Produktbeschreibung

A revised and updated text that explores the fundamentals of the physics of electric power handling systems

The revised and updated second edition of Electric Power Principles: Sources, Conversion, Distribution and Use offers an innovative and comprehensive approach to the fundamentals of electric power. The author - a noted expert on the topic - provides a thorough grounding in electric power systems, with an informative discussion on per-unit normalisations, symmetrical components and iterative load flow calculations. The text covers the most important topics within the power system, such as protection and DC transmission, and examines both traditional power plants and those used for extracting sustainable energy from wind and sunlight.

The text explores the principles of electromechanical energy conversion and magnetic circuits and synchronous machines - the most important generators of electric power. The book also contains information on power electronics, induction and direct current motors. This new second edition includes:
_ A new chapter on energy storage, including battery modeling and how energy storage and associated power electronics can be used to modify system dynamics
_ Information on voltage stability and bifurcation
_ The addition of Newton's Method for load flow calculations
_ Material on the grounding transformer connections added to the section on three phase transformer
_ An example of the unified power flow controller for voltage support

Written for students studying electric power systems and electrical engineering, the updated second edition of Electric Power Principles: Sources, Conversion, Distribution and Use is the classroom-tested text that offers an understanding of the basics of the physics of electric power handling systems.

Rezensionen

It is a must-read book for everyone who feels interested in area of electric power system. This book covers almost every essential item that falls in this area. By reading this book, you can expect to explore all the key components in electric power system, such as energy source, transmission line, protection mechanism, load flow, electric machine, etc. All the key concepts are discussed from fundamental physics and elaborated steps by steps. Real world examples with pictures are given in the right place to visualize the discussed items. Problem sets are included in each chapter to strengthen the learnt concepts. I am quite sure everyone from all levels can follow and understand all the contents without much difficulty.

In this second edition, a new chapter on energy storage and some other updated information are added. As a teacher and researcher in power engineering, I would say this book must be one of the best books in this area.
