where heat is provided to the power cycle. The source for this temperature maldistribution was identified, and solutions were investigated to improve on the problem without results. The reduced performance of the air loop was incorporated in a new simulation of the power cycle in order to quantify the consequences for the optimization of the power cycle. The simulation was carried out for warm air temperature of 80 °C. The new calculations showed a reduction in maximum net work output of 27 % compared to the original simulation. The optimal conditions for the power cycle were also changed as a consequence of the reduced air loop performance. The investigation of the expander unit revealed that the expander isentropic efficiency was a strong function of the pressure difference across the expander, and a weak function of the expander inlet pressure. It also revealed that overall the isentropic efficiency was much less than the value of 80 % which was used in the original simulation. A new simulation of the power cycle was carried out where the expander isentropic efficiency was incorporated as a function of the pressure difference across the expander. This function was based on the data from the expander testing. The simulation showed a reduction in maximum net work output from 225 W to about 60 W, for warm air temperature of 80 °C. The new expander characteristics also affected the optimization of the power cycle. The simulation results and the results from the prototype investigation will be important in the optimization and control procedures of the assembled prototype power production system.

Full textIn order to guard the system security and quality of supply and retain acceptable levels, a maximum allowed wind power penetration (wind margin) is normally assumed by the operators. Very conservative methods are used to assess the impact of wind power and the consequences turn to under-exploitation of the wind power potential in a given region. This thesis presents the study of actual methods of wind power assessment, divided into three parts:
1. Part I: Impact on the Security of Power Systems
2. Part II: Impact on the Power Quality

Full textPå senare tid har det skett en ökning i antalet solcellsanläggningar som installeras i elnätet och dessa är ofta placerade i distributionsnäten nära hushållen. Eftersom distributionsnäten sällan är dimensionerade för produktion så behöver man utreda effekten av det. I det här arbetet visas det att solcellsproduktion kommer att öka spänningen i elnätet, potentiellt så mycket att de gränser elnätsägarna måste hålla nätet inom överstigs. En modell över lågspänningsnätet skapas i MathWorks MATLAB. Modellen innehåller transformator, kablar, hushåll, energilager och solcellsanläggningar. Systemet simuleras med hjälp av en numerisk Forward Backward Sweep-lösare som beräknar effekter, strömmar och spänningar i elnätet. Solcellanläggningarna placeras ut i elnätet i olika konfigurationer tillsammans med olika konfigurationer av energilager. Resultaten från simuleringarna analyseras främst med avseende på spänningen i elnätet utifrån dess gränser. De slutsatser som dras i arbetet är att solcellsproduktion kommer att påverka spänningen, mycket beroende på var i elnätet anläggningarna placeras och storleken hos dem. Det visas också att energilager, justering av effektfaktor hos solcellsanläggningarna eller en spänningssänkning på transformatorns lågspänningssida kan få ner spänningen i elnätet.

Full textWhen lightning strikes a building in a Power Generation Center, dangerous currents propagates through all the components connected to the building structure: The walls, the grounding grid, and the cables leaving the building. It is the interest of this work to study the transient voltages at the terminations of these cables external to the building.Particularly, the Instrumentation and Measure (IM) cables, since they are connected to electronic equipment susceptible of damage or malfunctioning due to lightning ElectroMagnetic perturbations. A full wave approach based on the numerical solution of Maxwell’s equations through the FDTD algorithm is adopted. Notably, the formalism of Holland and Simpson is used to model all the structures composed of thin wires: the building steel structure, the grounding copper grid, the concrete cable ducts and the coaxial IM cables. A validation of the model developed for each component is presented. A sensitivity analysis is performed in order to the determine the main parameters that configure the problem. Also, the Design of Experiments (DoE) technique is used to generate a meta-model that predicts the peak induced voltages in the cable terminations, as a function of the main parameters that configure the industrial site. This represents an accurate, and computationally efficient tool to assess lightning performance of IM cables

