This book provides a thorough approach for mastering the behavior and operation of induction motors, an essential device in the modern industrial world. Its way of presentation renders this book suitable for selfteaching by students, engineers, and researchers in the field of electrical engineering. It covers the modern theory of induction motor applications and control methods. The transient analysis of both three-phase and single-phase induction motors as well as that of the double-cage motors are developed. The principles of such modern control methods as Fiel-Oriented Control, Direct Torque Control and Computed Charges Acceleration Method are clearly treated in this monograph. Numerous equations, simulations, and figures are presented.

Transient Phenomena in Electrical Power Systems: Problems and Illustrations deals with the technique of calculating the different transient phenomena in electrical power systems. Concrete examples are given to show the character of the transient processes, and the order of magnitude is derived in some typical cases. Topics covered include equivalent circuits, steady-state quantities, and the initial conditions of a transient process. The characteristics of generators and synchronous condensers are also considered. Comprised of nine chapters, this book begins with an introduction to the units of measurement as well as the equations of the system and its elements, such as frequency regulators, turbine governors, and transformers. The second chapter presents examples of the construction of equivalent circuits and the determination of the steady-state operation of a system, along with the original condition that precedes the transient process. The third and fourth chapters deal with different characteristics of generators, synchronous condensers, and loads of electrical systems. The fifth chapter examines the general criteria of stability used in calculations of the conditions in electrical systems. Problems of static stability and the effect of large oscillations on stability are discussed in the next three chapters. The final chapter is devoted to special problems on the variation of operating conditions, frequency variation, and the flow of power between systems. This monograph is written for design engineers, operation engineers, apprentices, and students.

This book provides an understanding of the nature of short-circuit currents, current interruption theories, circuit breaker types, calculations according to ANSI/IEEE and IEC standards, theoretical and practical basis of short-circuit current sources, and the rating structure of switching devices. The book aims to explain the nature of short-circuit currents, the symmetrical components for unsymmetrical faults, and matrix methods of solutions, which are invariably used on digital computers. It includes innovations, worked examples, case studies, and solved problems.
