Abstract:
This paper aims at investigating the use of an induction wound rotor motor to generate voltage instead of the old diesel engines that are still used in many factories, like old cement factories, in Jordan. In this investigation, a simulation model of induction wound rotor motor was implemented using Matlab/Simulink. The excitation dc current was connected to a two-phase rotor circuit, and the voltage-current performance characteristics were investigated and evaluated under different load types. The simulation results confirmed the possibility of using the induction wound rotor motor as a synchronous generator.

Abstract:
Self-excited induction generators (SEIG) are found to be most suitable candidate for wind energy conversion application required at remote windy locations. The major drawbacks of these generators are the poor voltage and frequency control under load and prime mover speed perturbations. In this paper, an attempt has been made to optimize the control strategy under various load and prime mover conditions, of the self-excited wound rotor induction generator (SEWRIG). By tolerating a slight deviation of the output voltage and ensuring a constant frequency with an adequate external rotor resistance, only four values of excitation capacitor are required for the whole range of operation. The effectiveness of the adopted strategy has been confirmed by comparing on a 0.8-[Formula: see text]kW wound rotor induction generator the simulated results to the corresponding obtained with an experimental test. A close agreement between the computed and experimental results confirms the efficiency of the adopted method.

Abstract:
Eddy currents losses in the rotor in high power generators do not allow operators, under high values of slip, to regulate voltage and control of reactive power flow. The paper presents a method that can accurately estimate the eddy current losses in electric machines with a less complicated procedure. The suggested method allows researchers to analyze and reduce the losses, and consequently, to improve the wind turbine induction generators efficiencies. The given approach, based on the conventional electric machine theory and the parameters supplied by the manufacturers, predicts the eddy current losses theoretically without the need of the measured material loss data or BH curve. Increasing the range of slip variation of induction motor can be achieved by using a rotor of two layers in the radial direction with different parameters. The first layer is a laminated layer of height (h), and the second is a solid (the rotor yoke). The computation of eddy current losses is useful to change the design of the machine to minimize the losses. This paper presents a detailed modeling of the effect parameters on the eddy current losses in wind turbine induction generator.

Abstract:
Accurate online diagnosis of incipient faults and condition assessment on generators is especially challenging to automate through supervised learning techniques, because of data imbalance. Fault-condition training and test data are either not available or are experimentally emulated, and therefore do not precisely account for all the eventualities and nuances of practical operating conditions. Thus, it would be more convenient to harness the ability of unsupervised learning in these applications. An investigation into the use of unsupervised learning as a means of recognizing incipient fault patterns and assessing the condition of a wound-rotor induction generator is presented. High-dimension clustering is performed using stator and rotor current and voltage signatures measured under healthy and varying fault conditions on an experimental wound-rotor induction generator. An analysis and validation of the clustering results are carried out to determine the performance and suitability of the technique. Results indicate that the presented technique can accurately distinguish the different incipient faults investigated in an unsupervised manner. This research will contribute to the ongoing development of unsupervised learning frameworks in data-driven diagnostic systems for WRIGs and similar electrical machines.

Devido as preocupações com a redu¸c¿ao do uso dos recursos f'osseis e das emiss¿oes de CO2 ocasionadas pelos mesmos, o interesse no uso de energias renov 'aveis aumentou, sendo uma destas fontes a energia e'olica. O Gerador de Indu¸c¿ao de Rotor Bobinado (GIRB) tem demonstrado ser uma ferramenta capaz de otimizar o uso da energia e'olica, dada a sua alta efici¿encia, rentabilidade e robustez mec¿anica, ainda assim 'e necess'ario superar os numerosos desafios que est¿ao presentes nesta tecnologia, tais como qualidade da pot¿encia, estabilidade da rede, entre outros. O objetivo desta pesquisa se concentra no estudo de t'ecnicas de controle de pot¿encia fornecida pelo GIRB aplicado a sistemas de gera¸c¿ao e'olica. No presente caso, o sistema de gera¸c¿ao 'e composto por um GIRB com seu estator conectado diretamente 'a rede e seu rotor 'e conectado 'a rede atrav'es de um conversor bidirecional.

