Electromechanical Machinery Theory and Performance (Second Edition) (eBook)

This book is intended for an upper level undergraduate engineering course in electric power transformers and synchronous and induction machines. It includes an introduction to pulse width modulated converters, and discusses variable speed operation of ac generators and motors. Both wound fieled and permanent magnet synchronous machines are considered. Direct connect rotating machines are covered, as are machine that interface to the grid through power electronic converters. Applications to wind turbine generators are discussed. A chapter on grid connected photovoltaic systems is included.

The text present the theory of performance of these machines, and derives the commonly used equivalent circuits that are used for steady state analysis. Three phase real and reactive power flows are investigated. Machine ratings are presented and discussed, and the thermal model of a three phase liquid cooled transformer is considered.
The focus of the book is on application of transformers, ac rotating machines and photovoltaics in generating and utilizing electric power as renewable energy sources and high efficiency load applications become increasingly prominent.

The text includes practical examples, and both questions and problems with each chapter. The book includes a set of spreadsheet based problems that allow students to analyse cases that involve many repetitive calculations, such as induction motor starting.
Readers who master the material in this book will be prepared to conduct steady state power and energy analysis of these devices for design and application studies, as well as to go on to further studies in control, dynamic analysis, and advanced steady state operation.
