Voltage sourced converter (VSC) valves for static synchronous compensator (STATCOM) - Electrical testing
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.
Valves de convertisseur source de tension (VSC) pour compensateur synchrone statique (STATCOM) - Essais électriques
L'IEC 62927:2017 s'applique aux valves autocommutées, conçues pour être utilisées dans un convertisseur source de tension (VSC) pour compensateur synchrone statique (STATCOM). Elle se limite aux essais de type électrique et de production.
Les essais spécifiés dans le présent document sont établis pour des valves isolées à l'air. Pour les autres types de valves, les exigences relatives aux essais et les critères d'acceptation font l'objet d'un accord entre le client et le fournisseur.
