2nd Edition
by Hermann J. Koch (Editor)
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:
