This International Standard defines terms for high-voltage direct current (HVDC) power transmission systems and for HVDC substations using electronic power converters for the conversion from a.c. to d.c. or vice versa.
This standard is applicable to HVDC substations with line commutated converters, most commonly based on three-phase bridge (double way) connections (see figure 2) in which unidirectional electronic valves, e.g. semiconductor valves, are used.dition 2.2 2015-07 CONSOLIDATED VERSION VERSION CONSOLIDéE colour inside Terminology for high-voltage direct current (HVDC) transmission Terminologie pour le transport d'énergie en courant continu à haute tension (CCHT) IEC 60633:1998-12+AMD1:2009-05+AMD2:2015-07 CSV(en-fr) THIS PUBLICATION IS COPYRIGHT PROTECTED Copyright ？ 2015 IEC, Geneva, Switzerland All rights reserved.
