Available in PDF, EPUB and Kindle. Book excerpt: Classical synchronous motors are the most effective device to drive industrial production systems and robots with precision and rapidity. However, numerous applications require efficient controls in non-conventional situations. Firstly, this is the case with synchronous motors supplied by thyristor line-commutated inverters, or with synchronous motors with faults on one or several phases. Secondly, many drive systems use non-conventional motors such as polyphase (more than three phases) synchronous motors, synchronous motors with double excitation, permanent magnet linear synchronous motors, synchronous and switched reluctance motors, stepping motors and piezoelectric motors. This book presents efficient controls to improve the use of these non-conventional motors. Contents 1.

Download or read book Improved Indirect Power Control IDPC of Wind Energy Conversion Systems WECS written by Fayssal Amrane and published by Bentham Science Publishers. This book was released on 2019-07-26 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 PID (Proportional-Integral-Derivative) controller, has been proposed instead of the conventional power inverters. This handbook covers information about IDPC based WECS. The book starts with a general introduction to wind power system basics. Subsequent chapters provide additional knowledge about robustness tests and adaptive / intelligent control systems employed in wind energy systems. The new concept of direct and quadrature current control (Ird & Irq) under MPPT (Maximum Power Point Tracking) strategy is also explained along with novel fuzzy logic type control systems. The authors have included detailed diagrams and an appendix of WECS parameters, making this handbook a useful primer for engineering students working towards completing licenses, Masters degrees and Post-graduation programs in advanced wind power energy systems.

This book was released on 1990 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce travail est une contribution à la modélisation, à l'étude et à la commande des machines alternatives, en particulier les machines à synchrones à double alimentation dont le stator est alimenté par un réseau fixe et le rotor par un réseau variable (MADA). Notre objectif premier est la mise en œuvre des moyens et des méthodes qui facilitent le traitement analytique des équations des machines alternatives en général. Pour cela nous étudions la représentation vectorielle et l'appliquons à la modélisation de ces machines. Après avoir dans un premier temps montre l'intérêt de ces outils mathématiques pour l'étude de la commande des machines alternatives symétriques, nous les appliquons ensuite à la modélisation et à l'étude analytique du comportement de la MADA nous avons étudié tout d'abord l'alimentation rotorique de cette machine pour des sources de tensions et optimisé le fonctionnement en minimisant les pertes par effet joule. Nous avons ensuite développé l'étude de l'alimentation rotorique par des générateurs de courant. Les équations électriques sont alors plus simples et le réglage du fonctionnement est facilité. Nous avons étudié la stabilité du système pour les deux modes d'alimentation et montre la supériorité et l'intérêt de l'alimentation rotorique en courant. Parallèlement à ces études théoriques, la partie expérimentale de ces travaux est consacrée au fonctionnement à vitesse variable d'une machine asynchrone associée à un cycloconvertisseur. Nous avons adopté la commande numérique de ce convertisseur à l'alimentation rotorique de la MADA et comparé les relevés expérimentaux aux résultats théoriques

Available in PDF, EPUB and Kindle. Book excerpt: Cette étude présente des stratégies linéaires et non-linéaires de contrôle appliquées à l'asservissement en vitesse d'une Machine Asynchrone à Double Alimentation (MADA) dont les enroulements statoriques et rotoriques sont reliés à des onduleurs de tensions à Modulation de Largeur d'Impulsion indépendants. Nous avons choisi de répartir les puissances actives entre le stator et le rotor suivant un certain rapport de proportionnalité. Cela nous conduit à garantir, en régime permanent, une répartition des pulsations statoriques et rotoriques. Cette répartition est assurée dans un premier temps par deux régulateurs de pulsations réparties, et dans un deuxième temps par le biais des angles de transformation directement. Nous développons ensuite deux modèles analytiques de la MADA : le premier exprime les courants, et le second les flux. Les simulations des stratégies de contrôle linéaire (contrôle vectoriel), et non-linéaire (contrôle par mode de glissement), démontrent un bon découplage entre l'axe magnétisant et l'axe du couple. Une validation expérimentale est présentée. Les premiers résultats expérimentaux montrent le bon contrôle de l'état magnétique de la machine, ainsi que la répartition des puissances désirées à travers les pulsations.
