Full textNowadays, the sophistication and the multiplication of electrical power systems, characterize technological and human society evolutions. Electrical energy from production systems is an essential factor for the development and improvement of living conditions and industrial activities. In electric power systems, as in the field of electric drives, which can be operated at variable speed, the Doubly Fed Induction machine (DFIM) occupies more and more space. This machine is particularly appreciated because it offers advantages over other types of electric machines such as reliability, robustness, and lower cost. It is this type of machine that is used in most current wind turbines.However, despite the advantages of this machine, it is not immune to failures. The most common ones are listed as follows: a) short circuit on stator and rotor windings, b) rotor bar breaks, c) bearing faults, d) eccentricity faults of the iron gap. In the case of maintenance, these types of defects must be detected in their early stages and located, because they can lead to high maintenance costs, production downtime and significant degradation.The diagnosis of such system encourages researches in laboratories, both industrial and academic, to develop effective monitoring devices. Many methods have been studied in this field, in order to be able to react as soon as possible and to avoid a harmful aggravation of defects. The aim is to ensure operation of the system, production of electrical energy and reduction of maintenance costs. These studies are still ongoing in the various research centers.This manuscript presents new methodologies to diagnose short circuit faults between turns in stator winding of a DFIM. These developed approaches are based on a model or from amplitudes of harmonic components of vibratory signal or from characteristics of geometric shape of currents according to short-circuit rates. The analized signals are vibrations (only for experimental case) and currents (theoretical and experimental cases). The presented methods use classical techniques such as the Fourier Transform (FT) and the Park Vector Approach (PVA). The FT is used to observe the spectral evolution of the harmonics and more particularly of their amplitude. Then, PVA is used to exploit characteristics of geometrical shape of currents. The DFIM is analytically modeled by multi-coupled circuit model. In this work, the proposed approaches were simulated on Matlab environment and validated on a real device using a 0.3kW wound rotor asynchronous machine (DFIM). The studied DFIM can be configurated with a short circuit rate between turns of 2.5%, 5%, 10%, 20%, 30% to 40% on one phase (phase A)
Costacèque-Cecchi, Bruno. "Stein's method for extreme value distributions." Electronic Thesis or Diss., Institut polytechnique de Paris, 2024. http://www.theses.fr/2024IPPAT045.
Full textExtreme value theory deals with the probability of occurrence of extreme events, such as floods, droughts or financial crises. An important part of that theory relies on limit theorems, such as the extreme value theorem, or the Pickands-Balkeman-de Hann theorem. In order to apply those theorems accurately and approximate efficiently the usually unknown distribution of the extreme data by its limit model, one needs to quantify the speed of convergence of those theorems. A manner of doing so is to use the generator approach of Stein's method. That is why in this thesis we construct a family of Markov semi-groups whose invariant measure is an extreme-value distribution. We do so via a Mehler's formula, which relies itself on the stability property satisfied by max-stable distributions. Thanks to this definition, the semi-groups satisfy similar properties to the Ornstein-Uhlenbeck (commutation rule, Poincaré's inequality, covariance identities, etc.). We then proceed to apply those results to the generator approach of Stein's method to deduce rates of convergence to extreme-value distributions in various settings. The last chapter focuses on Poisson processes whose intensity measure satisfies an homogeneity assumption and how their standard properties translate into new results for max-stable distributions, thus shedding a new light on the contents of the previous chapters

Full textThe growth of the Internet and the evolution of communicating devices have allow the integration of the computer world and the real world, paving the way for developing new types of applications such as pervasive and ubiquitous ones. These applications must run in heterogeneous, distributed and open environments that evolve constantly. In such environments, the availability of services and devices, the preferences and location of users may change at any time during the execution of applications. The variability of the execution context makes the execution of an application dependent on the available services and devices. Building applications capable of evolving dynamically to their execution context is a challenging task. In fact, the architecture of such an application cannot be fully known nor statically specified at design, development or deployment times. It is then needed to redefine the concept of dynamic application in order to cover the design, development, execution and management phases, and to enable thus the dynamic construction and evolution of applications. In this dissertation, we propose a model-driven approach for the design, development and execution of dynamic applications. We defined a component service model that considers dynamic properties within a component model. This model allows defining an application by its intention (its goal) through a set of composition properties, constraints and preferences. An application is thus specified in an abstract way, which allows controlling its gradual composition during development and execution times. Our approach aims to blur the boundary between development-time and runtime. Thus, the same model and the same composition mechanisms are used from design to runtime. At runtime, the composition process considers also the services available in the execution platform in order to compose applications opportunistically; and the variability of the execution context in order to adapt compositions dynamically. We implemented our approach through a prototype named COMPASS, which relies on the CADSE platform for building software design and development environments, and on the APAM platform for building an execution environment for dynamic service-based applications

Unfortunately, data is rarely available, is cost to obtain, or is not adapted to most of cases due to a lack of quality.An automated data generator is a good way to generate quickly and easily data that are valid, in different sizes, likelihood and diverse.In this thesis, we propose a novel and complete model driven approach, based on constraint programming for automated data generation
