Synopsis
The latest edition of a robust treatment of the design, installation, and maintenance of GIS
In the newly revised Second Edition of Gas Insulated Substations (GIS), expert engineer Hermann Koch delivers a comprehensive exploration of all aspects of the design, installation, and lifetime management of gas-insulated equipment. The book includes the basic principles, technology, use and application, design, specification, testing, and ownership issues relevant to GIS.
The author discusses the theory of gas insulated technology, manufacturing, specification, instrument transformers, gas insulated bus, and the assembly process. The book offers a practical guide for users and equipment owners, as well as robust discussions of the different types of GIS technologies and configurations. Readers will also learn about emerging design trends and new approaches to the use of gas mixtures, alternative gases, and vacuum technologies.
The book also includes:
- A thorough introduction to definitions, standards and references in gas-insulated substations
- A comprehensive exploration of foundational information in gas-insulated substations, including the physics of gas-insulated switchgear, and its design and safety
- Practical discussions of the technology of gas-insulated substations, including their modular components, design, and development processes
- In-depth examinations of gas-insulated substation control and monitoring, including local control cabinets and digital communication
Perfect for power engineers, Gas Insulated Substations (GIS) is also an ideal resource for postgraduate students in electrical power engineering seeking the latest developments in gas-insulating switchgear and gas-insulating line technology.
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.
