Die Buchreihe Elektrische Energieversorgung ist auf die Behandlung von stationären und quasistationären Zuständen des Elektroenergiesystems fokussiert und soll anhand von detaillierten Beschreibungen und Darstellungen das notwendige Rüstzeug zur Verfügung stellen, um selbständig Fragestellungen aus der Planung und Führung von elektrischen Energiesystemen behandeln zu können. Der Band Betriebsmittel und ihre quasistationäre Modellierung behandelt die Herleitung und Beschreibung der Betriebsmittelmodelle und ihrer Ersatzschaltungen in den Symmetrischen Koordinaten. Im Einzelnen wird auf die aktiven Betriebsmittel Synchronmaschine, Asynchronmaschine und Ersatznetz sowie auf die passiven Übertragungselemente Leitungen, d.h. Freileitungen und Kabel, Transformatoren, Drosselspulen und Kondensatoren detailliert eingegangen. Die Ersatzschaltungen sind die Basis für die Berechnung und Analyse von eingeschwungenen stationären und quasistationären Betriebszuständen in Elektroenergiesystemen und für die Auslegung der Betriebsmittel sowie für die Analyse des grundsätzlichen Betriebsverhaltens und der elektrischen Eigenschaften in fehlerfreien als auch in gestörten Betriebszuständen. Univ.-Prof. Dr.-Ing. habil. Lutz Hofmann ist Leiter des Instituts für Elektrische Energiesysteme der Leibniz Universität Hannover und vertritt dort das Fachgebiet Elektrische Energieversorgung. Außerdem ist er Themenfeldleiter »Übertragungsnetze« am Fraunhofer-Institut für Energiewirtschaft und Energiesystemtechnik in Kassel. Volume 2 describes the operation, mathematical models, and equivalent circuits for symmetric and asymmetric operational states. On this basis, the work explains the stationary and quasi-stationary operational behavior of these states, along with the most important procedures for calculating three-phase systems. Key equations and models are collected in a concise and clearly organized table.

This book offers a collection of 30 scientific papers which address the problems associated with the use of power electronic converters in renewable energy source-based systems. Relevant problems associated with the use of power electronic converters to integrate renewable energy systems to the power grid are presented. Some of the covered topics relate to the integration of photovoltaic and wind energy generators into the rest of the system, and to the use of energy storage to mitigate power fluctuations, which are a characteristic of renewable energy systems. The book provides a good overview of the abovementioned topics.
