Full textThis study sought to identify the feasibility of utilizing a radioisotope thermal (thermoelectric/stirling) generator to provide power to a deployed USMC Expeditionary Force. The conceptual system architecture was constructed through use of the systems engineering process, identifying necessary subsystems and integration boundaries. Radioisotope comparison was then performed, utilizing weighted design factors. It was determined that Sr-90, Cs-137, and Cm-244 would be the most effective fuel sources for this mission area. By analyzing current thermoelectric technology, it was determined that maximum system efficiency is limited to 1015 percent when utilizing available lead telluride thermoelectrics. Barriers to development of identified physical subsystem components were then identified, including health and environmental hazards of potential isotopes, as well as shielding criteria. The system development was found to be feasible and additional design work and development work is proposed.

Full textNuclear power is the next enabling technology in manned exploration of the solar system. Scientists and engineers continue to design multi-megawatt power systems, yet no power system in the 100 kilowatt, electric, range has been built and flown. Technology demonstrations and studies leave a myriad of systems from which decision makers can choose to build the first manned space nuclear power system. While many subsystem engineers plan in parallel, an accurate specific mass value becomes an important design specification, which is still uncertain. This thesis goes through the design features of the manned Mars mission, its power system requirements, their design attributes as well as their design faults. Specific mass is calculated statistically as well as empirically for 1-15MWe systems. Conclusions are presented on each subsystem as well as recommendations for decision makers on where development needs to begin today in order for the mission to launch in the future.

Full textRenewable energy, electricity and smart grids are core subjects as they have great environmental and societal impacts. Thus, generating, transporting and managing electric energy, i.e., power, still continue to drive a growing interest. In order to properly achieve these goals, several locks must be removed. Beyond issues related to the distribution architecture, the formalization of models, sizing tools, features and indicators, constraints and criteria, decentralized generation and energy management, power quality is central for the whole grid’s reliability. Disturbances affect the power quality and can cause serious impact on other equipment connected to the grid. The work of this thesis is part of this context and focuses on the development of models, indicators, and signal processing methods for power quality monitoring in time-varying power distribution systems.This thesis analyzes the power quality including several well-known features and their relevance. Power system models and signal processing methods for estimating their parameters are investigated for the purpose of real-time monitoring, diagnostic and control tasks under various operating conditions. Among all, the fundamental frequency is one of the most important parameters of a power distribution system. Indeed, its value which is supposed to be a constant varies continuously and reflects the dynamic availability of electric power. The fundamental frequency can also be affected by renewable energy generation and by nasty synchronization of some devices. Moreover, the power absorbed by loads or produced by sources is generally different from one phase to the other one. Obviously, most of the existing residential and industrial electrical installations with several phases work under unbalanced conditions. Identifying the symmetrical components is therefore an efficient way to quantify the imbalance between the phases of a grid. New state-space representations of power systems are proposed for estimating the fundamental frequency and for identifying the voltage symmetrical components of unbalanced three-phase power systems. A first state-space representation is developed by supposing the fundamental frequency to be known or to be calculated by another estimator. In return, it provides other parameters and characteristics from the power system. Another original state-space model is introduced which does not require the fundamental frequency. Here, one state variable is a function of the frequency which can thus be deduced. Furthermore this new state-space model is perfectly are able to represent a three-phase power system in both balanced and unbalanced conditions. This not the case of lots of existing models. The advantage of the proposed state-space representation is that it gives directly access to physical parameters of the system, like the frequency and the amplitude and phase values of the voltage symmetrical components. Power systems parameters can thus be estimated in real-time by using the new state-space with an online estimation process like an Extended Kalman Filter (EKF). The digital implementation of the proposed methods presents small computational requirement, elegant recursive properties, and optimal estimations with Gaussian error statistics.The methods have been implemented and validated through various tests respecting real technical constraints and operating conditions. The methods can be integrated in active power filtering schemes or load-frequency control strategies to monitor power systems and to compensate for electrical disturbances

