| transient phenomena in electric circuits: Transient Analysis of Electric Power Circuits Handbook Arieh L. Shenkman, 2006-01-16 Every now and then, a good book comes along and quite rightfully makes itself a distinguished place amongthe existing books of the electric power engineering literature. This book by Professor Arieh Shenkman is one of them. Today, there are many excellent textbooks dealing with topics in power systems. Some of them are considered to be classics. However, many of them do not particularly address, nor concentrate on, topics dealing with transient analysis of electrical power systems. Many of the fundamental facts concerning the transient behavior of electric circuits were well explored by Steinmetz and other early pioneers of electrical power engineering. Among others, Electrical Transients in Power Systems by Allan Greenwood is worth mentioning. Even though basic knowledge of tr- sients may not have advanced in recent years at the same rate as before, there has been a tremendous proliferation in the techniques used to study transients. Theapplicationofcomputerstothestudyoftransientphenomenahasincreased both the knowledge as well as the accuracy of calculations. Furthermore, the importance of transients in power systems is receiving more and more attention in recent years as a result of various blackouts, brownouts, and recent collapses of some large power systems in the United States, and other parts of the world. As electric power consumption grows exponentially due to increasing population, modernization, and industrialization of the so-called third world, this topic will be even more important in the future than it is at the present time. |

| transient phenomena in electric circuits: Introduction to Transients in Electrical Circuits José Carlos Goulart de Siqueira, Benedito Donizeti Bonatto, 2021-08-13 This book integrates analytical and digital solutions through Alternative Transients Program (ATP) software, recognized for its use all over the world in academia and in the electric power industry, utilizing a didactic approach appropriate for graduate students and industry professionals alike. This book presents an approach to solving singular-function differential equations representing the transient and steady-state dynamics of a circuit in a structured manner, and without the need for physical reasoning to set initial conditions to zero plus (0+). It also provides, for each problem presented, the exact analytical solution as well as the corresponding digital solution through a computer program based on the Electromagnetics Transients Program (EMTP). Of interest to undergraduate and graduate students, as well as industry practitioners, this book fills the gap between classic works in the field of electrical circuits and more advanced works in the field of transients in electrical power systems, facilitating a full understanding of digital and analytical modeling and solution of transients in basic circuits. |
| transient phenomena in electric circuits: Electromagnetic Transients in Power Cables Filipe Faria da Silva, Claus Leth Bak, 2013-07-16 From the more basic concepts to the most advanced ones where long and laborious simulation models are required, Electromagnetic Transients in Power Cables provides a thorough insight into the study of electromagnetic transients and underground power cables. Explanations and demonstrations of different electromagnetic transient phenomena are provided, from simple lumped-parameter circuits to complex cable-based high voltage networks, as well as instructions on how to model the cables. Supported throughout by illustrations, circuit diagrams and simulation results, each chapter contains exercises, solutions and examples in order to develop a practical understanding of the topics. Harmonic analysis of cable-based networks and instructions on how to accurately model a cable-based network are also covered, including several “tricks” and workarounds to help less experienced engineers perform simulations and analyses more efficiently. Electromagnetic Transients in Power Cables is an invaluable resource for students and engineers new to the field, but also as a point of reference for more experienced industry professionals. |
| transient phenomena in electric circuits: Transients for Electrical Engineers Paul J. Nahin, 2018-07-05 This book offers a concise introduction to the analysis of electrical transients aimed at students who have completed introductory circuits and freshman calculus courses. While it is written under the assumption that these students are encountering transient electrical circuits for the first time, the mathematical and physical theory is not ‘watered-down.’ That is, the analysis of both lumped and continuous (transmission line) parameter circuits is performed with the use of differential equations (both ordinary and partial) in the time domain, and the Laplace transform. The transform is fully developed in the book for readers who are not assumed to have seen it before. The use of singular time functions (unit step and impulse) is addressed and illustrated through detailed examples. The appearance of paradoxical circuit situations, often ignored in many textbooks (because they are, perhaps, considered ‘difficult’ to explain) is fully embraced as an opportunity to challenge students. In addition, historical commentary is included throughout the book, to combat the misconception that the material in engineering textbooks was found engraved on Biblical stones, rather than painstakingly discovered by people of genius who often went down many wrong paths before finding the right one. MATLAB® is used throughout the book, with simple codes to quickly and easily generate transient response curves. |