Due to concerns about reducing the use of fossil resources and the CO2 emissions caused by them, interest in the use of renewable energy increased, one of these sources is wind energy. The Wound Rotor Induction Generator (WRIG) has been proved to be a tool to optimize the use of wind energy, given its high efficiency, profitability and mechanical robustness, it is still necessary to overcome the many challenges that are present in this technology, such as power quality, grid stability, among others. This research focuses on the study of control techniques for power supply by WRIG applied to wind generation systems. In this case, the generation system consists of a stator WRIG is connected directly to the electrical network and its rotor too, but via a bidirectional converter. It is proposed to study the method of direct torque control (DTC) with the use of PI and sliding mode controllers (SMC) more PI. The direct torque control is a technique of high dynamic performance and enables independent control of torque and flux generator, which will enable the control of active and reactive power ofWRIG. Likewise, it is studied the converter for processing the generated power. The simulations based on mathematical models of these control methods were reviewed , analyzed and compared with simulations of reference texts . Experimental results obtained on a bench validated the proposed prototype.

Abstract:
Sensorless speed estimation in induction machines (IMs) presents an attractive proposition for eliminating the need for physical speed measurement sensors and thus avoiding the associated reliability and cost issues, such as the requirement of extra wiring, careful mounting, maintenance and adjustment. In this thesis, the feasibility of utilising the stator current and power signals to establish spectral search based (SSB) sensorless speed estimation schemes in wound rotor induction machines (WRIMs) operating in extended slip and open-loop controlled conditions is investigated. The research is performed on three different industrial WRIM designs. The thesis first investigates the spectral content of WRIM electrical and mechanical signals with the principal aim of identifying spectral patterns that can facilitate the development of real-time sensorless speed estimation. The examination is based on detailed harmonic models of the considered machine designs as well as experimental results obtained from tests performed on laboratory test rigs. A generalised theoretical analysis of the possible spectral content of machine signals that enables the derivation of closed form analytical expressions linking individual spectral frequencies to rotor speed is also undertaken. The results demonstrate that it is possible to clearly identify speed dependent components in the stator current and power signals and map the boundaries of the narrowbands maximised by these for extended slip and open-loop operating conditions. To enable improvement in attainable real time SSB estimation rates a dichotomous search algorithm real-time spectral processing method was employed for frequency tracking in this research. The algorithm performance is evaluated in real-time tests performed on a measured steady-state laboratory machine stator current and power signals. The results demonstrate that the dichotomous routine provides an inherent advantage in the frequency estimation rate without compromising the estimation accuracy and can therefore enable significant estimation rate improvement in SSB speed estimation algorithms. Novel sensorless speed SSB estimation techniques are then proposed for WRIM operation in extended slip and voltage/frequency controlled conditions. The algorithms utilise the reported analysis of electrical signals and are separately defined for each assessed operation mode and the stator current, phase power and three-phase power signals. It is shown that, in principle, power signal based estimation algorithms can offer an inherent capability of estimation rate reduction. A novel adaptive sliding window algorithm is defined for open-loop operating conditions that enable estimation in a wide operating speed range while minimising the potential for undesirable overlap with PWM harmonics. The proposed algorithms have been verified and their performance limitations assessed in real-time experiments on three different industrial WRIM designs. It is shown that reliable real-time speed estimation in steady-state and transient operating conditions is possible at an improved estimation rate while maintaining a low estimation error.

Abstract:
En esta Tesis ha sido analizado el control de la màquina sincrónica de rotor bobinado actuando en isla. Para esta configuración, la velocidad mecànica determina la frecuencia, y la tensión de rotor se utiliza para fijar la amplitud de la tensión de estator. Debido a que la constante de tiempo eléctrica es mucho más ràpida comparada con la constante de tiempo mecánica, la velocidad mecánica fue considerada constante y externamente regulada y la investigación se enfocó en la regulación de la amplitud de la tensión de estator.