Full textGreen hydrogen is emerging as a powerful solution for the storage of surplus electricity which is generated through renewable energy sources. However, a green hydrogen power cell involves multiphysics phenomena as electrical, fluidic, thermal, etc. and the representation of dynamical power flows therein is quite complex. Furthermore, the power exchange between the different components of the cell (Fuel cell, Electrolyzer, storage units, renewable sources) needs to be thought in terms of global performance while taking care of the energy reserves.This thesis proposes a Bond Graph derived port-Hamiltonian representation of all the components of a green hydrogen power cell. From this representation, it is possible to design passivity-based control algorithms. The notion of passivity margin is introduced to account for the robustness with respect to modeling uncertainties or known disturbances. For each component, the excess or shortage of power feeds an Energy Tank, which behaves as a virtual storage unit. Hence, the set of Energy Tanks is an image of the power reserves in the power cell. Instead of using conventional power routing between each component, we propose to manage power flows between the Energy Tanks, which allows us to control not only the power intensity, but also the level of energy within the tanks. Hence, the methodology enables to control both power and energy at the same time, paving the way to Operating Mode Management triggered by energy levels. An application is given on a platform including a fuel call, renewable energy sources, and a conventional storage unit

O presente trabalho divide-se em dois estudos: uma análise global de sistemas de cogeração e uma modelagem de um ciclo de refrigeração por absorção. O primeiro estudo apresenta as equações dos balanços energéticos de um sistema de cogeração operando com dois motores térmicos distintos (turbina a gás e motor de combustão interna, ambos utilizando diesel como combustível). Para a produção de frio emprega-se um chiller de absorção, acionado a partir de calor de rejeito dos motores, e outro de compressão de vapor auxiliar. As equações de balanço de energia e de exergia, aplicadas a cada componente, formam um sistema não linear de equações que, resolvido, fornece o desempenho do sistema para diferentes condições de operação. O segundo estudo é parte de um projeto mais abrangente, destinado a desenvolver a tecnologia de um sistema de refrigeração por absorção. É apresentado o modelo matemático que caracteriza uma instalação de pequeno porte operando com uma mistura água-amônia. Foram aplicadas as equações de conservação de massa e energia para cada componente do ciclo, determinadas as propriedades termodinâmicas em cada ponto do ciclo e aplicadas hipóteses simplificadoras de modo a descrever matematicamente os processos físicos envolvidos. O modelo resultante foi aplicado a um sistema existente. A comparação entre os resultados previstos pelo modelo e os obtidos experimentalmente foi satisfatória. Uma vez implementados os modelos de ambos os estudos, realizaram-se simulações para casos particulares de operação, possibilitando a verificação da influência das principais variáveis sobre o desempenho dos sistemas analisados. Na solução dos modelos matemáticos foi utilizado o software EES.
The present work embodies two studies: a global analysis of cogeneration systems and an absorption refrigeration cycle model. The first study presents the main equations for energy and exergy balances of a cogeneration system operating with two distinct prime movers (a gas turbine and an internal combustion engine, both powered by diesel oil). For cooling production, an absorption chiller, driven by the prime movers` waste heat, and an auxiliary vapor compression chiller are employed. The energy and exergy balance equations were applied to each component of the system, composing a non-linear system of algebraic equations whose solution provides the performance of the system under different operating conditions. The second study is part of a broader project aiming at the development of an absorption refrigeration system. A mathematical model is presented, describing a small-size absorption refrigeration installation employing a water-ammonia mixture as working fluid. Mass and energy conservation equations were applied to each component of the cycle. Thermodynamic properties of the working fluids were calculated at each point of the cycle. Also, simplifying assumptions were applied. The resulting model was applied to simulate the behavior of an existing system. Comparison of predicted results with experimental data was satisfactory. A parametric analysis was also carried out with the simulation model. The models of both studies were implemented in ESSA software. Simulations were carried out so as to analyze the systems under particular operational conditions and to assess the influence of the main variables on system performance.

Titanium and its alloys are among the most important advanced materials in use today due to attractive properties such as high strength to weight ratio and excellent corrosion resistance. However, the cost of titanium production is high, mostly due to the high cost of extraction. This has led to investigations of potentially lower cost methods such as near-net shape powder metallurgy techniques. One approach, which has the potential of producing the lowest cost powder available, involves converting titanium waste machine turnings to powder using the hydride-dehydride (HDH) process.
