Full title and description

IEC TR 62757:2015/AMD1:2019 — Amendment 1: Fire prevention measures on converters for high-voltage direct current (HVDC) systems, static var compensators (SVC) and flexible AC transmission systems (FACTS) and their valve halls. This amendment provides additional guidance and updates to the original technical report, addressing fire prevention measures for converter valves and valve halls used in HVDC, SVC and FACTS installations.

Abstract

This technical report (consolidated as Edition 1.1 when combined with the 2015 first edition) gives recommendations intended primarily for utilities, consultants and project stakeholders preparing technical specifications for converter valves and valve halls. It discusses fire incidents observed in both line-commutated converter (LCC) and voltage-sourced converter (VSC) projects, and sets out general fire-prevention measures that should be adapted and specified for particular projects through agreement between purchaser and supplier.

General information

  • Status: Published / Valid (Amendment to IEC TR 62757:2015).
  • Publication date: Amendment published July 2019 (circulation date July 2019; commonly listed as 04–08 July 2019).
  • Publisher: International Electrotechnical Commission (IEC); available through national and commercial standards publishers/distributors.
  • ICS / categories: 13.220.20 — Fire protection.
  • Edition / version: Edition 1.0 (Amendment IEC TR 62757:2015/AMD1:2019); consolidated as Edition 1.1 when the 2015 report and the 2019 amendment are combined.
  • Number of pages: Amendment document: 6 pages; consolidated edition (2015 + A1:2019): 133 pages (consolidated PDF).

Scope

The report addresses fire-prevention measures specific to converter installations and valve halls associated with HVDC transmission, SVC and FACTS equipment. It covers typical fire causes and incidents observed in LCC and VSC technologies, recommended architectural and layout considerations for valve halls, fire detection and suppression options, and suggestions for purchaser–supplier contractual specification of project-specific fire safety requirements. The document is advisory (technical report / amendment) rather than a prescriptive product safety standard.

Key topics and requirements

  • Overview of fire incidents and lessons learned in HVDC, SVC and FACTS projects (LCC and VSC technologies).
  • Fire prevention measures for converter valves and associated equipment, including layout and segregation principles for valve halls.
  • Requirements and recommendations for detection, alarm and suppression systems appropriate to valve halls and converter rooms.
  • Guidance for materials, enclosure design and compartmentation to limit fire propagation and facilitate safe operations and maintenance.
  • Contractual and specification guidance for purchasers and suppliers to ensure project-specific fire-safety requirements are agreed and implemented.

Typical use and users

Primary users are utilities, system operators, consulting engineers, designers and project managers responsible for HVDC, SVC and FACTS projects; also relevant to manufacturers and suppliers of converter valves, valve-hall designers, fire-safety engineers, and regulators involved in high-voltage converter plant safety. The report is used when preparing technical specifications, conducting risk assessments, and defining fire-protection measures for new or upgraded converter installations.

Related standards

Related documents include the base IEC TR 62757:2015 technical report (the main report), and other IEC/ISO standards and national regulations addressing electrical installations, fire protection of industrial buildings, detection and suppression systems, and equipment-specific safety requirements. Project teams should review applicable national building and fire codes in addition to IEC guidance when specifying measures for valve halls and converter installations.

FAQ

Q: What is this standard?

A: It is an IEC technical report (IEC TR 62757) with Amendment 1 issued in 2019 that provides guidance on fire-prevention measures for converters and valve halls used in HVDC, SVC and FACTS systems. The amendment updates and supplements the original 2015 report.

Q: What does it cover?

A: It covers observed fire incidents, recommended prevention and mitigation measures for converter equipment and valve halls (layout, segregation, materials, detection and suppression options), and guidance for including fire-safety requirements in project specifications between purchasers and suppliers.

Q: Who typically uses it?

A: Utilities, system operators, consulting and design engineers, manufacturers and suppliers of converter equipment, fire-safety engineers, and project teams specifying or assessing HVDC/SVC/FACTS installations.

Q: Is it current or superseded?

A: The document published as Amendment 1 in July 2019 is a valid amendment to the 2015 technical report. A consolidated Edition 1.1 (2015 + A1:2019) is available; project teams should confirm they are using the consolidated Edition 1.1 or the original report plus amendment as appropriate. Verify with your national standards body or IEC webstore for the most current status.

Q: Is it part of a series?

A: Yes — it is part of the IEC TR 62757 family (the original 2015 technical report and the 2019 amendment). It was prepared by TC 22/SC 22F (power electronics for electrical transmission and distribution systems).

Q: What are the key keywords?

A: HVDC, converter, valve hall, SVC, FACTS, fire prevention, fire protection, valve, VSC, LCC, fire detection, fire suppression.