Cuatro diferentes controladores basados en técnicas de modos deslizantes fueron diseñados en el marco de referencia dq. Las leyes de control obtenidas regulan la amplitud de la tensión de estator independientemte del valor de la carga. Adicionalmente, sólo las medidas de tensión y posición del rotor (para calcular la transformada dq) son necesarias. La estabilidad de los puntos de equilibrio obtenidos fueron probados al menos utilizando anàlisis de pequeña señal.

Se realizó la validación por simulación y experimental de cada controlador en diferentes escenarios. Los resultados obtenidos validan los diseños y muestran las principales ventajas y desventajas de el sistema en lazo cerrado.

El capítulo 2 cubre los problemas de modelado de la màquina sincrónica de rotor bobinado. Partiendo de las ecuaciones trifásicas generales, y utilizando la transformada de Park, se encontraron el modelo en dq del generador sincrónico de rotor bobinado (WRSG) en isla, alimentando tanto carga resistiva como inductiva. Los puntos de equilibrio del sistema obtenido fueron analizados y calculados, luego se definió el objetivo de control. Finalmente, se obtuvieron modelos lineales aproximados y sus respectivas funciones de transferencia.

Los controladores PI son los más usados en la industria porque ofrecen buen desempeño y son sencillos de implementar. En el capítulo 3, se obtuvieron las reglas de sintonización para el controlador PI, y se analizaron estos resultados con el objetivo de proponer nuevos controladores que mejoraran el desempeño de la clásica aproximación PI.

El esquema de control en modos deslizantes para la WRSG conectada a una carga resistiva fue diseñado en el capítulo 4. Éste, también incluye un completo análisis de estabilidad del sistema en lazo cerrado.

El capítulo 5 presenta dos diseños basados en modos deslizantes para regular la amplitud de la tensión de estator para el WRSG actuando en isla. Ambos diseños usan la componente d de la tensión de estator en la función de conmutación. El primer caso es un control anidado, donde un lazo externo PI es añadido para proveer la referencia de la componente d de la tensión. En la segunda aproximación un término integral es añadido a la superficie de conmutación.

El caso de alimentar una carga inductiva es estudiado en el capítulo 6. El controlador requiere una extensión dinámica debido a que la amplitud de la tensión de estator es una salida de grado relativo cero. Como resultado, un controlador robusto, que no depende de los parámetros de la máquina ni de los valores de carga es obtenido.

En el capítulo 7 los resultados de simulación y experimentales para los controladores diseñados para el WRSG actuando en isla son presentados. En primer lugar, una descripción completa del banco es presentada. Esta incluye detalles de la etapa de adquisición de datos y de la DSP utilizada. En segundo lugar, se hace la descripción del procedimiento de simulación. Luego, las simulaciones y experimentos, que contienen diferentes escenarios, con cambios de referencia y variaciones de carga para cada controlador son presentados.
The control of the stand-alone the wound rotor synchronous generator has been analyzed in this dissertation. For this islanded configuration, the mechanical speed determines the frequency, and the rotor voltage is used to set the stator voltage amplitude. Due to the electrical time constant is so fast compared with the mechanical time constants, the mechanical speed was considered constant and externally regulated and the research was focused on the stator voltage amplitude regulation.

Four different controllers based on sliding mode control techniques were designed in the dq reference frame. The obtained control laws regulate the stator voltage amplitude irrespectively of the load value. Furthermore, only voltage and rotor position measures (to compute the dq transformation), are required. The stability of the obtained equilibrium points was proved at least using small-signal analysis.

Simulation and experimental validation of each controller containing several scenarios were carried out. The obtained results validate the designs and show the main advantages and disadvantages of each closed loop system.

