Synopses & Reviews
With nearly two-thirds of global electricity consumed by electric motors, it should come as no surprise that their proper control represents appreciable energy savings. The efficient use of electric drives also has far-reaching applications in such areas as factory automation (robotics), clean transportation (hybrid-electric vehicles), and renewable (wind and solar) energy resource management. Advanced Electric Drives utilizes a physics-based approach to explain the fundamental concepts of modern electric drive control and its operation under dynamic conditions. Author Ned Mohan, a decades-long leader in Electrical Energy Systems (EES) education and research, reveals how the investment of proper controls, advanced MATLAB and Simulink simulations, and careful forethought in the design of energy systems translates to significant savings in energy and dollars. Offering students a fresh alternative to standard mathematical treatments of dq-axis transformation of a-b-c phase quantities, Mohan’s unique physics-based approach “visualizes” a set of representative dq windings along an orthogonal set of axes and then relates their currents and voltages to the a-b-c phase quantities. Advanced Electric Drives is an invaluable resource to facilitate an understanding of the analysis, control, and modelling of electric machines.
Synopsis
Control of electric drives requires transforming to dq-frame from a-b-c phase-domain. Most research literature and textbooks in this field treat dq-axis transformation of a-b-c phase quantities on a purely mathematical basis, without relating this transformation to a set of windings that could be visualized. The physics-based approach adopted in this book is different and unique - the author visualizes a set of representative dq windings along an orthogonal set of axes and then relates their currents and voltages to the a-b-c phase quantities. This physics-based discussion follows seamlessly from the treatment of space vectors in the author's previous Wiley publications.
Synopsis
Electric drives in sustainable energy systems use a physics-based approach to electric drive control. The proper control of electric motors and systems represents significant energy savings and has applications in factory automation, clean transportation, and renewable energy resource management. Adopting a physics-based approach to the dq-axis transformation of a-b-c phase quantities, this book provides a comprehensive explanation of how electric drives operate under dynamic conditions. It features in-class discussion problems, a hardware and software lab with solutions manual, online homework problems, video clips and slides, and quizzes to reinforce fundamentals.
