Description

Now in its Third Edition, Alternative Energy Systems: Design and Analysis with Induction Generators has been renamed Modeling and Analysis with Induction Generators to convey the book’s primary objective—to present the fundamentals of and latest advances in the modeling and analysis of induction generators.

New to the Third Edition

  • Revised equations and mathematical modeling
  • Addition of solved problems as well as suggested problems at the end of each chapter
  • New modeling and simulation cases
  • Mathematical modeling of the Magnus turbine to be used with induction generators
  • Detailed comparison between the induction generators and their competitors

Modeling and Analysis with Induction Generators, Third Edition aids in understanding the process of self-excitation, numerical analysis of stand-alone and multiple induction generators, requirements for optimized laboratory experimentation, application of modern vector control, optimization of power transference, use of doubly fed induction generators, computer-based simulations, and social and economic impacts.

Reviews

"I have taught courses on renewable energy systems and induction machines, but I have never combined both of them together before. This book has shown me a new way of thinking. … The language and the examples are very accessible and intuitive. This book is ideal for a first read, an exam study, or a broad literature review."

—Luiz Fernando Lavado Villa, Laboratory for Analysis and Architecture of Systems, Toulouse, France

"To my knowledge, this is the only book devoted entirely to the induction generator, which would be sufficient reason to make it important for the international community of electrical and electronics engineers. … The text is very didactic, being suitable to be used as a textbook in engineering schools, but also appropriate for consultation and self-education. There are a large number of solved problems, and also proposed problems, which serve as additional study tools for students. [The text] makes use of modern mathematical and computational tools used in the modeling, analysis, and simulation of power generation systems with induction generators. … Following the examples of previous editions, the text is well planned, with sense of proportion between the various chapters. The main aspects of the induction generator [are covered], including constructive aspects, self-excitation, steady state analysis, transient analysis, scalar control, vector control, control-oriented modeling, simulation, and practical applications in renewable and alternative electric power generation. The text is clear and easy to follow and understand. The authors, both experienced instructors and researchers, have used all their didactic skills to approach the subjects, even those subjects usually considered complex, for the benefit of the readers, mainly graduate and undergraduate students of electrical engineering."

—Ivo Barbi, Federal University of Santa Catarina, Florianópolis, Brazil

"The text is easy to read and the figures are clear and comprehensive. The explanations are easy to follow and complete. The references to previous works are numerous and wide."

—Bertrand Raison, G2ELab, University of Grenoble, France
