This book provides a comprehensive overview of protection schemes used for power transformers and describes the internal fault conditions and external abnormalities that may disrupt the operation of a power transformer. It also highlights the issues of current protective schemes, which pose several challenges in terms of the detection of internal faults and abnormalities, including computational burden, reduced accuracy, difficulty to implement, increased cost, computational complexity, impermeability to high resistance faults (HRF), and malfunction in conditions like cross-country fault. To address these problems, the book develops an effective novel transformer protection scheme that can eliminate all the said difficulties using an innovative algorithm. Given its scope, it is a useful resource for researchers and practitioners working in the field of power system protection, allowing them to design novel protection schemes, and providing insights into the hardware validation of developed technique.

Wie ist die Wechselwirkung zwischen kritischen Infrastrukturen wie Transport, Energie und IKT? Welche Vorteile ergeben sich aus der Kopplung der genannten Systeme im Hinblick auf die Realisierung der Energiewende? Den Kern des Buches bildet die systematische Darstellung der Verbindung von Elektromobilität mit der Nutzung elektrischer Energie aus regenerativen Quellen. Durch die zunehmende Anzahl an E-Fahrzeugen entsteht eine unmittelbare Kopplung mehrerer Sektoren (Transport, Logistik, Energie, Informations- und Telekommunikation (IKT)), wodurch die Flexibilität dieser Systeme vergrößert werden kann. Diese Neuauflage ist um ein Kapitel zum autonomen Fahren erweitert worden. Besonderes Augenmerk legen die Autoren auf die didaktische Darlegung des Stoffes, um diese komplexe Problematik „so einfach wie möglich, aber nicht einfacher“ vorzustellen. Der Inhalt Elektromobilität, Kritische Infrastrukturen und Sektorenkopplung – Physikalisch-technische Beschreibung des E-Kraftfahrzeugs – Elektrische Komponenten des E-Kfz – Batteriesysteme – Brennstoffzellensysteme – Standards, Rahmenbedingungen, Normung – Elektromobilität als technisches System – Elektromobilität im Energieversorgungssystem – Geschäftsmodelle – Autonomes Fahren Die Zielgruppen Das Buch wendet sich an kommunale und städtische Entscheidungsträger, an Mitarbeiter von Energieversorgungsunternehmen und an Studierende der technischen Fächer und Ingenieure, insbesondere der Energietechnik und -wirtschaft, der Elektrotechnik, der Logistik und des Verkehrswesens. Die Autoren Prof. Dr.-Ing. Przemyslaw Komarnicki ist Sprecher des Forschungsfeldes Konvergente Versorgungsinfrastrukturen am Fraunhofer Institut IFF in Magdeburg und Professor für Elektrische Energieanlagentechnik an der Hochschule Magdeburg-Stendal. Prof. Dr.-Ing. Jens Haubrock ist Professor für Regenerative Energiesysteme und Elektrotechnik an der Fachhochschule Bielefeld. Er ist professorales Mitglied und stellvertretender Leiter des Institutes für technische Energiesysteme. Prof. Dr. Zbigniew A.
