Annotation of standard text IEC 60071-12-ed.1.0 :
IEC 60071-12:2022 applies guidelines on the procedures for insulation co-ordination of line commutated converter (LCC) stations for high-voltage direct current (HVDC) project, whose aim is evaluating the overvoltage stresses on the converter station equipment subjected to combined DC, AC power frequency, harmonic and impulse voltages, and determining the specified withstand voltages for equipment. This document deals only with metal-oxide surge arresters, without gaps, which are used in modern HVDC converter stations. The criteria for determining the protective levels of series and/or parallel combinations of surge arresters used to ensure optimal protection are also presented. Typical arrester protection schemes and stresses of arresters are presented. Annex A contains examples of insulation co-ordination for LCC HVDC converters which support the concepts described in the main text, and the basic analytical techniques used. LIEC 60071-12:2022 applique des lignes directrices concernant les procedures de coordination de l’isolement des stations de conversion equipees de convertisseurs commutes par le reseau (LCC) pour des installations a courant continu haute tension (CCHT), dont l’objectif est d’evaluer les contraintes de surtension exercees sur le materiel soumis a des tensions combinees de frequence, dharmoniques et dimpulsions de courant continu et alternatif et de determiner les tensions de tenue specifiees pour le materiel. Le present document traite seulement des parafoudres a oxyde metallique, sans eclateurs, qui sont utilises dans les stations de conversion a CCHT modernes. Les criteres de determination des niveaux de protection des combinaisons de montages en serie et/ou en parallele des parafoudres utilises pour assurer une protection optimale sont egalement presentes, de meme que les schemas types de la protection par parafoudre et les contraintes des parafoudres. L’Annexe A comporte des exemples de coordination de l’isolement pour les convertisseurs CCHT LCC qui prennent en charge les concepts decrits dans le corps du texte, ainsi que les techniques d’analyse de base employees.
