Pavot, Thomas. "Commande avancée d’une source d’énergie hybride pile à combustible - batterie - supercondensateur pour un drone de longue endurance". Electronic Thesis or Diss., Strasbourg, 2024. http://www.theses.fr/2024STRAD064.
Testo completoThis thesis addresses energy management strategies (EMS) for a hybrid source composed of a fuel cell (FC), a supercapacitor (SC), and a battery, intended for a long-endurance drone. The main objective is to limit the current variations requested from the FC. After analyzing the energy challenges in the aviation sector and hybridization technologies, the study explores different architectures and energy models to optimize the lifetime of the sources, particularly the FC.Three EMS strategies were examined. The first is the fixed-frequency strategy, which uses a constant cutoff frequency to separate low and high frequencies. The second, known as the adaptive strategy, varies the cutoff frequency based on the SC’s state of charge, allowing better management of current variations from the load. Finally, the H-infinity control strategy adjusts the energy distribution between the sources according to specific performance constraints.The results show that the adaptive frequency strategy significantly reduces the current variations demanded from the FC, with a reduction of up to 45 % on certain cycles, potentially extending its lifespan. On the other hand, the H-infinity control strategy proved to be less efficient and requires further optimization. Tests in both simulation and on a test bench confirm these findings, but a more detailed study on FC aging would be necessary to accurately estimate the gains in lifetime

Testo completoThis work comes within the framework of a general project dealing with the electromagnetic launch. Its main purpose is to design a pulsed power supply from a Superconducting Magnetic Energy Storage (S. M. E. S. ) able to deliver a high current pulse, during a short time, to rails of an electromagnetic launcher, identified by a resistance and an inductance. At the present day, the performances of superconducting wires lead us to retain a storage current level in the superconducting coil of about ten kA. The current pulse in the load, connected at a secondary winding not superconducting, is obtained by the fast discharge of the whole stored magnetic energy in the superconducting coil using a transformer effect. This discharge is carried out by opening the primary circuit of the transformer. The S. M. E. S. And the secondary coil have a toroidal geometry which is composed of a finite number of identical and circular elementary coils. Besides, they fit into each other in order to ensure a good magnetic coupling. The first stage of this study consists in justifying the choice of the S. M. E. S. Geometry. Two kinds of storage coil geometry are studied and compared : the solenoidal and the toroidal configuration. Several parameters are analysed such as the energy storage capacity and the stray magnetic field. The second part concerns the pulsed dischage study of the S. M. E. S. At first, the transformer without magnetic core is modelled. Afterwards, its electric and magnetic parameters are computed. The maximum current peak in the load is obtained by an impedance adaptation of the transformer secondary circuit. Its value depends on the primary and secondary time constants and the magnetic coupling coefficient of the transformer
Ramuz, Denis. "Machine généralisée alimentée par deux convertisseurs : contribution à l'étude et à la commande avec et sans capteur". Besançon, 2000. http://www.theses.fr/2000BESA2078.
Testo completoIn this thesis, the autor presents an innovative driving solution using a Double FedMachine with stator and rotor connected to two IGBT PWM converters. This is an attractive solution in high power Industrial applications requiring high dynamic performances with a large field weakening range (6 typical). This type of Drive advised for coiler-uncoiler, requires constant power in a large speed range (6 typical) and high dynamic torque response. It allows an one side to produce a torque at zero speed with the normal design of the converters and on another side to reduce the frequency of the currents and fluxes for a given speed. The tested control scheme on test bench of 3 kW uses a field oriented vector control strategy. The author propose a new control law (with mechanical sensor) with the property of simplicity to reduce the interactions beetween stator and rotor regulations. Primally , the control law without mechanical sensor is studied. The results show the high robustness of the control. Throughout the work, the simulation results (Matlab/Simulink) and the control strategies are validated by experimental results

Testo completoThis thesis deals with the design, analysis and simulation of a constant grid power wind energy conversion system based on electrical energy storage and indirectly controlled doubly fed induction generator (DFIG). This horizontal axis wind turbine system generates a constant active power through the grid under all wind conditions. The incorporation of a battery or other energy storage device in the DC link enables temporary electrical energy storage. The modelling of the mechanical part of the turbine is particularly detailed, a variable blade pitch wind turbine is used for maximal power extraction. Then, modelling, direct control and indirect control of the DFIG are presented. Independent control of active and reactive powers is achieved and the storage unit rating for this operation is particularly detailed. The Maximum Power Point Tracking (MPPT) control of this unit is also discussed. Simulation results validate the study for two experimental long duration wind speed profiles. This wind energy conversion system can offer some system service like power factor compensation or harmonic minimisation. So, the DFIG is used, with an additional control, to reduce harmonics currents present in the grid. This system facilitates the integration of the wind turbine in the distribution network because the manager of the grid can have a constant active power and some useful systems services

