Insulation co-ordination - Part 5: Procedures for high-voltage direct current (HVDC) converter stations
Provides guidance on the procedures for insulation co-ordination of high-voltage direct current (HVDC) converter stations, without prescribing standardized insulation levels. Applies only for HVDC applications in high-voltage a.c. power systems and not for industrial conversion equipment. Principles and guidance given are for insulation co-ordination purposes only. The requirements for human safety are not covered.
Isolationskoordination - Teil 5: Verfahren für Hochspannungs-Gleichstrom-Stromrichterstationen (HGÜ-Stromrichterstationen)
Coordination de l’isolement - Partie 5: Procédures pour les stations de conversion à courant continu haute tension (CCHT)
L'IEC 60071-5:2014 donne des lignes directrices sur les procédures pour la coordination de l'isolement des stations de conversion à courant continu haute tension (CCHT), sans imposer de niveaux d'isolement normalisés. La présente norme s'applique seulement aux applications CCHT dans des systèmes de puissance alternative à haute tension et pas aux matériels de conversion industriels. Les principes et les lignes directrices donnés sont destinés aux seules fins de la coordination de l'isolement. Les exigences concernant la sécurité des personnes ne sont pas couvertes par la présente norme. La présente Norme internationale annule et remplace l'IEC TS 60071-5 parue en 2002. Suite à l'expérience technique acquise depuis la parution de la spécification technique, un consensus suffisant a émergé concernant la transformation de la Spécification technique en Norme internationale. Le contenu technique est essentiellement le même que celui de la Spécification technique avec des amendements principalement apportés pour la commodité de l'utilisateur. La structure du document a été modifiée pour permettre la division et la subdivision en des parties intégrantes complètes pour faciliter la compréhension et le référencement. Outre les révisions de haut niveau ci-dessus, les modifications techniques majeures suivantes ont été apportées par rapport à l'édition précédente: - des parafoudres ont été ajoutés à plusieurs emplacements pour refléter une certaine pratique récente du schéma CCHT (courant continu à haute tension) de 800 kV, accompagnés de leur justification, des tensions attendues, des surtensions et des contraintes relatives aux parafoudres en service; - des modifications majeures ont été apportées à l'Article 8 - tous les paragraphes relatifs aux caractéristiques, aux schémas, aux contraintes et aux spécifications des parafoudres ont été consolidés en une seule entité, l'Article 8; - les implications d'une bobine d'inductance de lissage et d'un filtre de blocage neutre placé sur une barre de neutre (comme dans certains schémas récents de 800 kV), sur la coordination des parafoudres raccordés à l'extrémité neutre ont été ajoutées; - l'utilisation possible de parafoudres sacrificiels sur la barre de neutre est introduite pour pourvoir à une énergie excessive des parafoudres dans l'éventualité plutôt peu probable d'un défaut rare particulier; - tous les paragraphes traitant d'outils d'étude et de détails de modélisation ont été consolidés à l'Article 10; - les lignes de fuite et les distances d'isolement dans l'air ont été respectivement consolidées à l'Article 11 et à l'Article 12, avec plus de détails ajoutés.
Koordinacija izolacije - 5. del: Postopki za visokonapetostne enosmerne presmerniške postaje
Standard zagotavlja smernice za postopke za koordinacijo izolacije visokonapetostnih enosmernih presmerniških postaj (HDVC), brez določanja standardiziranih izolacijskih ravni. Velja samo za uporabe HDVC v visokonapetostnih sistemih z izmenično napetostjo in ne za industrijsko pretvorno opremo. Podana načela in smernice so namenjeni samo koordinaciji izolacije. Zahteve za varnost ljudi niso obravnavane.
