Описание (английский):

IEC 62927:2017 applies to self-commutated valves, for use in voltage sourced converter (VSC) for static synchronous compensator (STATCOM). It is restricted to electrical type and production tests. The tests specified in this document are based on air insulated valves. For other types of valves, the test requirements and acceptance criteria are agreed between the purchaser and the supplier. The contents of the corrigendum of December 2017 have been included in this copy.

Overview

IEC 62927:2017 specifies electrical type and production tests for self‑commutated valves used in voltage sourced converters (VSC) for STATCOM applications. The standard is focused on electrical performance and dielectric verification of valves (based on air‑insulated designs). For non‑air insulated valve types, test requirements and acceptance criteria are to be agreed between purchaser and supplier.

Key topics and technical requirements

Scope and definitions: Terms for insulation coordination, power semiconductor behavior, converter operating states and valve structure.

General test rules: Guidance on type test performance, ambient/frequency conditions, atmospheric correction factors, handling of redundancy and permissible component failures during tests.

Operational tests: Maximum continuous operating duty, temporary overload duty, minimum start voltage, and related operational validation of the valve control and protection circuits.

Dielectric tests:

On valve supports (DC, AC, lightning impulse)
On multiple valve units (MVU) and between valve terminals (AC/DC and switching impulse methods)

Power semiconductor tests: IGBT overcurrent turn‑off testing and verification of turn‑on/turn‑off functionality.

Electromagnetic immunity: Tests for valve insensitivity to electromagnetic disturbance and acceptance criteria.

Optional tests: Short‑circuit current testing where applicable.

Production tests and inspections: Visual checks, connection/voltage‑grading checks, control/protection verification, pressure and voltage withstand checks, and functional turn‑on/turn‑off tests.

Test reporting: Requirements for presentation of type test results and evidence in lieu.

Practical applications and users

Verify electrical and dielectric performance of VSC valves intended for STATCOM units.

Define factory acceptance tests (FAT) and production test regimes for manufacturers.

Support purchaser specifications, site acceptance testing (SAT) planning, and compliance checks for utilities and independent system operators.

Provide test methods for independent test laboratories, design and QA engineers, and procurement teams to ensure valve reliability, insulation coordination, and EMC robustness.

Who uses it:

STATCOM and power‑electronics manufacturers

Utility engineers and asset owners

Test laboratories and certification bodies

System integrators and procurement specialists