| transient phenomena in electric circuits: Transient Analysis of Power Systems Dr. Juan A. Martinez-Velasco, 2014-11-26 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. |

| transient phenomena in electric circuits: High Performance Scientific And Engineering Computing Michael Breuer, Franz Durst, Christoph Zenger, 2012-12-06 In Douglas Adams' book 'Hitchhiker's Guide to the Galaxy', hyper-intelligent beings reached a point in their existence where they wanted to understand the purpose of their own existence and the universe. They built a supercomputer, called Deep Thought, and upon completion, they asked it for the answer to the ultimate question of life, the universe and everything else. The computer worked for several millennia on the answers to all these questions. When the day arrived for hyper-intelligent beings the to receive the answer, they were stunned, shocked and disappointed to hear that the answer was simply 42. The still open questions to scientists and engineers are typically much sim pler and consequently the answers are more reasonable. Furthermore, because human beings are too impatient and not ready to wait for such a long pe riod, high-performance computing techniques have been developed, leading to much faster answers. Based on these developments in the last two decades, scientific and engineering computing has evolved to a key technology which plays an important role in determining, or at least shaping, future research and development activities in many branches of industry. Development work has been going on all over the world resulting in numerical methods that are now available for simulations that were not foreseeable some years ago. However, these days the availability of supercomputers with Teraflop perfor mance supports extensive computations with technical relevance. A new age of engineering has started. |

| transient phenomena in electric circuits: Transient Stability of Power Systems Mania Pavella, Damien Ernst, Daniel Ruiz-Vega, 2012-12-06 The market liberalization is expected to affect drastically the operation of power systems, which under economical pressure and increasing amount of transactions are being operated much closer to their limits than previously. These changes put the system operators faced with rather different and much more problematic scenarios than in the past. They have now to calculate available transfer capabilities and manage congestion problems in a near on line environment, while operating the transmission system under extremely stressed conditions. This requires highly reliable and efficient software aids, which today are non-existent, or not yet in use. One of the most problematic issues, very much needed but not yet en countered today, is on-line dynamic security assessment and control, enabling the power system to withstand unexpected contingencies without experienc ing voltage or transient instabilities. This monograph is devoted to a unified approach to transient stability assessment and control, called SIngle Machine Equivalent (S1ME). |

| transient phenomena in electric circuits: Electrical Transients in Power Systems Allan Greenwood, 1991-04-18 The principles of the First Edition--to teach students and engineers the fundamentals of electrical transients and equip them with the skills to recognize and solve transient problems in power networks and components--also guide this Second Edition. While the text continues to stress the physical aspects of the phenomena involved in these problems, it also broadens and updates the computational treatment of transients. Necessarily, two new chapters address the subject of modeling and models for most types of equipment are discussed. The adequacy of the models, their validation and the relationship between model and the physical entity it represents are also examined. There are now chapters devoted entirely to isolation coordination and protection, reflecting the revolution that metal oxide surge arresters have caused in the power industry. Features additional and more complete illustrative material--figures, diagrams and worked examples. An entirely new chapter of case studies demonstrates modeling and computational techniques as they have been applied by engineers to specific problems. |

| transient phenomena in electric circuits: Transient Phenomena in Electrical Power Systems N. D. Anisimova, V. A. Venikov, V. V. Ezhkov, 2014-06-20 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. |
| transient phenomena in electric circuits: Dynamics of Saturated Electric Machines Vlado Ostovic, 2012-12-06 This book is a result of the author's work which was initiated about a decade ago and which, in the meantime, has resulted in his Ph.D. Thesis and several technical papers. The book deals with accurate modeling of electric machines during transient and steady states, a topic which has been usually avoided in the literature. The modeling techniques herein take into account all machine peculiarities, such as the type and connection of its windings, slotting, and saturation in the iron core. A special emphasis in the book is given to the exact physical interpretation of all phenomena which influence the machine's transient behavior. Besides the Introduction, the book has five chapters. The second chapter describes basic concepts of the magnetic equivalent circuit theory and has examples of magnetic equivalent circuits of several types of machines with their node potential equations. In the third chapter the transform matrices w' and w of A.C. wind ings are derived. These matrices playa very important role in the magnetic equivalent circuit theory because they connect the quantities from the ma chine's magnetic equivalent circuit, branch fluxes, and mmfs with the ma chine's phase currents and fluxes. |

