Berrahal, Khoukha, Abd El Malik Bouhentala, and Ahmed Bensalem. 2020. “Three Level Inverter Based Unified Power Flow Controller, ISSN 1755-6398”. International Journal of Power Electronics 11 (2) : 195 - 210. Publisher's Version Abstract

Unified power flow controller is a power electronics-based device utilised to improve transmission line capacity and control power flow transmitted by power transmission systems. This paper presents the application of the decoupled control strategy to control independently active and reactive power in the event of changes in the step points of the powers. Two types of controllers are used to handle the control strategy proposed: conventional PI regulator and fuzzy logic PI regulator. The fuzzy logic controller must have high performance to handle the problem of adjustment of power decoupling. Also, a three level neutral point controller inverter is used in both series and shunt parts of the UPFC to get multistep voltage wave and improve the power quality.

Le présent article traite le problème de l’échange d’énergie électrique entre des réseaux interconnectés. L’objectif principal est de développer un programme qui permet de déterminer les moments les plus économiques pour l’échange d’énergie électrique entre les réseaux électriques. Pour que ce bénéfice soit encore meilleur, l’échange doit être anticipé par une répartition optimale de la charge pour chaque réseau électrique. Pour résoudre ce problème on a conçu un modèle utilisant conjointement l’écoulement de puissances optimales et l’optimisation des bénéfices lors de l’échange de l’énergie électrique. Le modèle développé est testé sur des réseaux standards IEEE.

Rotating electrical machines play an important role in the industrial world. Among them, the three- phase squirrel cage asynchronous machines are frequently used because of their robustness, their relatively simple construction and their low cost. Nevertheless, during their lifespan, these machines are submitted to external and internal stresses which can lead to several failures. In this paper, we present the estimate of the parameters sensitive to the defects, namely the rotor currents and resistances of the rotor bars, by using the Extended Kalman filter.

In information science such as computer, telecommunications, processing of the transmission of signals or images, the components field effect plays a role. Also we are interested in our study to field-effect transistor gate Schottky micron and submicron in gallium arsenide GaAs MESFET said. In this paper, we present the results of calculating the influence of gate length on input impedance and output transistor field effect Schottky barrier gallium arsenide GaAs MESFET said, this physical model is based on the analysis of two-dimensional Poisson equation in the active region under the gate. The theoretical simulation results based on analytical expressions that we have established above, are discussed and compared with those of the experiment

In the information science and technology such as computer science, telecommunications, processing of the signals or images transmission, the field effect components plays a major role. We are interested in this study in Schottky gate gallium arsenide field-effect transistors commonly called GaAs MESFET. In this paper, we mainly present the results of calculating the influence of gate length on input and output impedances of GaAs MESFET Transistors, this physical model is based on the analysis of two-dimensional Poisson equation in the active region under the gate. The theoretical results, based on analytical expressions that we have established, are discussed and compared with those of the simulation.

Malik, Bouhentala Abd El, and Benbouza Med Salah. 2012. “Assessment of Direct Torque Control of a Double Feed Induction Machine, ISSN 2250-3021”. IOSR Journal of Engineering 2 (4) : pp.516-520. Publisher's Version Abstract
In this paper, we present the application of the control of doubly fed induction machine, using direct torque control (DTC). This method has a simple and robust control structure; the performance of DTC strongly depends on the quality of the estimated actual stator flux and torque. DTC with switching tables provide excellent torque dynamics. The implementation of the DTC applied to a double feed induction motor is validated with simulated results. The results demonstrate that the proposed controller leads to performance improvements despite its simple structure.

Dans le domaine des applications à basse vitesse, l’intérêt se porte actuellement sur l'utilisation de machines électriques directement connectées à la charge. Ceci dans l'objectif de réduire les pannes mécaniques en supprimant le multiplicateur de vitesse. La présente communication consiste à dimensionner et à étudier deux exemples de structures Vernier excitées. Dans un premier temps, nous proposons le dimensionnement, en utilisant des approches classiques, de deux machines à réluctance variable excitée soit par des aimants permanents ou encore par un circuit triphasé statorique. Dans une seconde étape, nous utilisons une approche numérique basée sur le calcul de champs magnétiques par la méthode des éléments finis pour étudier le fonctionnement des deux prototypes. Enfin, nous comparerons les performances des deux structures en fonctionnement moteur autopiloté.