Chapter 2 covers the modeling issues of the wound rotor synchronous machine. From the general three-phase dynamical equations, and using the Park transformation, the dq-model of the stand-alone wound rotor synchronous generator feeding both a resistive and an inductive load are obtained. Equilibrium points of the obtained systems are analyzed and, after defining the control objective, the desired equilibrium points are computed.
Finally, linear approximated models are obtained and their transfer functions are also presented.

PI controllers are the most used in the industry because they offers good performance and are easily implementables. In Chapter 3 we obtain the tuning rule for the PI controller, and we analyze these results in order to propose new controllers which improve the classic PI approach.

The sliding mode control scheme for the WRSG connected to a resistive load is designed in Chapter 4. It also includes a complete stability analysis of the closed loop system.

Chapter 5 presents two sliding mode designs to regulate the stator voltage amplitude for a stand-alone wound rotor synchronous generator. Both use the stator voltage d-component error in the switching function. The first case is a nested controller, where an outer PI loop is added to provide the proper d-voltage component reference. In the second approach an integral term is added to the switching function.

The case of feeding an inductive load is studied in Chapter 6. The controller introduces a dynamic extension because the stator voltage amplitude is a zero relative degree output. As result, a robust controller, which neither depends on the machine parameters nor on the load values, is obtained.

In Chapter 7 the simulation and the experimental results of the designed controllers for the stand-alone wound rotor synchronous generator are presented. Firstly, a complete description of the bench is provided. It also includes details of the data acquisition stage and the used DSP card. Secondly, the description of the simulation procedure is commented. Then, the simulation and experiments which contains several scenarios, with reference change and load variations evaluated for each controller are presented.

Abstract:
Comumente, as máquinas de indução são projetadas para atuarem como motores. Assim, a presente tese objetiva estudar, analisar e construir um protótipo de máquina de indução concebida para atuar, exclusivamente, como gerador de indução, ou seja, impulsionada acima da velocidade síncrona. As características operacionais ideais em regime permanente são elaboradas intentando diretrizes de projeto. Concomitantemente, o estudo apresenta e investiga modelagens analíticas obtidas por parâmetros concentrados e, também, modelagens numéricas realizadas pelo método dos elementos finitos. Para isto, um gerador de indução trifásico de 2,2 kW tem o rotor do tipo gaiola de esquilo com ranhuras assimétricas projetado e prototipado. O protótipo do gerador de indução visa melhores características de desempenho como o fator de potência e menores perdas, por exemplo, que uma máquina de indução de mesma potência projetada para atuar como motor, mas funcionando como gerador interligado à rede em regime permanente. Os resultados analíticos, numéricos e experimentais em regime permanente do protótipo do gerador de indução e de um motor de indução de mesma potência, mas funcionando como gerador interligado à rede, são apresentados e comparados. Os resultados experimentais obtidos mostram valores nominais de 0,77 e 83,04% de fator de potência e rendimento, respectivamente, para o funcionamento da máquina convencional no ponto de operação próximo ao valor de corrente nominal. Para a máquina de indução projetada como gerador, os valores nominais de 0,82 e 81,35% de fator de potência e rendimento, respectivamente, foram obtidos no ponto de operação próximo ao valor de corrente nominal.
Commonly, induction machines are designed to act as motors. Thus, the present thesis aims to study, analyze and build a prototype of an induction machine designed to work exclusively as induction generator, i.e. driven above synchronous speed. The optimal steady state operating characteristics are elaborated by bringing design guidelines. Concomitantly, this study investigates and presents analytical modeling obtained by lumped parameters and also numerical modeling carried out by the finite element method. Thus, a three-phase squirrel cage induction generator of 2.2 kW with asymmetric rotor slots has designed and prototyped. The prototype of the induction generator aims best performance characteristics such as power factor, for example, than an induction machine of the same power designed to act as a motor, but functioning as generator parallel with the grid. Analytical, numerical and experimental results in steady state operation of the induction generator prototype and of an induction motor of the same power, but functioning as generator parallel with the grid, are presented and compared. The experimental results show nominal values 0.77 and 83.04% of power factor and efficiency, respectively, for the conventional machine in the operating point close to the value of rated current. For the induction machine designed as a generator, the nominal values 0.82 and 81.35% of power factor and efficiency, respectively, were obtained in the operating point close to the value of rated current.

