Gas Insulated Substations - (IEEE Press) 2nd Edition by Hermann J Koch (Hardcover)

About the Book

"A unique, comprehensive book on all aspects of the design, installation and lifetime management of gas insulated equipment (referred to as GIS). This book includes basic principles, technology, use & application, design, specification, testing and ownership issues. It covers the theory of Gas Insulated Technology; manufacturing, specification, instrument transformers, Gas Insulated Bus, and the assembly process; control and monitoring; testing; and applications. This book can be used as a specialized textbook but also provides a practical guide for users and equipment owners. The book explores the different types of GIS technologies and configuration but also the emerging design trends, which includes new approaches to the use of gas mixtures, alternative gases and vacuum technologies"--

Book Synopsis

GAS INSULATED SUBSTATIONS

An essential reference guide to gas-insulated substations

The second edition of Gas Insulated Substations (GIS) is an all-inclusive reference guide to gas insulated substations (GIS) and its advanced technologies. Updated to the latest technical developments and applications, the guide covers basic physics of gas insulated systems, SF6 insulating gas and its alternatives, safety aspects and factors to choose GIS. GIS technology, its modular structure, control and monitoring systems, testing, installation rules and guidelines for operation, specification, and maintenance. Detailed information on various types for GIS, with 14 reference project explanations and three extensive case studies give information for the best solutions of practical applications. Special solutions using mobile substations concepts, mixed technology switchgear (MTS) with air and gas insulated technology, underground substations, and the use of special GIS substation buildings e.g., shopping centers, parking lots, city parks, business complexes' or subway stations are explained. Future developments of GIS technology are shown for the next steps in alternatives to SF6, low power instrument transformers, and digitalization of substations.

A new chapter explains advanced technologies applied to GIS projects which cover the following; environmental issues for the substation permission process, insulation coordination studies for the network requirements including very fast transients, project scope development, risk-based asset management, health and safety impact, electromagnetic fields, SF6 decomposition byproducts and condition assessment.

Disruptive development steps in gas insulated substations technologies are also covered in this second edition. Vacuum breaking and switching technology for rated voltages of up to 500 kV is explained in detail with its physical background. Principle function and possible implementation of low power instrument transformers (LPIT) are explained and examples of applications are given. The principles of digital twin for gas insulated substations (GIS) and gas insulated transmission lines (GIL) are explained in theory and project applications show the practical use and advantage. The wide and fast-growing technical field of offshore GIS applications for AC and DC is explained on many examples and gives information on special requirements when getting offshore. Theoretical requirements on DC gas insulated systems, methods of testing, prototype installation tests, modular design features, and advantages in applications are given. Finally, impact and advantages of digital substations using GIS are explained.

Key features:

• Written by leading GIS experts involved in development and project applications
• Discusses practical and theoretical aspects
• Detailed material of GIS for new and experienced GIS users, and project planners
• Invaluable guide to practicing electrical, mechanical and civil engineers as well as third- and fourth-year electric power engineering students
