This text concentrates on the fundamentals of protective relaying and aims to provide lasting information in intelligible language. It covers the relative qualities of modern transmission line systems, communications channels, three-terminal applications and program design for microprocessors, and also supplies an encyclopaedic bibliography listing professional papers useful to the relay engineer.
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.
Maintaining the features that made the previous edition a bestseller, this book covers large and small utility systems as well as industrial and commercial systems. The author provides a completely new treatment of generator protection in compliance with governmental rules and regulations and supplies expanded information on symmetrical components. The text delineates individual protection practices for all equipment components; furnishes an overview of power system grounding, including system ferroresonance and safety grounding basics; analyzes power system performance during abnormal conditions; describes the relationship of input source performance to protection; and much more.
For many years, Protective Relaying: Principles and Applications has been the go-to text for gaining proficiency in the technological fundamentals of power system protection. Continuing in the bestselling tradition of the previous editions by the late J. Lewis Blackburn, the Fourth Edition retains the core concepts at the heart of power system anal