Abstract:
This thesis investigates a novel induction machine topology that uses a rotating power electronic converter. Steady-state and dynamic performance of the topology is studied to understand its operational principle. Furthermore the potential of improving its efficiency and power factor is investigated. The topology is referred to as wound rotor induction machine with rotating power electronic converter (WRIM-RPEC).     The WRIM-RPEC topology offers the possibility to magnetize the induction machine from the rotor side by introducing a reactive voltage in the rotor. Thus, the power factor of the machine can be improved. Constant speed variable load operation can be achieved by setting the frequency of the introduced voltage. Two options of rotor winding and converter configuration in the WRIM-RPEC system are investigated. The wound rotor windings can either be open-ended and fed by a three-phase back-to-back converter or Y-connected and fed by a single three-phase converter. The dc-link in both converter configurations contains only a floating capacitor. These two configurations give different dc-link voltages at the same torque and speed.     Two analytical steady-state models of the topology are developed in this thesis. The first model can be used to analyze the operating condition of the motor at specific speed and torque. Particularly, the operating range of speed and torque of the topology is investigated. The second model is used to analyze variable power factor operation, including unity power factor operation. Analytical calculations and measurements are carried out on a 4-pole, 1.8kW induction machine and the results are compared.      A dynamic mathematic model is then developed for the WRIM-RPEC system for the back-to-back converter configuration. The mathematic model is then applied in Matlab/Simulink to study the dynamic performance of the system including starting, loading and phase-shifting. The simulation results are compared with measurements on the 4-pole, 1.8kW induction machine. Moreover, the simulation model using the existing Simulink blocks are studied to compare with the results obtained from the mathematic model. Furthermore, the dynamic performance of the WRIM-RPEC system with the single converter configuration is investigated. In addition, harmonic spectra analysis is conducted for the stator and rotor currents.     In the last part of the thesis, efficiency improvement is investigated on the 4-pole induction machine when it is assumed to drive a pump load. It is shown that the efficiency can be further improved by decreasing the rotor resistance. Due to space constraints it is however difficult to decrease the rotor resistance in a 4-pole induction machine. An investigation is thus carried out on a standard 12-pole, 17.5kW squirrel-cage induction machine with inherent low power factor. The cage rotor is redesigned to a wound rotor to enable the connection of converter to the rotor windings. An analytical model is developed to design the wound rotor induction machine. The machine performance from calculations is then compared with FEM simulations with good agreement. The analytical model is further used to design several WRIMs with different dimensions and rotor slot numbers. Power factor and efficiency improvement is then explored for these WRIMs. A promising efficiency increase of 6.8% is shown to be achievable.

