Basic factors and general considerations in selecting the class and means of neutral grounding for a particular ac transmission or subtransmission system are covered in this guide. An apparatus to be used to achieve the desired grounding is suggested, and methods for specifying the grounding devices are given. Transformer tertiary systems, equipment-neutral grounding, and the effects of series compensation on grounding are discussed.

This book discusses key techniques of protection and fault ride-through in VSC-HVDC grids, including high-speed selective protection, DC fault current limitation, converter restarting, and DCCB reclosing strategies. It investigates how high-speed transient-variable-based protection can be used to improve grids’ acting sensitivity, acting reliability, and ability to withstand high transition resistance compared with traditional protection. In addition, it discusses the applicability of the pilot protections, including the current differential protection and travelign-wave based protection, in the dc grid, as well as the improved methods. Furthermore, it proposes several DC FCL topologies, which are suitable for DC grids. Lastly, in the context of overhead line application conditions, it explores converter restarting and DCCB reclosing strategies, which not only identify the fault property, but also limit the secondary damage to the system, improving the system’s operation security and reliability. As such, the book offers a comprehensive overview of original and advanced methods and techniques for the protection of VSC-HVDC grids.

This Green Book offers the outstanding expertise of CIGRE professionals about Flexible AC Transmission Systems (FACTS) in one concise handbook. FACTS are used to enhance AC power networks, by providing fast control of power flows and AC voltage and AC phase angles. They can be used to defer the need for additional power lines, by controlling the power flow on lines to achieve maximum utilisation of the existing lines, and/or by improving the power quality, e.g. when large disturbing loads are connected to the network. This Green Book on FACTS provides comprehensive information about the use of Power Electronics for AC system control and for Power Quality Improvement in its over 1000 pages. This book has been written by experts in the field, who come from Transmission System Operators, Network owners, manufacturers, and consultants in this field. This Green Book on FACTS covers a large range of topics in its 6 sections, as follows: AC Systems Characteristics, AC network control using conventional means and AC network control using FACTS Controllers Technical Descriptions of all current FACTS controllers, power electronic Topologies for FACTS, SVCs, STATCOM, TCSC and the UPFC and its variations Application Examples of all FACTS controllers, which include a description of controllers using saturation of iron as well as examples of all current FACTS controllers Planning and Procurement, including economic appraisals and cost benefit analysis, planning studies, environmental considerations, functional specifications Implementation of FACTS controllers, including integration and design studies, equipment design and testing and commissioning FACTS operation and lifetime management.
