This book was released on 1998 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'ANALYSE DE LA SECURITE DYNAMIQUE EN TEMPS REEL EST TRES DIFFICILE A REALISER EN RAISON DU NOMBRE IMPORTANT DE CALCULS A REALISER EN QUELQUES MINUTES SEULEMENT. JUSQU'A AUJOURD'HUI, AUCUNE METHODE NE S'EST REVELEE SUFFISAMMENT EFFICACE POUR REMPLIR CETTE TACHE. DANS CE CONTEXTE, LE FILTRAGE DES CONTINGENCES REPRESENTE UN ENJEU MAJEUR PUISQU'IL PERMET D'ECONOMISER BEAUCOUP DE TEMPS DE CALCULS. LE BUT DE NOS TRAVAUX DE RECHERCHE A ETE DE METTRE AU POINT UNE STRATEGIE DE FILTRAGE BASEE SUR LES METHODES D'ANALYSE DE LA STABILITE TRANSITOIRE EXISTANTES. DANS UN PREMIER TEMPS, LES PRINCIPALES METHODES D'ANALYSE DE LA STABILITE TRANSITOIRE ONT ETE ETUDIEES ET TESTEES A L'AIDE DE QUATRE RESEAUX ELECTRIQUES DE TAILLES DIFFERENTES. LES METHODES QUI SONT APPARUES COMME LES PLUS EFFICACES ONT ENSUITE ETE DEVELOPPEES ET MODIFIEES, AFIN D'AMELIORER LEUR RAPIDITE, LEUR FIABILITE ET LEUR PRECISION. DEUX NOUVELLES METHODES ONT AINSI ETE CREES. LA PREMIERE METHODE PERMET DE DETERMINER TRES RAPIDEMENT ET DE MANIERE TRES FIABLE LA STABILITE DU RESEAU. LA DEUXIEME PERMET DE CALCULER PRECISEMENT LE TEMPS D'ELIMINATION CRITIQUE AVEC UN MINIMUM DE SIMULATIONS. A PARTIR DE CES DEUX METHODES QUI ONT DES CARACTERISTIQUES COMPLEMENTAIRES, UNE STRATEGIE DE FILTRAGE MULTI-NIVEAU, REALISANT UN BON COMPROMIS ENTRE LA RAPIDITE, LA FIABILITE ET LA PRECISION, A ETE PROPOSEE.

Available in PDF, EPUB and Kindle. Book excerpt: Protection des réseaux électriques est destiné aux ingénieurs, aux techniciens de bureau d'études et aux exploitants travaillant dans le domaine de l'électricité. Il contient les informations théoriques et pratiques permettant de concevoir et de régler les systèmes de protection d'un réseau électrique. Il comporte sept parties : - les régimes du neutre, - l'étude des courts-circuits (maximaux, minimaux, à la terre, régimes transitoires), - les transformateurs de courant et de tension, - les fonctions de protection et leurs applications (maximum de courant phase, terre, directionnel, différentiel, image thermique, retour de puissance active et réactive), - les disjoncteurs et les fusibles, - la sélectivité (ampèremétrique, chronométrique, logique, entre fusible et disjoncteur), - la protection des transformateurs, des moteurs, des alternateurs, des jeux de barres, des condensateurs, des réseaux en boucles et des réseaux à deux arrivées. Les explications pratiques sur le fonctionnement des protections et les tableaux récapitulatifs de réglage rendent cet ouvrage accessible à tout lecteur quel que soit son niveau de connaissance, et en font un outil de travail quotidien.

Download or read book The European Landscape Convention written by Michael Jones and published by Springer Science & Business Media. This book was released on 2011-02-09 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: This important and insightful book provides, for the first time, a broad presentation of ongoing research into public participation in landscape conservation, management and planning, following the 2000 European Landscape Convention which came into force in 2004. The book examines both the theory of participation and what lessons can be learnt from specific European examples. It explores in what manner and to what extent the provisions for participation in the European Landscape Convention have been followed up and implemented. It also presents and compares different experiences of participation in selected countries from northern, southern, eastern and western Europe, and provides a critical examination of public participation in practice. However, while the book’s focus is necessarily on Europe, many of the conclusions drawn are of global relevance. The book provides a valuable reference for researchers and advanced students in landscape policies and management, as well as for professionals and others interested in land-use planning and environmental management.

Download or read book An Introduction to the African Convention on the Conservation of Nature and Natural Resources written by World Conservation Union and published by IUCN. This book was released on 2009 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: The African Convention on the conservation of nature and natural resources was adopted in 1968 in Algiers. Considered the most forward looking regional agreement of the time, it influenced significantly the development of environmental law in Africa. Two and a half decades of intense developments in international environmental law made it necessary to revise this treaty, update its provisions and enlarge its scope. This was undertaken under the auspices of the African Union (previously OAU), and the revision was adopted by its Heads of State and Government in July 2003 in Maputo. The introduction provides an overview of this new international treaty, as well as a commentary to each of its provisions.
Download or read book Applied Mathematics for Restructured Electric Power Systems written by Joe H. Chow and published by Springer Science & Business Media. This book was released on 2006-06-03 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: Applied Mathematics for Restructured Electric Power Systems: Optimization, Control, and Computational Intelligence consists of chapters based on work presented at a National Science Foundation workshop organized in November 2003. The theme of the workshop was the use of applied mathematics to solve challenging power system problems. The areas included control, optimization, and computational intelligence. In addition to the introductory chapter, this book includes 12 chapters written by renowned experts in their respected fields. Each chapter follows a three-part format: (1) a description of an important power system problem or problems, (2) the current practice and/or particular research approaches, and (3) future research directions. Collectively, the technical areas discussed are voltage and oscillatory stability, power system security margins, hierarchical and decentralized control, stability monitoring, embedded optimization, neural network control with adaptive critic architecture, control tuning using genetic algorithms, and load forecasting and component prediction. This volume is intended for power systems researchers and professionals charged with solving electric and power system problems.
Download or read book Vehicle to Grid written by Lance Noel and published by Springer. This book was released on 2019-01-04 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book defines and charts the barriers and future of vehicle-to-grid technology: a technology that could dramatically reduce emissions, create revenue, and accelerate the adoption of battery electric cars. This technology connects the electric power grid and the transportation system in ways that will enable electric vehicles to store renewable energy and offer valuable services to the electricity grid and its markets. To understand the complex features of this emergent technology, the authors explore the current status and prospect of vehicle-to-grid, and detail the sociotechnical barriers that may impede its fruitful deployment. The book concludes with a policy roadmap to advise decision-makers on how to optimally implement vehicle-to-grid and capture its benefits to society while attempting to avoid the impediments discussed earlier in the book.

Download or read book Terra 2008 written by Leslie Rainer and published by Getty Publications. This book was released on 2011-06-14 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earthen architecture constitutes one of the most diverse forms of cultural heritage and one of the most challenging to preserve. It dates from all periods and is found on all continents but is particularly prevalent in Africa, where it has been a building tradition for centuries. Sites range from ancestral cities in Mali to the palaces of Abomey in Benin, from monuments and mosques in Iran and Buddhist temples on the Silk Road to Spanish missions in California. This volume's sixty-four papers address such themes as earthen architecture in Mali, the conservation of living sites, local knowledge systems and intangible aspects, seismic and other natural forces, the conservation and management of archaeological sites, research advances, and training.
