Item Vector control of a three-level parallel structure UPS powered asynchronous machine(5th International Conference on Maintenance and Industrial Safety CIMSI’2019, 2019-12-03) Nedjem Eddine Benchouia; Bilal SOLTANI; Belgacem MADI; Mohamed SAAIDIAThis work is dedicated to the vector control of the asynchronous machine; with orientation of the rotor flow. This technique makes it possible to decouple the control of the flow from that of the torque, similar to that of the DC machine with separate excitation. Indeed, the direct flow orientation method has been developed for conventional speed control. Through the simulation results obtained, we noted a good behavior of this one for the various tests carried out, however, shortcomings were observed concerning the sensitivity to disturbances of the load torque and their rejection time. But what strongly penalizes it is essentially its low robustness vis-à-vis the variations of the moment of inertia especially compared to those of the rotor inductance. In fact, the speed response is slightly affected, and for the changes in the rotor inductance, the decoupling of the machine deteriorates.Item Fuel Cells and Hydrogen Storage: Challenges Facing Vehicle Manufacturers(3èmeCongrès International sur les Energies Renouvelables et le Développement Durable (ERDD-2019), 2019-07-31) Bilal SOLTANI; Nedjem Eddine BenchouiaThe main challenge of our time is to find renewable energy sources that meet the needs of society. Nevertheless, energy must meet several criteria such as abundance, ease and speed of use, but also the cost of production which must be low. In addition, the aspect of "clean and renewable energy" is also to be taken seriously. Today, fuel cells are a magnet for researchers because they have many advantages. First of all, these batteries have the capacity to produce a significant amount of electricity, water and heat. In addition, the reagents of the battery are the oxygen naturally present in the atmosphere and the di-hydrogen that needs to be produced. Its production is therefore a major stake for the installation of the fuel cell. Many hopes rest on the fuel cell. As we have seen, it is one of the energy sources that have the most to become and application areas. With a relatively high efficiency, zero pollutant emissions, this fuel cell has many other advantages such as the variety of batteries that can be adapted to all current needs such as transportation, global electricity generation or digital. Because of the benefits that flow from its use as an automobile fuel, hydrogen is expected to take precedence over other synthetic fuels in the not-too-distant future.Item Vehicle Embedded by a Fuel Cell System: a review(Séminaire international sur l’Industrie et la Technologie, 2021-03-13) Bilal SOLTANI; Nedjem Eddine Benchouia; Mohamed SAAIDIAAmong the various existing fuel cell, proton exchange membrane (PEM) fuel cells now seem to be the best suited to serve as a basis for the motorization of electric vehicles. This is explained in particular by their low operating temperature (about 70 ° C) and the solid nature of the electrolyte involved. In an emerging context of electromechanical system aspect involving the modeling and simulation of a set of components, the present work consists in developing a model of the system for modeling and optimization of an on-board vehicle by fuel cell system. . In this model, we will model the different parts of the system; PEMFC fuel cell, super-capacitor, converters and a permanent magnet synchronous motor. Validation by simulation is essential for its good analysis and comparison with experimental measurements. Finally, this work focuses on solving the problems of optimization to adapt it to the fuel cell system.
