Ces machines ont pour but de combiner ainsi les avantages des machines a aimants permanents, notamment leur tres bon rendement energetique, a ceux des machines a excitation controlable possedant la facilite de fonctionnement a vitesse variable. Le flux d'excitation dans ces machines est la somme d'un flux cree par des aimants permanents et un flux d'excitation cree par des bobines. Le controle de ce flux permet un fonctionnement plus souple a vitesse elevee, un meilleur dimensionnement de l'ensemble convertisseur-machine et une amelioration du rendement energetique.

This generator is characterized by a robust structure where no brushes or slip rings are required. Moreover, the flux is created by both permanent magnets and DC excitation coils. Thus, it may be adjusted easily, which makes the architecture suitable for a WCS. Unfortunately, the electromagnetic torque ripple is relatively important in this kind of generator. The rippling may propagate to the drive train of the wind turbine and thereby may have a detrimental effect on the WCS lifetime through mechanical vibrations. This work investigates two techniques for reducing the electromagnetic torque ripple. The approaches include the circuit topology and the control strategy. The two methods have been tested by simulation and then, a set of specifications regarding the acceptable inductances and flux harmonics' amplitude is provided.

In this work, experimental tests characterizing the SRMPV are presented. Based on these experiments, the first mathematical model of this complex system is developed and implemented under the Matlab-Simulink platform. In order to optimize the design of the SRMPV, the simulation platform is used to perform a sensitivity study. This research will focus on the determination of the optimal number of coils, the optimal air gap, and the optimal winding cross area of the switched reluctance motor.

Hybrid automobile vehicles are now produced in series (for example, Peugeot-508 RXH) and the first shunting locomotive TEM9H «Sinara Hybrid» has been produced in Russia. There are two main reasons for this evolution: the problems of energy saving and environmental protection [1]. The theory and structure of hybrid power drives have taken shape only in general terms by present time, in addition, there are a great number of alternatives for separate operation elements. For example, buffered energy storage may be represented by flywheels, batteries, super-capacitors and even by superconducting inductive energy storage (cryogenic coil) [2]. According to the elements mentioned above, the present paper presents a technical project for an experimental installation dedicated to the study of a hybrid traction drive for a land vehicle, the choice of its parameters and the synthesis of its control system.

The control aims to meet the torque and speed requirements while insuring minimal copper losses. Extended Lagrange multipliers optimization method (Kuhn-Tucker conditions) is used to elaborate analytical expressions for the optimal reference armature currents as well as for the field current if with respect to armature current and voltage constraints. Simulation over the new European driving cycle proves that the proposed optimal control leads to the lowest copper losses compared to the results obtained by any other commonly used synchronous motor control strategy.

But it is usually necessary to learn a specific "vocabulary". In this paper, a new methodology of design is proposed for the control of electrical generators, based on dynamical equivalent circuits. In this case, the only vocabulary which is required (electrical circuits) is already known by electrical engineers and researchers. This user-friendly method is applied with success to a doubly-fed induction machine used as a variable speed constant frequency (VSCF) generator. Les representations graphiques des systemes dynamiques sont nombreuses. La plus couramment utilisee est celle des schemas-blocs. Toutefois, d'autres formalismes existent tels que les bond-graph ainsi que les graphes informationnels de causalite (GIC) et les representations energetiques macroscopiques (REM), tous potentiellement multiphysique. Les schemas dynamiques phasoriels (SDP) presentes ici proposent une approche limitee au domaine electrique avec des symboles deja connus, dont l'interpretation physique est immediate. Cet outil est particulierement interessant pour la synthese de commandes de generateurs comme cela est illustre avec la machine asynchrone a double alimentation (MADA).

Blade technologies differ in material and fabrication processes, and this results in variations of the blade mass and cost. According to the blade technology, the blade mass can be characterized by an analytical function of the blade length. Results show a clear advantage of reducing the blade mass. The mass of commercial blades has been increasing as the square of their length. If future development efforts can maintain this trend, a benefit for offshore wind energy is expected.

The purpose is to highlight which model is recommended to be used during the design process of generator. Several measures on the Epstein frame have been performed with realistic flux density waveforms. These waveforms ensure a fair comparison to the application. Some useful conclusions on the iron loss models are obtained for use in the design process.
