Available in PDF, EPUB and Kindle. Book excerpt: Improve Failure Detection and Optimize Protection In the ever-evolving field of protective relay technology, an engineer’s personal preference and professional judgment are as important to power system protection as the physical relays used to detect and isolate abnormal conditions. Invaluable Insights from an Experienced Expert Protective Relay Principles focuses on probable power system failure modes and the important characteristics of the protective relays used to detect these postulated failures. The book presents useful new concepts in a way that is easier to understand because they are equally relevant to older, electromechanical and solid-state relays, and newer, more versatile microprocessor-based relays. It introduces the applications, considerations, and setting philosophies used in transmission-line, distribution-line, and substation applications, covering concepts associated with general system operations and fault detection. Topics include relay load limits, cold load pickup, voltage recovery, and arc flash. The author also delves into the philosophies that engineers employ in both urban and rural areas, with a detailed consideration of setpoint function. Analysis of Key Concepts That Are Usually Just Glossed Over This versatile text is ideal for new engineers to use as a tutorial before they open the instruction manuals that accompany multi-function microprocessor-based relays. Guiding readers through the transient loading conditions that can result in relay misoperation, the author elaborates on concepts that are not generally discussed, but can be very helpful in specific applications. Readers will come away with an excellent grasp of important design considerations for working with overcurrent, over- and undervoltage, impedance, distance, and differential type relay functions, either individually or in combination. Also useful for students as a textbook, this book includes practical examples for many applications, and offers guidance for more unusual ones.

Available in PDF, EPUB and Kindle. Book excerpt: This textbook provides an excellent focus on the advanced topics of the power system protection philosophy and gives exciting analysis methods and a cover of the important applications in the power systems relaying. Each chapter opens with a historical profile or career talk, followed by an introduction that states the chapter objectives and links the chapter to the previous ones, and then the introduction for each chapter. All principles are presented in a lucid, logical, step-by-step approach. As much as possible, the authors avoid wordiness and detail overload that could hide concepts and impede understanding. In each chapter, the authors present some of the solved examples and applications using a computer program. Toward the end of each chapter, the authors discuss some application aspects of the concepts covered in the chapter using a computer program. In recognition of requirements by the Accreditation Board for Engineering and Technology (ABET) on integrating computer tools, the use of SCADA technology is encouraged in a student-friendly manner. SCADA technology using the Lucas-Nulle GmbH system is introduced and applied gradually throughout the book. Practice problems immediately follow each illustrative example. Students can follow the example step by step to solve the practice problems without flipping pages or looking at the book's end for answers. These practice problems test students' comprehension and reinforce key concepts before moving on to the next section. Power System Protection and Relaying: Computer-Aided Design Using SCADA Technology is intended as a textbook for a senior-level undergraduate student in electrical and computer engineering departments and is appropriate for graduate students, industry professionals, researchers, and academics. The book has more than ten categories and millions of power readers. It can be used in more than 400 electrical engineering departments at top universities worldwide. Based on this information, targeted lists of the engineers from specific disciplines include the following: Electrical, computer, power control, technical power system, protection, design, and distribution engineers Designed for a three–hours semester course on "power system protection and relaying," the prerequisite for a course based on this book are knowledge of standard mathematics, including calculus and complex numbers.
Download or read book Protection of Industrial Power Systems written by T. DAVIES and published by Elsevier. This book was released on 1996-12-11 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: The protection which is installed on an industrial power system is likely to be subjected to more difficult conditions than the protection on any other kind of power system. Starting with the many simple devices which are employed and covering the whole area of industrial power system protection, this book aims to help achieve a thorough understanding of the protection necessary.Vital aspects such as the modern cartridge fuse, types of relays, and the role of the current transformer are covered and the widely used inverse definite-minimum time overcurrent relay, the theory of the Merz-Price protection system and the development of the high-impedance relay system are critically examined. This new edition has come about in response to the dramatic change from the use of electro-magnetic relays to electronic and micro-processor relays which figure in practically all new installations. Therefore, although the theory and usage are the same, the application can be much improved owing to the increased range and accuracy and the added facilities provided with the modern relays. This book reflects the change and explains the technical advantages.

Download or read book Protective Relaying for Power Generation Systems written by Donald Reimert and published by CRC Press. This book was released on 2017-12-19 with total page 713 pages. Available in PDF, EPUB and Kindle. Book excerpt: Power outages have considerable social and economic impacts, and effective protection schemes are crucial to avoiding them. While most textbooks focus on the transmission and distribution aspects of protective relays, Protective Relaying for Power Generation Systems is the first to focus on protection of motors and generators from a power generation perspective. It also includes workbook constructions that allow students to perform protection-related calculations in Mathcad® and Excel®. This text provides both a general overview and in-depth discussion of each topic, making it easy to tailor the material to students' needs. It also covers topics not found in other texts on the subject, including detailed time decrement generator fault calculations and minimum excitation limit. The author clearly explains the potential for damage and damaging mechanisms related to each protection function and includes thorough derivations of complex system interactions. Such derivations underlie the various rule-of-thumb setting criteria, provide insight into why the rules-of-thumb work and when they are not appropriate, and are useful for post-incident analysis. The book's flexible approach combines theoretical discussions with example settings that offer quick how-to information. Protective Relaying for Power Generation Systems integrates fundamental knowledge with practical tools to ensure students have a thorough understanding of protection schemes and issues that arise during or after abnormal operation.
