Improved Indirect Power Control (IDPC) of Wind Energy Conversion Systems (WECS)
Wind power capacity in the world has been increased by more than 30% over the last decade in countries which have prominent installations. Wind energy conversion systems (WECSs) based on the doubly-fed induction generator (DFIG) have dominated the wind power generation sector due to the outstanding advantages they provide, including small converter ratings (around 30% of the generator rating) and lower converter costs. Due to the non-linearity of wind power systems, the DFIG power control setup presents a big challenge especially under conditions of high variance in wind-speed and parameter sensing. To overcome these major problems, an improved IDPC (Indirect Power Control) system based on P...

Étude et Réalisation d'un Onduleur Autonome
Ce travail présente une étude de deux types d'onduleur autonome : montage en pont complet et en demi-pont. APrès une étude comparative fait entre ces deux types on a choisi la topologie en demi-pont parce qu'elle apport des avantages pour la réalisation pratique. DAns le cadre de ce travail nous avons réalisé la partie puissance et le circuit de commande rapprochée cette topologie de ce montage un petit four à induction. L'implantation de ce système est interfacée avec un Pc dont la communication entre ces derniers se fait via une carte d'acquisition de type DSP (carte dSPACE 1104) et en utilisant les environnements logiciel MATLAB/Simulink et control Desk. D'après une étude en simulation et une étude expérimentale faites sur la topologie onduleur en demi-pont, nous avons constaté qu'une bonne concordance entre les résultats de simulation et ceux expérimentaux.
Étude et réalisation d'un Onduleur à Résonance
Ce travail presente une etude de trois types d'onduleur a Resonance; serie, parallele et a injection. D'apres une etude comparative faite entre les deux premiers types(Serie et parallele), on a choisi la topologie serie parce qu'elle apporte les avantages de la simplicite et de point de vue circuit et commande. Dans le cadre de ce travail nous avons realise la partie puissance et le circuit de commande de cette topologie. L'implantation de de cette pratique est effectuee avec le systeme et interface avec un Pc, dont la communication entre le systeme et le PC se fait via une carte d'acquisition de type DSP (carte Dspace1104), et en utilisant les environnements Logiciels Matlab/Simulink et control Desk. D'apres une etude en simulation et une etude experimentale faites sur la topologie serie, nous avons constate qu'une bonne concordance entre les resultats de simulation et ceux experimentaux."
Etude et Réalisation d'un Onduleur pour Le Chauffage par Induction
Ce travail presente une etude theorique et pratique pour la realisation d'une alimentation d'un chauffage par induction. Pour aboutir a cet objectif, on a fait un rappel approfondi des phenomenes electromagnetiques, en se basant sur le modele mathematique. On a fait une simulation a base de la plate-forme MATLAB/Simulink. Dans le cadre de ce travail, on a realise la partie puissance et le circuit de commande de cette topologie. L'implantation de la partie pratique a ete effectuee avec systemes de commande, d'ou represente la carte ARDUINO (a base d'un microcontroleur), ce dernier sert a generer les signaux de commande de l'onduleur.
Doubly Fed Induction Machine
This book will be focused on the modeling and control of the DFIM based wind turbines. In the first part of the book, the mathematical description of different basic dynamic models of the DFIM will be carried out. It will be accompanied by a detailed steady-state analysis of the machine. After that, a more sophisticated model of the machine that considers grid disturbances, such as voltage dips and unbalances will be also studied. The second part of the book surveys the most relevant control strategies used for the DFIM when it operates at the wind energy generation application. The control techniques studied, range from standard solutions used by wind turbine manufacturers, to the last developments oriented to improve the behavior of high power wind turbines, as well as control and hardware based solutions to address different faulty scenarios of the grid. In addition, the standalone DFIM generation system will be also analyzed.
Modeling Power Electronics and Interfacing Energy Conversion Systems
Discusses the application of mathematical and engineering tools for modeling, simulation and control oriented for energy systems, power electronics and renewable energy This book builds on the background knowledge of electrical circuits, control of dc/dc converters and inverters, energy conversion and power electronics. The book shows readers how to apply computational methods for multi-domain simulation of energy systems and power electronics engineering problems. Each chapter has a brief introduction on the theoretical background, a description of the problems to be solved, and objectives to be achieved. Block diagrams, electrical circuits, mathematical analysis or computer code are covere...
Congenital Toxoplasmosis in Humans and Domestic Animals
Congenital Toxoplasmosis in Humans and Domestic Animals presents information about Toxoplasma gondii and its infection in neonates and different animals (cats, cattle, dogs, goats, pigs and sheep). Readers will have quick access to the pathophysiology, diagnosis, reproductive disorders (such as abortion, neonatal mortality and prematurity) and treatment of both human and veterinary toxoplasmosis. In addition, important aspects for control programs of congenital toxoplasmosis and for maternal and neonatal screening in such control programs are discussed. Thus readers will be better equipped to conduct prevention programmes and routine diagnosis of zoonotic infections related to T. gondii. This handbook is of interest to epidemiologists, doctors, veterinarians and public health specialists.
