(Main)Static VAR compensators (SVC) - Testing of thyristor valves
Static VAR compensators (SVC) - Testing of thyristor valves
IEC 61954:2011 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 standard apply both to single valve units (one phase) and to multiple valve units (several phases). This edition includes the following significant technical changes with respect to the previous edition: a) Definitions of terms 'thyristor level', 'valve section', 'valve base electronics' and 'redundant thyristor levels' have been changed for clarification; b) Conditions of testing thyristor valve sections instead of a complete thyristor valve have been defined; c) The requirement has been added that if, following a type test, one thyristor level has become short-circuited, then the failed level shall be restored and this type test repeated; d) The time period of increasing the initial test voltage from 50 % to 100 % during type a.c. dielectric tests on TSC, TCR or TSR valves has been set equal to approximately 10 s; e) The duration of test voltage Uts2 during type a.c.-d.c. dielectric tests between TSC valve terminals and earth as well as the duration of test voltage Utvv2 during dielectric tests between TSC valves (for MVU only) has been changed from 30 min to 3 h; f) The reference on the number of pulses per minute of the periodic partial discharge recorded during a.c.-d.c. dielectric tests on TSC valves and exceeding the permissible level has been deleted.
Statische Blindleistungskompensatoren (SVC) - Prüfung von Thyristorventilen
Compensateurs statiques de puissance réactive (SVC) - Essais des valves à thyristors
La CEI 61954:2011 définit les essais de type, les essais de production et les essais facultatifs des valves à thyristors utilisées dans les bobines d'inductance commandées par thyristors (TCR), les bobines d'inductance commutées par thyristors (TSR) et les condensateurs commutés par thyristors (TSC) qui font partie des compensateurs statiques de puissance réactive (SVC) pour des applications de système de puissance. Les exigences de la présente norme s'appliquent tant aux unités à valve unique (monophasées) qu'aux unités à valves multiples (polyphasées). Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) Les définition des termes 'niveau de thyristor', 'section de valve', 'électronique de base de valve', 'niveaux de thyristors redondants' ont été clarifiées; b) Les conditions pour les essais des sections de valves de thyristors à la place des thyristors complets ont été définies; c) Une exigence a été ajoutée afin que, suite à un essai de test, si un niveau de thyristor a été court-circuité, alors le niveau défaillant puisse être restauré et cet essai de type répété; d) La période de temps d'accroissement de la tension d'essai initiale de 50 % à 100 % pendant l'essai de type diélectrique en courant alternatif sur les valves TSC, TCR ou TSR, a été fixée à approximativement 10 s; e) La durée de l'essai de tension Uts2 pendant l'essai de type diélectrique c.a.-c.c. entre des bornes de valves TSC et la terre, ainsi que la durée de la tension d'essai Utvv2 pendant les essais diélectriques entre valves TSC (pour les MVU uniquement) a été modifiée de 30 min à 3 h; f) Suppression de la référence au nombre d'impulsions par minute de décharge partielle périodique enregistrées pendant les essais diélectriques c.a.-c.c. sur les valves TSC et dépassant le niveau admissible.
Statični kompenzatorji jalove energije (var) - Preskušanje tiristorskih elektronk
Ta mednarodni standard določa tipe, proizvodnjo in opcijske preskuse tiristorskih elektronk, uporabljenih v tirstorsko nadzorovanih reaktorjih, tiristorsko preklopljenih reaktorjih (TSR) in tiristorsko preklopljenih kondenzatorjih (TSC), ki tvorijo del statičnih kompenzatorjev VAR (SVC) za uporabo pri sistemih napajanja. Zahteve standarda veljajo za enote z eno elektronko (enofazne) in za enote z več elektronkami (večfazne). Točke 4 do 7 podrobno opisujejo tipske preskuse, tj. preskuse, ki se izvajajo za potrditev, da načrt elektronke izpolnjuje nekatere zahteve. Točka 8 zajema proizvodne preskuse, tj. preskuse, ki se izvajajo za potrditev pravilne proizvodnje. Točki 9 in 10 podrobno opisujeta opcijske preskuse, tj. dodatne preskuse poleg tipskih in proizvodnih preskusov.

levels” have been changed for clarification.
b) Conditions of testing thyristor valve sections instead of a complete thyristor valve have been defined.

circuited, then the failed level shall be restored and this type test repeated.
d) The time period of increasing the initial test voltage from 50 % to 100 % during type a.c. dielectric tests
on TSC, TCR or TSR valves has been set equal to approximately 10 s.
e) The duration of test voltage Uts2 during type a.c.-d.c. dielectric tests between TSC valve terminals and
