Electric Power Transformer Engineering


Book Description

Covering the fundamental theory of electric power transformers, this book provides the background required to understand the basic operation of electromagnetic induction as applied to transformers. The book is divided into three fundamental groupings: one stand-alone chapter is devoted to Theory and Principles, nine chapters individually treat majo




Distribution System Modeling and Analysis, Second Edition


Book Description

First introduced in 2001, Kersting’s Distribution System Modeling and Analysis is the only textbook on computational modeling for electric power distribution systems. Computer models are only as good as their input, and this intuitive work clearly explains the principles and mathematics behind these models and provides approximation methods that help students recognize when a result is not what it should be. Using the same authoritative yet accessible approach, this second edition was updated to reflect the changes and advances in the field since the first edition appeared. Nearly every chapter of this book has been updated according to new trends and areas of interest, new technologies, and the increasing spread of distributed generation. Most notably, this edition features a new chapter on the center-tapped transformer for providing three-wire service to single-phase customers. New discussions consider the effects of mutual coupling between overhead and underground lines running parallel for long distances, expand on the discussion of induction machines to consider the rotor circuit, and examine the effects of distributed generation technologies such as windmills on feeders. Illustrated with numerous figures, examples, and exercises, Distribution System Modeling and Analysis, Second Edition remains the definitive textbook for teaching students to understand and model all aspects of modern distribution systems.




Distribution System Modeling and Analysis, Third Edition


Book Description

Updated to reflect the latest changes and advances in the field, Distribution System Modeling and Analysis, Third Edition again illustrates methods that will ensure the most accurate possible results in computational modeling for electric power distribution systems. With the same simplified approach of previous editions, this book clearly explains the principles and mathematics behind system models, also discussing the "smart grid" concept and its special benefits. However, this volume adds a crucial element not found in previous editions. The first two books developed models for all components but focused less on how to actually implement those models on a computer for planning and for real-time analysis. This book includes numerous models of components and several practical examples, to demonstrate how engineers can apply and customize computer programs to help them plan and operate systems. It also covers approximation methods to help users interpret computer program feedback, so they recognize when a result is not what it should be. Another improvement is the book’s earlier introduction (in chapter 4) of the modified ladder iterative technique. The author explains the need for this method—which is used in most distribution analysis programs—detailing how it is applied and why it is among the most powerful options. Concluding with a detailed summary of presented topics that readers have come to expect, this edition provides useful problems, references, and assignments that help users apply Mathcad® and WIndmil programs to put their new learning into practice. An invaluable tool for engineering students and professionals worldwide, this book explores cutting-edge advances in modeling, simulation, and analysis of distribution systems that can ensure the continued dispersal of safe, reliable energy.

AC Circuits and Power Systems in Practice


Book Description

The essential guide that combines power system fundamentals with the practical aspects of equipment design and operation in modern power systems Written by an experienced power engineer, AC Circuits and Power Systems in Practice offers a comprehensive guide that reviews power system fundamentals and network theorems while exploring the practical aspects of equipment design and application. The author covers a wide-range of topics including basic circuit theorems, phasor diagrams, per-unit quantities and symmetrical component theory, as well as active and reactive power and their effects on network stability, voltage support and voltage collapse. Magnetic circuits, reactor and transformer design are analyzed, as is the operation of step voltage regulators. In addition, detailed introductions are provided to earthing systems in LV and MV networks, the adverse effects of harmonics on power equipment and power system protection. Finally, European and American engineering standards are presented where appropriate throughout the text, to familiarize the reader with their use and application. This book is written as a practical power engineering text for engineering students and recent graduates. It contains more than 400 illustrations and is designed to provide the reader with a broad introduction to the subject and to facilitate further study. Many of the examples included come from industry and are not normally covered in undergraduate syllabi. They are provided to assist in bridging the gap between tertiary study and industrial practice, and to assist the professional development of recent graduates. The material presented is easy to follow and includes both mathematical and visual representations using phasor diagrams. Problems included at the end of most chapters are designed to walk the reader through practical applications of the associated theory.




Distribution System Modeling and Analysis with MATLAB® and WindMil®


Book Description

This Fifth Edition includes new sections on electric vehicle loads and the impact they have on voltage drop and transformers in distribution systems. A new and improved tape-shield cable model has been developed to produce more accurate impedance modeling of underground cables. In addition, the book uses state-of-the-art software, including the power distribution simulation software Milsoft WindMil® and programming language Mathworks MATLAB®. MATLAB scripts have been developed for all examples in the text, in addition to new MATLAB-based problems at the end of the chapters. This book illustrates methods that ensure the most accurate results in computational modeling for electric power distribution systems. It clearly explains the principles and mathematics behind system models and discusses the smart grid concept and its special benefits. Including numerous models of components and several practical examples, the chapters demonstrate how engineers can apply and customize computer programs to help them plan and operate systems. The book also covers approximation methods to help users interpret computer program results and includes references and assignments that help users apply MATLAB and WindMil programs to put their new learning into practice.
