Download or read book Numerical Differential Protection written by Gerhard Ziegler and published by John Wiley & Sons. This book was released on 2012-01-27 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: Differential protection is a fast and selective method of protection against short-circuits. It is applied in many variants for electrical machines, trans-formers, busbars, and electric lines. Initially this book covers the theory and fundamentals of analog and numerical differential protection. Current transformers are treated in detail including transient behaviour, impact on protection performance, and practical dimensioning. An extended chapter is dedicated to signal transmission for line protection, in particular, modern digital communication and GPS timing. The emphasis is then placed on the different variants of differential protection and their practical application illustrated by concrete examples. This is completed by recommendations for commissioning, testing and maintenance. Finally the design and management of modern differential protection is explained by means of the latest Siemens SIPROTEC relay series. As a textbook and standard work in one, this book covers all topics, which have to be paid attention to for planning, designing, configuring and applying differential protection systems. The book is aimed at students and engineers who wish to familiarise themselves with the subject of differential protection, as well as the experienced user entering the area of numerical differential protection. Furthermore, it serves as a reference guide for solving application problems. For the new edition all contents have been revised, extended and updated to the latest state-of-the-art of protective relaying.

Book excerpt: This comprehensive overview of 61850 standard/protocol focuses on implementation, taking the reader through the development and concepts of IEC 61850. This includes the initial work by General Motors (Manufacturing Automation Protocol), EPRI (UCA 1.0 and UCA 2.0), IEEE (TR 1550), and IEC 61850. The standard is a significant piece of many IIoT (industrial internet of things) strategies for substation communication. The book discusses and documents the basic research and theory of guaranteed multicast done for IEC 61850 GOOSE as well as the shift from variable technology to object oriented technology. The layering principles, as well as the structure, of IEC 61850 are discussed in detail as well as the actual communication profiles that have been created to support substation/distribution automation, distributed energy resources, and synchrophasors. Real applications will be discussed as well as the future direction of the standard. The author is a technical co-editor of IEC 61850 standard and a leader in US implementations, having been involved with the technology from its inception.

Download or read book Practical Methods for Analysis and Design of HV Installation Grounding Systems written by Ljubivoje M. Popovic and published by Academic Press. This book was released on 2018-02-20 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Practical Methods for Analysis and Design of HV Installation Grounding Systems gives readers a basic understanding of the modeling characteristics of the major components of a complex grounding system. One by one, the author develops and analyzes each component as a standalone element, but then puts them together, considering their mutual disposition, or so-called proximity effect. This is the first book to enable the making and analysis of the most complex grounding systems that are typical for HV substations located in urban areas that uses relatively simple mathematical operations instead of modern computers. Since the presented methods enable problem-solving for more complex issues than the ones solved using National, IEC and/or IEEE standards, this book can be considered as an appendix to these standards. - Develops general equations of lumped parameter ladder circuits - Includes the analytical expression for determination of ground fault current distribution for a fault anywhere along a cable line - Presents measurement and analytical methods for the determination of actual ground fault current distribution for high-voltage substations located in urban areas - Provides the analytical procedure for the determination of the critical ground fault position for faults appearing in outgoing transmission lines - Defines testing procedure for the correct evaluation of grounding systems of substations located in urban areas

Download or read book Citizenship and Belonging in France and North America written by Ramona Mielusel and published by Springer Nature. This book was released on 2020-01-09 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first decades of the new millennium have been marked by major political changes. Although The West has wished to revisit internal and international politics concerning migration policies, refugee status, integration, secularism, and the dismantling of communitarianism, events like the Syrian refugee crisis, the terrorist attacks in France in 2015-2016, and the economic crisis of 2008 have resurrected concepts such as national identity, integration, citizenship and re-shaping state policies in many developed countries. In France and Canada, more recent public elections have brought complex democratic political figures like Emmanuel Macron and Justin Trudeau to the public eye. Both leaders were elected based on their promising political agendas that aimed at bringing their countries into the new millennium; Trudeau promotes multiculturalism, while Macron touts the diverse nation and the inclusion of diverse ethnic communities to the national model. This edited collection aims to establish a dialogue between these two countries and across disciplines in search of such discursive illustrations and opposing discourses. Analyzing the cultural and political tensions between minority groups and the state in light of political events that question ideas of citizenship and belonging to a multicultural nation, the chapters in this volume serve as a testimonial to the multiple views on the political and public perception of multicultural practices and their national and international applicability to our current geopolitical context.
