Anotation

IEC 61954:2021 defines type, production and optional tests on thyristor valves used in thyristor controlled reactors (TCR), thyristor switched reactors (TSR) and thyristor switched capacitors (TSC) forming part of static VAR compensators (SVC) for power system applications. The requirements of the document apply both to single valve units (one phase) and to multiple valve units (several phases). Clauses 4 to 7 detail the type tests, i.e. tests which are carried out to verify that the valve design meets the requirements specified. Clause 8 covers the production tests, i.e. tests which are carried out to verify proper manufacturing. Clauses 9 and 10 detail optional tests, i.e. tests additional to the type and production tests. This edition includes the following significant technical changes with respect to the previous edition: important clarifications were made in 4.4.1.2, 5.1.2.2, 5.1.3.2, 5.2.3.2, 6.1.2.2, 6.1.2.4, 6.1.3.2, 6.2.2.2, 6.2.2.4, 6.3.2.2 and 9.3.2. The contents of the corrigendum of June 2024 have been included in this copy. LIEC 61954:2021 definit les essais de type, les essais de production et les essais facultatifs des valves a thyristors utilisees dans les bobines dinductance commandees par thyristors (TCR - thyristor controlled reactor), les bobines dinductance commutees par thyristors (TSR - thyristor switched reactor) et les condensateurs commutes par thyristors (TSC - thyristor switched capacitor) qui font partie des compensateurs statiques de puissance reactive (SVC - static VAR compensator) pour des applications de systeme de puissance. Les exigences du present document sappliquent tant aux unites a valve unique (monophasees) quaux unites a valves multiples (polyphasees). Les Articles 4 a 7 decrivent les essais de type, c’est-a-dire les essais effectues pour assurer que la conception des valves satisfait aux exigences specifiees. L’Article 8 traite des essais de production, cest-a-dire les essais effectues pour assurer que la fabrication est correcte. Les Articles 9 et 10 decrivent des essais facultatifs, c’est-a-dire des essais supplementaires aux essais de type et de production. Cette edition inclut les modifications techniques majeures suivantes par rapport a l’edition precedente: d’importantes clarifications ont ete apportees en 4.4.1.2, 5.1.2.2, 5.1.3.2, 5.2.3.2, 6.1.2.2, 6.1.2.4, 6.1.3.2, 6.2.2.2, 6.2.2.4, 6.3.2.2 et 9.3.2. Le contenu du corrigendum de juin 2024 a ete pris en consideration dans cet exemplaire.
