Performance of high-voltage direct current (HVDC) systems with line-commutated converters - Part 1: ...
IEC/TR 60919-1:2010+A1:2013+A2:2017 provides general guidance on the steady-state performance requirements of HVDC systems. It concerns the steady-state performance of two-terminal HVDC systems utilizing 12-pulse converter units comprised of three-phase bridge (double- way) connections, but it does not cover multi-terminal HVDC transmission systems. Both terminals are assumed to use thyristor…