Full textThe Intergalactic Medium (IGM), by means the Lyα absorption in quasar spectra ( this is called Lyα forest), is a unique tool allowing the study of the large scales of the universe, which in this way constrains several cosmological, the growth factor of the structure. Moreover the IGM also plays primordial role in galaxy formation. Understanding the physics of the IGM and the way non-linear processes affect the observed Lyα forest, hydrodynamical simulations are necessary because the non linear evolution of the physics cannot be treated in any analytic framework. At the same time, a large number of observations, which have been obtained from the Barionic Oscilation Spectrographic survey (BOSS) to be used in thesis allow studding in unprecedented large number of Lyα forest from quasar spectra, allowing to achieve major breakthroughs. In the 2nd chapter of this thesis we describe the methodology that we developed to extract the power spectrum from the transmission flux of the Hydrodynamical simulations. Using a set of simulations provided by various collaborators we study the effects of various simulation characteristics, such as resolution, box size, particles, and cell division, to see how they might affect the extracted power spectrum. Then we proceed to develop a model to fit the power spectrum of each of the simulations and in this way see the effects of different simulation and physical properties on the predictions from the power spectrum. Once the model fit has been obtained, the non linear power spectrum of the transmission can be related on the matter power spectrum, which on the form of its biased relation with the matter power spectrum contains the cosmological information. This relation is measured by the bias and redshift distortions that can be directly measured from simulations, making predictions for these values that could be later tested with the observations. In the 3rd chapter we use the data from the large catalogue of Damped Lyα systems (DLAs) provided by BOSS. These DLAs, broad regions of completely absorbed flux in the spectra of about 10% of the high redshift objects, the quasars. The DLAs are a large repository of neutral hydrogen, that is why they absorb all the flux that corresponds to their redshift. Since there is so much Neutral Hydrogen the absorption is damped, meaning that wavelength close to the one of the DLA also get absorbed, forming characteristic Lorenz wings that are sensitive to the column density of Hydrogen of the DLA. DLAs are interesting objects that are expected to be very relevant for galaxy formation, and also because they trace the large structure, therefore also being relevant for cosmology. They are, similarly to IGM of which they form part, a bridge between the large cosmological framework and the galaxies that populate the universe. The BOSS survey has allowed us for the first time have a set of thousands of DLAs. Given this amount of data and the interest of the DLAs, we developed a new method and a new parameterization to study the DLAs in the framework of large surveys such as BOSS. First we constructed a method to measure the equivalent width of several metal absorption lines associated with each DLA, even if individually they are not detected because they can not be observed due to the noise and resolution of the spectrum. The equivalent width are combined in a newly defined parameter called Metal Strength, which is a an optimal combination of the equivalent width of the metals measured for a DLA. This classification can then have many applications to measure the mean stack, mean bias and mean redshift evolution with respect this new parameter. The Metal Strength is therefore used to analyse the evolution and characteristics of the various populations of DLAs.