Dentre as fontes de energia renováveis utilizadas para geração de energia elétrica a que mais se destaca atualmente e a energia eólica. 0 crescente índice de penetração da geração eólica na matriz energética dos sistemas de potencia impõe a necessidade da revisão de conceitos anteriormente estabelecidos sobre a estabilidade de sistemas de potencia, uma vez que ainda não e perfeitamente compreendida a influencia de uma maior integração deste recurso no comportamento dos sistemas de potencia. Este trabalho tem como foco o estudo da estabilidade de sistemas com aerogeradores de velocidade fixa equipados com geradores de indução de rotor em gaiola. E estudada a estabilidade angular de um sistema de geração eólica equipado com aerogeradores desta natureza. O problema da estabilidade foi decomposto em três partes: estabilidade estática, estabilidade dinâmica e estabilidade transitória. São definidos os modelos dos componentes do aerogerador para cada um dos estudos realizados. A topologia adotada á a máquina Barramento Infinito (MBI), na qual o restante do sistema de potência a representado pelo seu equivalente de Thevenin. Esta topologia típica de analise de estabilidade de sistemas de potencia e adotada por permitir a obtenção de resultados analíticos para as analises estática e dinâmica. A analise transitória se dá através de simulações computacionais. A fim de manter um caráter mais geral para os resultados as simulações são realizados com três aerogeradores de características distintas. Os resultados obtidos permitem uma melhor compreensão da influencia sobre a estabilidade do sistema de geração eólica dos parâmetros de rede do sistema de potencia como: potencia de curto-circuito do ponto de conexão comum com o sistema de potencia, relação X/R da linha de transmissão e do capacitor de compensação de fator de potencia.
Among the renewable energy sources used to generate electric power one of the most important at this time is the wind power. The growing penetration index of wind power in the power systems energetic matrix leads to the necessity of a reevaluation of the concepts previously established about the stability of power systems, since the influence of a major integration of this resource in the behavior of power systems is not perfectly understood. This work focuses on the stability study of wind power systems equiped with fixed-speed squirrel-cage induction generators. The angular stability of a wind generation system equipped with wind generators of this nature is studied. The stability problem was decomposed in three parts: static stability, dynamic stability and transient stability. The models of the components of the wind generator are defined for each of the studies. The considered topology was an Induction Generator Infinite Bus System (IBM), where the rest of the power system is represented by it’s Thévenin equivalent. This is a typical topology in power systems stability analysis and is adopted in this work aiming at obtaining analytical and general stability results. The transient analysis is performed by computer simulations. In order to provide more generatily to the stability results, all simulations are conducted with three wind generators with distinct characteristics. The obtained results allow a better comprehension about the influence, on the stability of wind power systems, of power system network parameters as: short-circuit capacity of the common connection point with the power system, the X/R relation of the transmission line and the power factor compensation capacitor.

