Annotation of standard text IEC 62501-ed.2.0 :
IEC 62501:2024 applies to self-commutated converter valves, for use in a three-phase bridge voltage sourced converter (VSC) for high voltage DC power transmission or as part of a back-to-back link, and to dynamic braking valves. It is restricted to electrical type and production tests. This document can be used as a guide for testing of high-voltage VSC valves used in energy storage systems (ESS). The tests specified in this document are based on air insulated valves. The test requirements and acceptance criteria can be used for guidance to specify the electrical type and production tests of other types of valves. This edition includes the following significant technical changes with respect to the previous edition: a) Conditions for use of evidence in lieu are inserted as a new Table 1; b) Test parameters for valve support DC voltage test, 7.3.2, and MVU DC voltage test, 8.4.1, updated; c) AC-DC voltage test between valve terminals, Clause 9, is restructured and alternative tests, by individual AC and DC voltage tests, added in 9.4.2; d) Partial discharge test in routine test program is removed; e) More information on valve component fault tolerance, Annex B, is added; f) Valve losses determination is added as Annex C. LIEC 62501:2024 sapplique aux valves a convertisseur auto-commute, concues pour etre utilisees dans un convertisseur de source de tension (VSC) en pont triphase pour le transport denergie en courant continu a haute tension ou dans une liaison dos-a-dos, ainsi quaux valves a freinage dynamique. Elle est limitee aux essais de type electriques et de serie. Le present document peut servir de guide pour les essais des valves a VSC a haute tension utilisees dans les systemes de stockage denergie (ESS). Les essais specifies dans le present document sont bases sur des valves isolees par lair. Les exigences dessai et les criteres dacceptation peuvent servir de guide pour specifier les essais de type electriques et de serie dautres types de valves. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: a) un nouveau tableau relatif aux conditions dutilisation de la substitution de preuve (Tableau 1) a ete insere; b) les parametres dessai relatifs a lessai de support de valve sous tension continue (7.3.2) et a lessai de MVU sous tension continue (8.4.1) ont ete mis a jour; c) lArticle 9 concernant lessai sous tension alternative-continue entre les bornes de valve a ete reorganise et des variantes ont ete ajoutees en 9.4.2 pour les essais individuels sous tension alternative et continue; d) lessai de decharge partielle a ete supprime du programme des essais individuels de serie; e) des informations complementaires relatives a la tolerance aux pannes des composants de valve ont ete ajoutees a lAnnexe B; f) la determination des pertes de valve a ete ajoutee a lAnnexe C.
