Performance of high-voltage direct current (HVDC) systems with line-commutated converters - Part 1: ...
IEC TR 60919-1:2020(E) provides general guidance on the steady-state performance requirements of high-voltage direct current (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 multiterminal HVDC transmission systems. Both terminals are assumed to…
