Download or read book Electrical Power System Protection written by C. Christopoulos and published by Springer Science & Business Media. This book was released on 2013-04-18 with total page 620 pages. Available in PDF, EPUB and Kindle. Book excerpt: The death of Professor Arthur Wright in the summer of 1996 deprived me of a friend and a colleague whose judgement and experience shaped this book. I pay tribute to his contributions to protection and electrical engineering education. In the five years since the first edition appeared, many developments have taken place and it is now necessary to update the book. The use of digital communications and advanced signal processing techniques is now widespread and several fully numeric relays are available from manu facturers. Two new Chapters 13 and 14 have been added to introduce readers to these concepts and associated techniques. Artificial intelligence is making its impact in all engineering applications and power system protection is no exception. Expert systems, fuzzy logic, artificial neural networks, adaptive and integrated protection, synchronized measurements using the global positioning system, genetic algorithms, flexible a.c. transmission systems, are some of the techniques considered in connection with protection. Although many of these techniques have not yet found major application in protection, it is nevertheless essential for the educated protection engineer to have a basic understanding of the underlying principles and methodology so that he, or she, can evaluate their suitability for new relaying problems and applications. Chapter 15 was therefore added to guide readers through this developing area. I have also added some new material in other chapters to reflect changes over the past years.

Download or read book Transient Analysis of Power Systems written by Juan A. Martinez-Velasco and published by John Wiley & Sons. This book was released on 2015-01-27 with total page 661 pages. Available in PDF, EPUB and Kindle. Book excerpt: The simulation of electromagnetic transients is a mature field that plays an important role in the design of modern power systems. Since the first steps in this field to date, a significant effort has been dedicated to the development of new techniques and more powerful software tools. Sophisticated models, complex solution techniques and powerful simulation tools have been developed to perform studies that are of supreme importance in the design of modern power systems. The first developments of transients tools were mostly aimed at calculating over-voltages. Presently, these tools are applied to a myriad of studies (e.g. FACTS and Custom Power applications, protective relay performance, simulation of smart grids) for which detailed models and fast solution methods can be of paramount importance. This book provides a basic understanding of the main aspects to be considered when performing electromagnetic transients studies, detailing the main applications of present electromagnetic transients (EMT) tools, and discusses new developments for enhanced simulation capability. Key features: Provides up-to-date information on solution techniques and software capabilities for simulation of electromagnetic transients. Covers key aspects that can expand the capabilities of a transient software tool (e.g. interfacing techniques) or speed up transients simulation (e.g. dynamic model averaging). Applies EMT-type tools to a wide spectrum of studies that range from fast electromagnetic transients to slow electromechanical transients, including power electronic applications, distributed energy resources and protection systems. Illustrates the application of EMT tools to the analysis and simulation of smart grids.

Available in PDF, EPUB and Kindle. Book excerpt: If you are looking for a complete study of the fundamental concepts in magnetic theory, read this book. No other textbook covers magnetic components of inductors and transformers for high-frequency applications in detail. This unique text examines design techniques of the major types of inductors and transformers used for a wide variety of high-frequency applications including switching-mode power supplies (SMPS) and resonant circuits. It describes skin effect and proximity effect in detail to provide you with a sound understanding of high-frequency phenomena. As well as this, you will discover thorough coverage on: integrated inductors and the self-capacitance of inductors and transformers, with expressions for self-capacitances in magnetic components; criteria for selecting the core material, as well as core shape and size, and an evaluation of soft ferromagnetic materials used for magnetic cores; winding resistance at high frequencies; expressions for winding and core power losses when non-sinusoidal inductor or transformer current waveforms contain harmonics. Case studies, practical design examples and procedures (using the area product method and the geometry coefficient method) are expertly combined with concept-orientated explanations and student-friendly analysis. Supplied at the end of each chapter are summaries of the key concepts, review questions, and problems, the answers to which are available in a separate solutions manual. Such features make this a fantastic textbook for graduates, senior level undergraduates and professors in the area of power electronics in addition to electrical and computer engineering. This is also an inimitable reference guide for design engineers of power electronics circuits, high-frequency transformers and inductors in areas such as (SMPS) and RF power amplifiers and circuits.

Download or read book Transient Performance of Capacitive Voltage Transformers written by Tiruvaipati Srinivas Sirish and published by LAP Lambert Academic Publishing. This book was released on 2015-06-18 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: The transient response of the voltage on the secondary is investigated with following changes in the model. Two instants of switching are considered. Instrument transformers are the integral components of power systems .Capacitive Voltage Transformers (CVTs) are widely used for protection, metering and control applications. The work presents the modeling of CVT by its equivalent circuit. A 420kV CVT is considered with a line to ground fault on the primary side. Another kind of transient response called ferro resonance is also studied. Three types of ferro resonance suppression circuits (FSCs) are considered to dampen the behavior due to ferro resonance The parameters of these FSCs are discussed. The impedance, power characteristics of these FSCs with variation of frequency are studied. Furthermore, using metal oxide varistors are used to improve the performance of the FSCs.The two switching instants in presence of FSC are also evaluated .The effect of FSCs on the transient response of CVTs are presented in this work. The effect of magnetizing current of intermediate voltage transformer on the transient response is also simulated.