Abstract:
Le Cambodge est un pays situé en Asie du Sud-Est, avec grand potentiel de ressources en énergies renouvelables. Même fort de ce potentiel, la puissance électrique actuellement installée n'est pas suffisante pour tout le pays. Environ 80% de la population vit dans les zones rurales et 75% des ménages sont sans réseau électrique. Ils utilisent une batterie, le moteur diesel, des bougies ou du kérosène pour l'éclairage, la télévision, les multimédia et autres appareils ménagers. Une minorité des citoyens, dans la partie nord utilise des modules pico hydro électriques acheté dans les pays voisins pour éclairage. Mais la tension de sortie et la fréquence ne sont pas vraiment stables en cas de modification de la charge ou de la vitesse de rotation de la turbine. La durée de vie des appareils électroménagers peut ainsi être réduite et des réparations locales sont nécessaires. Des millions de Cambodgiens ne peuvent pas accéder à l'énergie électrique en raison de deux facteurs principaux : les barrières technologiques et les coûts d'investissement élevés. Nos activités de recherche visent à éliminer ces barrières technologiques en concevant des systèmes de production d'énergie pico-hydroélectrique avec une installation rapide et peu coûteuse, simple et adaptée à une application locale tout en gardant une qualité de l'alimentation électrique satisfaisante. La première partie de cet ouvrage décrit la situation de l'énergie dans les zones rurales du Cambodge où les gens sont confrontés à un manque d'alimentation électrique. En conséquence, ils ne peuvent ni améliorer leur niveau de vie, ni développer leur communauté. Les villageois riches utilisent une batterie de voiture, des systèmes photovoltaïques ou pico-hydroélectriques alors que les villageois pauvres utilisent des bougies ou du kérosène pour l'éclairage. Des entreprises locales fournissent des solutions électriques basées sur des énergies renouvelables, mais les prix sont inabordables et loin de leurs attentes. Par conséquent, une solution originale est proposée dans cette thèse avec la récupération de composants électriques d'occasion en vue de la mise en œuvre d'un nouveau système de génération d'électricité pour les zones rurales isolées. Il s'agit ici d'innovation frugale pour le bas de la pyramide sociale. Les composants utilisés sont : machine asynchrone, alimentation sans interruption (UPS), alimentation de PC et d'autres équipements électroniques, etc. Ces composants recyclés peuvent être rassemblés pour former ainsi une solution technologique intéressante permettant de délivrer la puissance de sortie nécessaire. La deuxième partie de ce mémoire présente la modélisation de l'étage de puissance de la machine asynchrone triphasée utilisée comme un générateur asynchrone monophasé avec une phase d'excitation et les deux autres phases connectées en série pour alimenter la charge. Cette configuration est nommée 'Excited Induction Generator (EIG)'
Cambodia is a country located in Southeast Asia, with its high potential of renewable energy resource. Even if this country has a high potential for renewable, the installed power is still not high enough to cover the whole country. About 80% of population living in rural areas and 75% of the households live without electricity. They survive by using battery, diesel engine, candle, kerosene for lighting, TV, multimedia and some other household appliances. A few of residents in northern part of the country use pico-hydro power units bought from neighbor countries in order to electrify their houses. In these systems, the output voltage and frequency are not really stable while the load under load or speed variations. Consequently, the lifetime of household appliances could be reduced or the items damaged and local repairs are needed. Moreover, millions of Cambodian people cannot access neither take an advantage from the available energy resources due to two main factors: technology barriers and high investment cost. This research aims to remove technology barriers by designing simple systems for pico-hydro power generation with fast and simple installation, suitable for local applications with high quality of electrical supply. The first part of this work briefly describes the energy situation in rural areas of Cambodia where people are facing the lack of electrical supply which. They cannot neither improve their living standard nor develop their community. Rich villagers use car battery, solar PV applications, pico-hydro power while poor villagers use candle/kerosene for lighting. Local enterprises can provide renewable energy solutions but the prices are unaffordable and far from their expectations. Therefore, an original solution is proposed in this thesis by using wasted electric and electronic equipment (second-life components) to form the new power generation systems for remote rural areas. This is frugal innovation to serve the bottom of the social pyramid. The used components are: induction machine, Uninterrupted Power Supply (UPS), power supply of a computer and other electronic equipment, etc. These wasted components can be arranged together to form a good solution with an interesting output power. The second part of this thesis presents the modelling of the power stage of three-phase induction machine as a single-phase induction generator by using one phase for excitation while the other two phases are connected in series to supply load, named "Excited Induction Generator (EIG)". Capacitor banks are added to EIG for compensating the reactive power. Capacitor values influence poles and zeros locations which are described and analyzed in the root locus according to the parameter variations. The third part of this thesis is devoted to onsite modelling of losses in induction machine. The method should achieve results simply, rapidly, without any prior information on the machine, in order to further integrate this model into energy optimization algorithms. Design of experiments is a good candidate. Experimental models of the total loss (iron loss and rotor copper losses) are proposed for motor operation and generator mode for different machines of different powers. The last part of this thesis describes output voltage/current response for both simulation results and experimental results of the induction generators. Proportional-integral and proportional-resonant controllers are tested. The implementation of closed loop controller is first achieved in an analog circuit and then, with dSPACE/MATLAB Simulink environment

Abstract:
This paper investigates the sensitivity of machine electrical quantities when employed as a means of bearing fault detection in wound rotor induction generators. Bearing failure is the most common failure mode in rotating AC machinery. With the widespread use of wound rotor induction machines in modern wind power generation, achieving effective detection of bearing faults in these machines is becoming increasingly important in order to minimize wind turbine maintenance related downtime. Current signature analysis has been demonstrated to be an effective technique for achieving detection of different fault types in ac machines. However, this technique lacks sensitivity when used for detection of bearing failures and therefore sophisticated post processing techniques have recently been suggested to improve its performance. As an alternative, this paper investigates the sensitivity of a range of machine electrical quantities to bearing faults, with the aim of examining the possibility of achieving improved bearing fault detection based on identifying a clear fault spectral signature. The reported signatures can be subjected potentially to refined processing techniques to further improve fault detection.