Resumo: Uma metodologia alternativa e aprimorada para modelagem de linhas de transmissão multifásicas é apresentada ao longo do desenvolvimento proposto. O desacoplamento modal das fases e cabos pára-raios dá-se por meio de uma metodologia otimizada no uso das matrizes de transformação modal ao longo das sucessivas transformações entre os domínios dos modos e das fases, eliminando os erros decorrentes da modelagem e representação da linha fazendo uso de análise modal. A representação equivalente de cada modo de propagação é desenvolvida por elementos discretos convencionais com base na teoria fundamental de circuitos elétricos, o que torna a modelagem em questão simplificada, porém não menos precisa. Para modelagem do efeito da frequência nos parâmetros longitudinais da linha, é utilizado vector fitting para sintetizar os parâmetros de forma equivalente e por elementos discretos para cada modo de propagação do sistema multifásico. O sistema de equações diferenciais é representado no espaço de estados e facilmente solucionado por métodos numéricos de integração. No entanto, propõe-se a resolução do sistema de equações de estado por meio de um método de solução analítico, significativamente mais eficaz computacionalmente e mais robusto que o método de integração trapezoidal, amplamente aplicado na simulação de transitórios eletromagnéticos. Ademais, o método analítico possibilita o desenvolvimento de uma metodologia híbrida, adequada tanto na simulação de fenômenos transitórios quanto na simulação fenômenos em regime permanente. O modelo proposto é totalmente desenvolvido no domínio do tempo, sem a utilização de transformadas inversas e convoluções, tornando simples a integração de outros dispositivos e elementos não lineares ao longo da linha. Por fim, um processo utilizando FIR digital filtering integrado à modelagem por matrizes de estado, elimina todas as oscilações espúrias decorrentes da discretização da linha por elementos discretos e erros de truncamento. Em suma, o modelo computacional proposto apresenta uma metodologia aprimorada que se estender desde a modelagem dos parâmetros elétricos da linha à simulação propriamente dita dos transitórios eletromagnéticos, na ordem de poucos milissegundos, e fenômenos transitórios mais lentos, próximos do sinal fundamental em regime permanente
Abstract: An alternative and accurate methodology to model multiphase transmission lines is presented in the proposed development. The modal decoupling of the phases and shield wires is given by an optimized methodology in the use of the modal transformation matrix through the successive transformations between modal and phase domains, correcting the errors associated with the modeling and representation of the line by using analysis modal. Each propagation mode is represented by conventional lumped elements widely approached in the electrical circuit theory, which simplify the equivalent modeling, although a no less accurate procedure. To insert the frequency dependence of the longitudinal parameters in the line model, the vector fitting is applied to synthesize the parameters by an equivalent lumped circuit for each propagation mode of the multiphase system. The system of differential equations, resulting from the differential equations associated with the modal parameters, is represented in the state space and easily solved by numeric integration methods. Although, an analytical solution method is proposed to solve the system of state equations. This solution method is more efficient in computational terms and more robust than the well-known trapezoidal rule, widely used for simulation of electromagnetic transients. Furthermore, the proposed analytical method enables the development of a hybrid methodology, properly adapted to simulate transients as well as steady-state phenomena. The proposed model is completely developed in the time domain, without the use of inverse transforms and convolutions, which means that the proposed modeling is totally compatible with any other power electrical devices and nonlinear elements modeled in the time domain. Finally, a process using FIR digital filtering integrated to the modeling by state matrices eliminates all the spurious oscillations occurred from the line parameters discretization and truncation errors. In short, the proposed computational model presents an improved methodology carried out since the line electrical parameters modeling up to the simulation of electromagnetic transients of a few microseconds up to slow transient phenomena, close of the steady-state fundamental signal

Full textS'han desenvolupat diversos models que han permès obtenir resultats de simulació de les tècniques de modulació i control proposades. A més, gràcies a l'estada d'un any de l'autor al Center for Power Electronics Systems (CPES) a Virginia Tech, USA, la tesi també inclou resultats experimentals que consoliden les conclusions i metodologies presentades. Les principals contribucions es resumeixen a continuació.
Es presenta un nou algorisme de modulació vectorial PWM que aprofita simetries del diagrama vectorial per a reduir el temps de processat. S'analitzen i es quantifiquen les oscil·lacions de tensió de baixa freqüència que apareixen en el punt central dels condensadors del convertidor de tres nivells. Aquesta informació permet dimensionar els condensadors donades les especificacions d'una determinada aplicació.
L'algorisme de modulació també s'aplica a convertidors de més nivells. Pel cas concret del convertidor de quatre nivells, es comprova l'existència de corrents continus en els punts mitjos dels condensadors que fan que els sistema sigui inestable. Es determinen gràficament les zones d'inestabilitat.
Es presenta un nou i eficient algorisme de modulació vectorial feedforward en el convertidor de tres nivells que és capaç de generar tensions trifàsiques de sortida equilibrades, malgrat l'existència de desequilibris en les tensions dels condensadors.
S'estudien els efectes negatius de càrregues lineals desequilibrades i càrregues no lineals en el control de les tensions dels condensadors. Es justifica que l'existència d'un quart harmònic en els corrents de càrrega pot inestabilitzar el sistema. És determina la màxima amplitud tolerable d'aquest harmònic.
S'estudia la millora en l'equilibrat de les tensions d'una connexió de dos convertidors de tres nivells al mateix bus de continua (back-to-back connection). Un exemple d'aplicació pràctica és la conversió AC/DC/AC per a l'accionament de motors d'alterna treballant amb factor de potència unitari.
Finalment s'aplica un controlador òptim al convertidor de tres nivells treballant com a rectificador elevador (boost). El llaç de control LQR (Linear Quadratic Regulator) es simplifica donat que la tasca d'equilibrat de les tensions dels condensadors es dur a terme en el mateix modulador.
