An Introduction to The Digital Protection of Power Systems

The applications of digital techniques in power system protection have been established in 1969, and since then, those applications have been received accelerating interest. The growing abilities of the digital computers and hence the digital relays, make them to be more powerful and cheaper than the analog relays. The advance development in hardware engineering has been followed by a rapid protection engineering studies to create new digital protection algorithms. The main goal of these studies is to reduce the operation time, and to increase both security and selectivity of the proposed algorithms. Digital protection developments have been published in scientific and technical literatures, such as the proceedings of transactions, the proceedings of conferences, the publications of the various manufacturers, and in a limited number of books in this field. Any researcher or professional engineer, who is interesting in studying a special problem in the digital protection field, finds himself surrounded by many references that he has to dive in. Therefore, books which can be regarded as an adequate introduction to the digital power system protection, become more than necessary. This book t includes most of what a student, a researcher, or an engineer needs to go deeper in this field. The main headlines of this book are :  -STRUCTURE AND OPERATION OF THE DIGITAL PROTECTION SYSTEM.  -MATHEMATICAL PRINCIPLES FOR DIGITAL PROTECTION ALGORITHMS  -DIGITAL ALGORITHM FOR TRANSMISSION LINE PROTECTION BASED ON FUNDAMENTAL FREQUENCY COMPONENTS  -TRANSIENT ULTRA HIGH SPEED ALGORITHMS FOR TRANSMISSION LINE PROTECTION.  -DIGITAL PROTECTION OF POWER TRANSFORMER Read more
