Static VAR compensators (SVC) - Testing of thyristor valves

This International Standard 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). Clauses 4 to 7 detail the type tests, i.e. tests which are carried out to verify that the valve design meets the requirements specified. Clause 8 covers the production tests, i.e. tests which are carried out to verify proper manufacturing. Clauses 9 and 10 detail optional tests, i.e. tests additional to the type and production tests.

Static VAR compensators (SVC) - Testing of thyristor valves

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.

This European Standard was approved by CENELEC on 2011-05-26. CENELEC members are bound to comply
with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard
the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and notified
to the Central Secretariat has the same status as the official versions.

CENELEC members are the national electrotechnical committees of Austria, Belgium, Bulgaria, Croatia, Cyprus,
the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy,
Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia,

Foreword
The text of document 22F/217/CDV, future edition 2 of IEC 61954, prepared by SC 22F, Power
electronics for electrical transmission and distribution systems, of IEC TC 22, Power electronic systems
and equipment, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as
EN 61954 on 2011-05-26.
This European Standard supersedes EN 61954:1999 + A1:2003.
EN 61954 :2011 includes the following significant technical changes with respect to
EN 61954:1999 + A1:2003:
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.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN and CENELEC shall not be held responsible for identifying any or all such patent
rights.
The following dates were fixed:

– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2012-02-26
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2014-05-26
Annex ZA has been added by CENELEC.
