Performance of high-voltage direct current (HVDC) systems with line-commutated converters - Part 2: Faults and switching
IEC/TR 60919-2:2008 provides guidance on the transient performance and fault protection requirements of high voltage direct current (HVDC) systems. It concerns the transient performance related to faults and switching for two-terminal HVDC systems utilizing 12-pulse converter units comprised of three-phase bridge (double way) connections but it does not cover multi-terminal HVDC transmission systems. However, certain aspects of parallel converters and parallel lines, if part of a two-terminal system, are discussed. The converters are assumed to use thyristor valves as the bridge arms, with gapless metal oxide arresters for insulation co-ordination and to have power flow capability in both directions. Diode valves are not considered in this report. This second edition cancels and replaces the first edition, published in 1991, and constitutes a technical revision. It includes the following main changes with respect to the previous edition: it concerns only line-commutated converters;isignificant changes have been made to the control system technology; some environmental constraints, for example audible noise limits, have been added; the capacitor coupled converters (CCC) and controlled series capacitor converters (CSCC) have been included.

Fonctionnement des systèmes à courant continu haute tension (CCHT) munis de convertisseurs commutés par le réseau - Partie 2: Défauts et manoeuvres
La CEI/TR 60919-2:2008 fournit des indications générales sur les performances de fonctionnement transitoire et sur les exigences de protection contre les défauts pour les systèmes à courant continu haute tension (CCHT). Il se rapporte au fonctionnement transitoire lié aux défauts et manoeuvres dans le cas des systèmes CCHT à deux extrémités, utilisant des convertisseurs à 12 impulsions comprenant des ponts de Graetz hexaphasés mais ne couvre pas les systèmes de transmission CCHT multiterminaux. Cependant, certains aspects liés à la mise en parallèle de convertisseurs et de lignes, s'ils relèvent d'un système à deux extrémités, seront également abordés. Les convertisseurs sont supposés utiliser des valves à thyristors dans les bras de pont, avec des parafoudres à oxyde métallique sans éclateur pour la coordination de l'isolement, et permettre le transport d'énergie dans les deux sens. Les valves à diode ne sont pas prises en considération dans le présent rapport. Cette deuxième édition annule et remplace la première édition, parue en 1991, et constitue une révision technique. Elle contient les changements fondamentaux suivants par rapport à l'édition précédente: elle ne concerne que les convertisseurs commutés par le réseau; des changements significatifs ont été effectués pour la technologie du système de contrôle; certaines limites environnementales ont été introduites, par exemple les niveaux de bruit audible maximaux; les convertisseurs connectés au travers de condensateurs (CCC) et les convertisseurs à condensateurs en série contrôles (CCSC) ont été ajoutés.
Lastnosti visokonapetostnih enosmernih (HVDC) sistemov z vodovno komutiranimi pretvorniki - 2. del: Okvare in stikanje (IEC/TR 60919-2:2008)
Ta del IEC 60919, ki je tehnično poročilo, podaja vodilo o zahtevah glede prehodnih lastnostih in varovanjem pred okvarami za visokonapetostne enosmerne (HVDC) sisteme. Zadeva prehodne lastnosti, povezane z okvarami in stikanjem za dvoterminalske HVDC sisteme, ki uporabljajo 12-pulzne enote pretvornika, sestavljene iz povezav trifaznega mostu (dvosmernih), vendar ne zajema večterminalske HVDS sisteme oddajanja. Vendar so obravnavani določeni vidiki vzporednih pretvornikov in vzporednih vodov dvoterminalskega sistema. Za pretvornike se predvideva, da kot premostitvene ročice uporabljajo tristorske ventile , z zaporami brez vrzeli iz kovinskih oksidov za usklajevanje izolacije in da imajo kapaciteto pretoka energije v obe smeri. Diodni ventili niso upoštevani v tem poročilu. Zgolj vodovno komutirani pretvorniki so zajeti v tem poročilu, vključno z konfiguracijami tokov kondenzatorsko komutiranih pretvornikov. Splošne zahteve za polprevodne vodovno komutirane pretvornike so podane v IEC 60146-1-1, IEC 60146-1-2 in IEC 60146-1-3. Napetostno napajani pretvorniki niso obravnavani.