| transient phenomena in electric circuits: Plasma and Spot Phenomena in Electrical Arcs Isak Beilis, 2020-09-05 This book is devoted to a thorough investigation of the physics and applications of the vacuum arc – a highly-ionized metallic plasma source used in a number of applications – with emphasis on cathode spot phenomena and plasma formation. The goal is to understand the origins and behavior of the various complex and sometimes mysterious phenomena involved in arc formation, such as cathode spots, electrode vaporization, and near-electrode plasma formation. The book takes the reader from a model of dense cathode plasma based on charge-exchange ion-atom collisions through a kinetic approach to cathode vaporization and on to metal thermophysical properties of cathodes. This picture is further enhanced by an in-depth study of cathode jets and plasma acceleration, the effects of magnetic fields on cathode spot behavior, and electrical characteristics of arcs and cathode spot dynamics. The book also describes applications to space propulsion, thin film deposition, laser plasma generation, and magnetohydrodynamics, making this comprehensive and up-to-date volume a valuable resource for researchers in academia and industry. |

Despite this, university courses treat electromagnetism and circuit theory as two separate subjects and at advanced level, students can lack a basic understanding of the classical electromagnetism applied in the context of electric circuits to fully appreciate and apply circuit theory and understand its limitations. Here the authors build on their graduate teaching experiences and lectures to treat these topics as a single subject and derive and present the important results from circuit analyses, such as Kirchhoff's laws and Ohm's law, using the ideas of the classical electromagnetism.--Prové de l'editor. |

| transient phenomena in electric circuits: Steinmetz: Engineer and Socialist Ronald R. Kline, 2019-12-12 When Charles Proteus Steinmetz (1865-1923) died suddenly at the height of his fame, his face was as familiar to Americans as that of Babe Ruth, Henry Ford, or Jack Dempsey. Newspapers quoted his views on religion, politics (he was a Socialist), science, and future technological wonders. All were intrigued by the Horatio Alger tale of the penniless, hunchbacked German immigrant who rose to fame as the Wizard of Science, chief engineer at General Electric, and symbol of the new breed of scientists who daily surpassed the feats of Thomas Alva Edison. This intellectual biography follows Steinmetz from his education in Germany to his rise as General Electric’s chief consulting engineer. Steinmetz obtained nearly 200 patents; he made his most important contributions in electrical energy loss (or hysteresis), the understanding and wider use of alternating current, and high-voltage power transmission. General Electric became Steinmetz’s home, his identity, and a platform from which he stepped onto the wider stage of world affairs. As leader of the American Institute of Electrical Engineers, Socialist councilman in Schenectady, New York, and part-time professor at Union College, Steinmetz attempted to “engineer” society in the direction of a technocratic utopia by promoting welfare capitalism, Lenin’s electrification of the Soviet Union, and other schemes — all with limited success. In a life filled with contrasts, perhaps even Steinmetz himself, a prominent Socialist serving as chief engineer of a major corporation, was not always able to separate the myth from the man. Steinmetz: Engineer and Socialist was the subject of the 2014 PBS documentary film, “Divine Discontent.” “Well informed by recent studies of similar mythologizing, Kline explains both the rise and decline of Steinmetz’s popular reputation.” — Robert Friedel, Science “Kline’s explanations are lucid and he offers broader insights about science and technology that will interest all cultural historians.” — Mark Pittenger, Journal of American History “Steinmetz not only provides the first comprehensive, technically sophisticated analysis of Steinmetz’s engineering achievements, but also carefully examines his influential political and social writings, and judiciously dissects the making of the ‘Wizard of Schenectady’ legend.” — David Sicilia, Reviews in American History |
