Download or read book Analysis of Synchronous Machines written by T.A. Lipo and published by CRC Press. This book was released on 2017-12-19 with total page 606 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analysis of Synchronous Machines, Second Edition is a thoroughly modern treatment of an old subject. Courses generally teach about synchronous machines by introducing the steady-state per phase equivalent circuit without a clear, thorough presentation of the source of this circuit representation, which is a crucial aspect. Taking a different approach, this book provides a deeper understanding of complex electromechanical drives. Focusing on the terminal rather than on the internal characteristics of machines, the book begins with the general concept of winding functions, describing the placement of any practical winding in the slots of the machine. This representation enables readers to clearly understand the calculation of all relevant self- and mutual inductances of the machine. It also helps them to more easily conceptualize the machine in a rotating system of coordinates, at which point they can clearly understand the origin of this important representation of the machine. Provides numerical examples Addresses Park’s equations starting from winding functions Describes operation of a synchronous machine as an LCI motor drive Presents synchronous machine transient simulation, as well as voltage regulation Applying his experience from more than 30 years of teaching the subject at the University of Wisconsin, author T.A. Lipo presents the solution of the circuit both in classical form using phasor representation and also by introducing an approach that applies MathCAD®, which greatly simplifies and expands the average student’s problem-solving capability. The remainder of the text describes how to deal with various types of transients—such as constant speed transients—as well as unbalanced operation and faults and small signal modeling for transient stability and dynamic stability. Finally, the author addresses large signal modeling using MATLAB®/Simulink®, for complete solution of the non-linear equations of the salient pole synchronous machine. A valuable tool for learning, this updated edition offers thoroughly revised content, adding new detail and better-quality figures.

Download or read book Introduction to Modern Analysis of Electric Machines and Drives written by Paul C. Krause and published by John Wiley & Sons. This book was released on 2022-12-06 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction to Modern Analysis of Electric Machines and Drives Comprehensive resource introducing magnetic circuits and rotating electric machinery, including models and discussions of control techniques Introduction to Modern Analysis of Electric Machines and Drives is written for the junior or senior student in Electrical Engineering and covers the essential topic of machine analysis for those interested in power systems or drives engineering. The analysis contained in the text is based on Tesla’s rotating magnetic field and reference frame theory, which comes from Tesla’s work and is presented for the first time in an easy to understand format for the typical student. Since the stators of synchronous and induction machines are the same for analysis purposes, they are analyzed just once. Only the rotors are different and therefore analyzed separately. This approach makes it possible to cover the analysis efficiently and concisely without repeating derivations. In fact, the synchronous generator equations are obtained from the equivalent circuit, which is obtained from work in other chapters without any derivation of equations, which differentiates Introduction to Modern Analysis of Electric Machines and Drives from all other textbooks in this area. Topics explored by the two highly qualified authors in Introduction to Modern Analysis of Electric Machines and Drives include: Common analysis tools, covering steady-state phasor calculations, stationary magnetically linear systems, winding configurations, and two- and three-phase stators Analysis of the symmetrical stator, covering the change of variables in two- and three-phase transformations and more Symmetrical induction machines, covering symmetrical two-pole two-phase rotor windings, electromagnetic force and torque, and p-pole machines Direct current machines and drives, covering commutation, voltage and torque equations, permanent-magnet DC machines, and DC drives Introduction to Modern Analysis of Electric Machines and Drives is appropriate as either a first or second course in the power and drives area. Once the reader has covered the material in this book, they will have a sufficient background to start advanced study in the power systems or drives areas.

Download or read book Modeling and Stability Analysis of Inverter Based Resources written by Lingling Fan and published by CRC Press. This book was released on 2023-11-29 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Renewable energy sources interface with the ac grids via inverters and are termed inverter-based resources (IBRs). They are replacing traditional fossil fuel-based synchronous generators at a dazzling speed. In turn, unprecedented dynamic events have occurred, threatening power grid reliability. Modeling and Stability Analysis of Inverter-Based Resources provides a fundamental understanding of IBR dynamics. Developing reliability solutions requires a thorough understanding of challenges, and in this case, IBR-associated dynamics. Modeling and stability analysis play an indispensable role in revealing a mechanism of dynamics. This book covers the essential techniques of dynamic model building for IBRs, including type-3 wind farms, type-4 wind farms, and solar photovoltaics. Besides modeling, this book offers readers the techniques of stability analysis. The text includes three parts. Part 1 concentrates on tools, including electromagnetic transient simulation, analysis, and measurement-based modeling. Part 2 focuses on IBR modeling and analysis details. Part 3 highlights generalized dynamic circuit representation—a unified modeling framework for dynamic and harmonic analysis. This topic of IBR dynamic modeling and stability analysis is interesting, challenging, and intriguing. The authors have led the effort of publishing the 2020 IEEE Power and Energy Society’s TR-80 taskforce report “Wind Energy Systems Subsynchronous Oscillations: Modeling and Events,” and the two taskforce papers on investigation of real-world IBR dynamic events. In this book, the authors share with readers many insights into modeling and analysis for real-world IBR dynamic events investigation.
