Raisigel, Hynek. "Micro-générateur magnétique planaire et micro-convertisseur intégré." Grenoble INPG, 2006. http://www.theses.fr/2006INPG0193.
Full textThis thesis deals with electric micro-generation and micro-energy management. The developed micro-generator is a millimetre-scale, planar, axial-flux, ironless, permanent magnet, synchronous machine compatible with fast rotating MEMS turbines. Established multiphysical model enables the magnetic generator performance estimation in dependence on its operating point and geometry. A 8mm diameter magnetic micro-generator has been successfully tested to speeds up to 380 000 rpm ; at this speed it generates 5W with an electrical efficiency of 57%. A prototype of a fully integrated micro-turbo-generator generated about 15mV at 60000 rpm. Low power AC/DC micro converters for low voltage micro generators were also studied. A three-phase, high efficiency, low voltage, low power and fully autonomous micro rectifier was monolithically integrated in the CMas 0,35 μm technology. The tests on the μ-rectifier cou pied to the magnetic generator confirmed its functionality and high efficiency

Full textThis thesis focuses on the development of a residential cogenerator which consists of a linear induction generator driven by two Stirling engines, free-piston double-acting operating mode. The criteria characterizing such cogenerator are described and its various modes of use in the residential sector. The various technologies are reviewed.The equations of mechanics that underlie the control of the coupling of thermoelectric cogeneration and stability are defined.The electric generator is modeled to calculate the electrical coil coupled equations and the magnitudes of the equivalent circuit, this scheme allows us to reverse the pattern. The results of analytical models are validated by measurements on specially designed models. A parametric study of the structure of the generator has optimized its performances. The equations of mechanical and electrical model are used to lay the groundwork for optimization of all the cogenerator, considered as a system

Full textThis thesis is a continuation of the works based on the multi-source systems power management problems started by GREAH laboratory. It is funded by the “Haute Normandie Region”. This report presents some topologies of the DC/DC converters used in the hybrid electric vehicles applications, and the residential micro-grids ones. The studied topologies are based on the DC/DC converters such as the buck-boost and the interleaved-buck converters. Two original methods for electrical energy management in the multi-source systems are proposed and their performances are evaluated. The proposed methods enable to decouple the role of the energy source (lithium battery or fuel cell) compared to the power source (supercapacitors), and then manage the energetic exchange between the sources and the load. The proposed methods (frequency approach and distribution of the average power) consist to decompose the current of the load or the current from the pollution source into two components. The dynamic component called high frequency component is assigned to the supercapacitors, and the components which present slow variations or null called low frequency component is attributed to the lithium battery or fuel cell. For reasons of cost, the experimental test bench is carried out in the reduced scale. The obtained experimental results are used to evaluate the performance of topologies and control strategies proposed

Full textThe classical distributed energy resources (DER) supplying energy to microgrids (usually diesel generator-sets) are progressively supplanted by supplier based on renewable energy sources (RES). However, the intermittency of RES leads to major stability issues, especially in the context of microgrids, notably because these sources usually decrease the available inertia of the grid. Hence, the traditional control strategies for inverters, interfacing the various DERs connected to the microgrid, needs adapting.The virtual synchronous generator (VSG) is one of the most popular solution that can participate in increasing the microgrids inertia and that could be integrated into traditional stability studies because it presents similarities with a synchronous machine. As the VSG is still a recent concept, mostly considered for the DER integration in microgrid, various problematics remain unresolved (some of which are addressed in this manuscript). In addition, the different solutions that can be found in the literature do not consider the industrial and practical aspect of its development (also considered in this industrial thesis).This thesis is dedicated to the VSG-based inverters and their integration in microgrids with a high level of variable renewable energy penetration. This PhD have been carried out thanks to the cooperation between two laboratories, G2Elab and Gipsa-Lab, in collaboration with Schneider Electric and its R&D team, Power Conversion

Full textThe design of a micro-wind energy conversion system represents the core of this study. The attention is derived towards the brushless DC permanent magnet generator with outer rotor configuration and trapezoidal induced back-EMF voltages. The global aim of the thesis is represented by the attempt of determining the optimal geometrical and electrical design parameters of the BLDCPM generator that give the minimum total power losses in the system, over long-term wind speed cycle operation and thereby increasing the efficiency of the overall system. In advance to the optimization, an adapted simulation model needs to be developed in terms of results accuracy and simulation time. This is done in the first part of the thesis by determining the modeling level, as well as the design variables of each component of the system. As the optimization appeals to an algorithm for the design process, the reduction of the simulation time has been investigated in the third and fourth part of the thesis by developing a suitable method that allows the integration and exploitation of the available data from the wind-speed profile when determining the totality of the power losses in the system. Afterwards, the optimization methodology is presented along with the optimum results obtained, as well as comparison of several input/output parameters. Finally, experimental tests are also carried out on a reference BLDCPM machine prototype in order to verify its electronic commutation and control technique