Testo completoTransmission of electrical power under optical form is of increasing interest. This work describes efforts to develop of simple structure of GaAs solar cells for coupling ta 814 nm laser beam. The fabrication technology developed for high efficiency solar cells can be used directly for the monochromatic applications. The cell is a p-Ga1-xA1xAs/p-GaAs/n-GaAs structure grown by liquid phase epitaxy. We describe the various parameters that we had to optimize, above all the anti-reflection layer. We report conversion efficiencies near to 50% under the 814 nm monochromatic illumination
Le, Scornec Julien. "Micro-générateurs aéroélectriques flexibles pour l’auto-alimentation de capteurs communicants". Thesis, Nantes, 2020. http://www.theses.fr/2020NANT4039.
Testo completoThe advent of the Internet of Things has rendered the ambient energy harvesting a major issue for powering communicating microsystems. In this context, this work focuses on the development of a flexible piezoelectric micro-generator able to convert the mechanical energy from low airflows. The objective is to develop autonomous microsystems, or at least to extend their lifespan with energy harvesting. To harvest ambient energy, the flexible micro-generators are made of 3 μm-thick lead zirconate titanate (PZT) thin films encapsulated between polyethylene terephthalate (PET) films. The manufacturing process of the micro-generators has been optimized in order to increase their energy efficiency. Both the optimization of the electrode structure and the geometry of the generator made the maximum harvested power increase by a factor of 625. In this work, to characterize the energy harvesting, the micro-generators were excited with different systems (shaker, traction/compression system and wind tunnel). Thus, wind tunnel tests have shown that it was possible to harvest a power of 38 μW at 10 Hz when the generator was subjected to a low airflow (6 m/s). This generator allowed to power a communicating temperature sensor during several measurement/data transmission cycles
Morel, Laurent. "Machine à double alimentation : optimisation du convertisseur et contrôle vectoriel avec et sans capteur". Besançon, 1996. http://www.theses.fr/1996BESA2066.
Testo completoA new type of variable speed drive is presented in this thesis. This new process uses a double fed machine with one rotoric converter and a particular operating mode. Actually the area speed is shared into three operating phases : firstly a reversed asynchronous mode, then a transient mode of qtator coupling on the network and a double fed mode. This proposed solution leads to an important lowering of the power electronic size with regard to a conventional solution. The oriented field control of the three modes is studied, the knowledge of the current and the voltage of both windings allows a high performance field oriented control. Moreover the reactive power on the network side can be regulated in the double fed mode operating. A predictive model is added to the control and improves the dynamic performances of the system. Lastly the control laws without mechanical sensor are studied, they allow to obtain good dynamic performances. The results show the high robustness of the control. Throughout the thesis, the simulation results and the control strategies are validated by experimental results
Ouyessaad, Hakim. "Diagnostic d'une génératrice asynchrone à double alimentation : application à l'énergie éolienne". Rouen, 2014. http://www.theses.fr/2014ROUES060.
Testo completoThe research presented in this thesis focuses on the doubly fed induction generator (DFIG) of a wind turbine diagnosis methodology implementation. Firstly, diagnosis based model methods and those without model have been investigated. In our research works, diagnosis based model and observer has been selected. Moreover, a various faults affecting the generator behavior have been presented. Then, the Takagi-Sugeno multiple models approach has been used in order to represent the generator behavior as an LPV system. The obtained T-S model by the polytopic transformation is characterized by an LPV state equation and a linear output equation. The third part of this work is dedicated to the design of an unknown input multi-observer to estimate unknown inputs and to detect the current faults of the generator sensors. Otherwise, the designed unknown input multi-observer has been used to detect the generator system faults, i. E. The faults due to both rotor and stator resistors variation witch is apparent in the change of generator temperature. Finally, H∞ formalism has been considered to design a residual generator for faults detection. Hence, a 'virtual dynamic' has been introduced in the state estimation error dynamic equation. The proposed approach has been applied to the electric network fault detection in the generator; the considered faults concern the grid voltage dip

Testo completoThis work is devoted to the study and optimization of the contactless energy and information transfer. The support used for this transfer is the magnetic induction. The aim is to feed without contact systems with up to two axes of rotation. The transfer is done through coreless transformer realized on printed circuits board (PCB). At first, we exposed a method to characterize various geometries of the air transformer. We determined the transformer parameters such as mutual inductance, parasitic capacitance, proximity effect, etc. Then, we evaluated the spatial and frequency couplings as well as the assessment of power for different transformer geometrical configuration. The transformer excitation frequency is within the range 100 kHz – 1 MHz. The last part of the manuscript deals the feasibility of a simultaneous transmission of energy and information through a system with two axes of rotation
