Electrical Systems 1
Methods of diagnosis and prognosis play a key role in the reliability and safety of industrial systems. Failure diagnosis requires the use of suitable sensors, which provide signals that are processed to monitor features (health indicators) for defects. These features are required to distinguish between operating states, in order to inform the operator of the severity level, or even the type, of a failure. Prognosis is defined as the estimation of a systems lifespan, including how long remains and how long has passed. It also encompasses the prediction of impending failures. This is a challenge that many researchers are currently trying to address. Electrical Systems, a book in two volumes, informs readers of the theoretical solutions to this problem, and the results obtained in several laboratories in France, Spain and further afield. To this end, many researchers from the scientific community have contributed to this book to share their research results.

Fault Diagnosis, Prognosis, and Reliability for Electrical Machines and Drives
Fault Diagnosis, Prognosis, and Reliability for Electrical Machines and Drives An insightful treatment of present and emerging technologies in fault diagnosis and failure prognosis In Fault Diagnosis, Prognosis, and Reliability for Electrical Machines and Drives, a team of distinguished researchers delivers a comprehensive exploration of current and emerging approaches to fault diagnosis and failure prognosis of electrical machines and drives. The authors begin with foundational background, describing the physics of failure, the motor and drive designs and components that affect failure and signals, signal processing, and analysis. The book then moves on to describe the features of these sig...
Handbook of Asynchronous Machines with Variable Speed
This handbook deals with the asynchronous machine in its close environment. It was born from a reflection on this electromagnetic converter whose integration in industrial environments takes a wide part. Previously this type of motor operated at fixed speed, from now on it has been integrated more and more in processes at variable speed. For this reason it seemed useful, or necessary, to write a handbook on the various aspects from the motor in itself, via the control and while finishing by the diagnosis aspect. Indeed, an asynchronous motor is used nowadays in industry where variation speed and reliability are necessary. We must know permanently for the sensitive systems, the state of process and to inform the operator of the appearance of any anomaly and its severity.
Technological Innovation for Sustainability
This book constitutes the refereed proceedings of the Second IFIP WG 5.5/SOCOLNET Doctoral Conference on Computing, Electrical and Industrial Systems, DoCEIS 2011, held in Costa de Caparica, Portugal, in February 2011. The 67 revised full papers were carefully selected from numerous submissions. They cover a wide spectrum of topics ranging from collaborative enterprise networks to microelectronics. The papers are organized in topical sections on collaborative networks, service-oriented systems, computational intelligence, robotic systems, Petri nets, sensorial and perceptional systems, sensorial systems and decision, signal processing, fault-tolerant systems, control systems, energy systems, electrical machines, and electronics.
ELECTRIMACS 2022
This book collects a selection of papers presented at ELECTRIMACS 2021, the 14th international conference of the IMACS TC1 Committee, held in Nancy, France, on 16th-19th May 2022. The conference papers deal with modelling, simulation, analysis, control, power management, design optimization, identification and diagnostics in electrical power engineering. The main application fields include electric machines and electromagnetic devices, power electronics, transportation systems, smart grids, renewable energy systems, energy storage like batteries and supercapacitors, fuel cells, and wireless power transfer. The contributions included in Volume 1 will be particularly focused on electrical engineering simulation aspects and innovative applications.
Electrical Machines Diagnosis
Monitoring and diagnosis of electrical machine faults is a scientific and economic issue which is motivated by objectives for reliability and serviceability in electrical drives. This book provides a survey of the techniques used to detect the faults occurring in electrical drives: electrical, thermal and mechanical faults of the electrical machine, faults of the static converter and faults of the energy storage unit. Diagnosis of faults occurring in electrical drives is an essential part of a global monitoring system used to improve reliability and serviceability. This diagnosis is performed with a large variety of techniques: parameter estimation, state observation, Kalman filtering, spect...
Les accumulateurs électrochimiques au plomb
Que ce que soit pour les applications portables, embarquées ou stationnaires, il est indispensable de disposer de systèmes de stockage performants, aux coûts de fabrication, d'usage et de recyclage maîtrisés. Cet ouvrage étudie deux technologies de stockage électrochimique parmi les plus utilisées : les accumulateurs au plombacide et les accumulateurs au nickel. Afin de les utiliser dans des conditions optimales, il est nécessaire de maîtriser les phénomènes électrochimiques internes. Les accumulateurs électrochimiques au plomb et au nickel expose les réactions électrochimiques aux électrodes, les différentes conceptions internes, les modes de dégradation qui s'établissent en fonctionnement et les meilleures conditions d'utilisation qui permettent de préserver les performances et de prolonger les durées de vie. Didactique et accessible, il s'adresse aux métiers du génie électrique et aux industriels et électrochimistes confrontés à l'utilisation de tels systèmes.
Production d'énergie électrique à partir des sources renouvelables (Coll. Sciences et technologies de l'énergie électrique)
Les questions de développement durable et de projection des besoins futurs favorisent l'apparition de nouvelles technologies de production d'énergie et entraînent un changement de comportement des usagers. Ce livre contribue à une meilleure appréhension de ces technologies émergentes de production d'électricité. Il analyse leurs enjeux, leurs sources et leurs moyens de conversion électrique. Suivant une approche didactique et générale, cet ouvrage présente : - les systèmes de production d'électricité à partir de ressources énergétiques renouvelables des petites aux moyennes puissances (jusque 100 à 200 MW), - les notions électrotechniques de base nécessaire à la compréhension des caractéristiques de fonctionnement de ces convertisseurs, - les contraintes et problèmes d'intégration dans les réseaux électriques de ces moyens de production.
Nonstationary Systems: Theory and Applications
This book offers an overview of current and recent methods for the analysis of the nonstationary processes, focusing on cyclostationary systems that are ubiquitous in various application fields. Based on the 13th Workshop on Nonstationary Systems and Their Applications, held on February 3-5, 2020, in Grodek nad Dunajcem, Poland, the book merges theoretical contributions describing new statistical and intelligent methods for analyzing nonstationary processes, and applied works showing how the proposed methods can be implemented in practice and do perform in real-world case studies. A significant part of the book is dedicated to nonstationary systems applications, with a special emphasis on those in condition monitoring.
