Full title and description

Voltage sourced converter (VSC) valves for static synchronous compensator (STATCOM) - Electrical testing. This document specifies electrical type and production tests for self‑commutated VSC valves used in STATCOM applications and includes the 2023 amendment to the original 2017 publication.

Abstract

IEC 62927 (with Amendment 1, 2023) applies to self‑commutated valves intended for use in voltage sourced converters for static synchronous compensators (STATCOM). The standard is restricted to electrical type and production tests, with test procedures based primarily on air‑insulated valve designs. Where other valve constructions are used, test requirements and acceptance criteria are to be agreed between purchaser and supplier. The 2023 publication includes Amendment 1 and is also available as a consolidated (CSV) edition that incorporates the changes into the 2017 text.

Scope

The standard covers electrical type and production testing of self‑commutated VSC valves specifically for STATCOM applications. Test procedures are defined for valves with air insulation; for other insulation or valve arrangements the test program and acceptance criteria should be negotiated between purchaser and supplier. The scope excludes mechanical or factory‑assembly requirements beyond those necessary for the electrical tests specified.

Key topics and requirements

• Applicability to self‑commutated VSC valves used in STATCOM systems.
• Defined electrical type tests and production tests to verify valve performance and safety.
• Tests based on air‑insulated valve constructions; special constructions require purchaser/supplier agreement on test adaptation and acceptance criteria.
• Requirements cover electrical verification relevant to insulation, functional performance under specified conditions, and production‑level checks (as applicable).
• Amendment 1 (2023) updates and clarifies specific test procedures and acceptance provisions and is provided both as a standalone amendment and as a consolidated edition with the 2017 text.

Typical use and users

IEC 62927 is used by VSC valve manufacturers, STATCOM system integrators and original equipment manufacturers (OEMs), independent test laboratories, utility procurement and acceptance engineers, and certification bodies that perform or witness electrical type and production tests for power‑electronic valve assemblies.

Related standards

The document is produced under IEC TC 22/SC 22F (power electronics for electrical transmission and distribution systems) and is typically referenced alongside other IEC and EN standards covering power‑electronics equipment testing, high‑voltage test techniques, insulation coordination and product safety. Users should consult the IEC catalogue and TC 22/SC 22F publications for specific normative and informative cross‑references when preparing tests or procurement specifications.

FAQ

Q: What is this standard?

A: IEC 62927 (with Amendment 1, 2023) is an IEC technical standard that specifies electrical type and production tests for self‑commutated VSC valves used in STATCOM applications.

Q: What does it cover?

A: It covers electrical verification — type and production testing — of VSC valve assemblies for STATCOMs, with procedures based on air‑insulated valve constructions and guidance that non‑air designs require purchaser‑supplier agreement on adapted tests and acceptance criteria.

Q: Who typically uses it?

A: Valve and STATCOM manufacturers, system integrators, test laboratories, utilities and procurement/certification teams use the standard to define and carry out electrical tests and to set acceptance criteria for delivered valve equipment.

Q: Is it current or superseded?

A: The 2017 base standard with Amendment 1 (published 11 May 2023) is the current published text; a consolidated 2017+AMD1:2023 CSV edition is available. The IEC record indicates a stability date consistent with continued use through the late 2020s (catalogue stability date shown as 2029 for the consolidated entry).

Q: Is it part of a series?

A: It is part of the body of IEC work under TC 22/SC 22F addressing power electronics for transmission and distribution systems. It is published as a base standard (2017) with an amendment (2023) and is offered as a consolidated edition (CSV) that integrates the amendment into the main text.

Q: What are the key keywords?

A: STATCOM; VSC; self‑commutated valve; electrical testing; type tests; production tests; air‑insulated valve; IEC 62927; Amendment 2023.
