Statische Blindleistungskompensatoren (SVC) - Prüfung von Thyristorventilen (IEC 61954:2011 + A1:2013); Deutsche Fassung EN 61954:2011 + A1:2013
Overview
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, that is, tests which are carried out to verify that the valve design meets the requirements specified. Clause 8 covers the production tests, that is tests which are carried out to verify proper manufacturing. Clauses 9 and 10 detail optional tests, that is tests additional to the type and production tests. Amendment A1 contains as the significant modification the reduction of the safety factor ks13 that shall be applied on the peak value of the highest periodic overvoltage, from ks13 = 1,3 to ks13 = 1,15. The responsible committee is DKE/K 331 "Leistungselektronik" ("Power electronics") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
