Reliability and availability evaluation of HVDC systemsWhat is PD IEC TR 62672 HVDC systems about? PD IEC TR 62672 is an international standard that discusses the reliability and availability evaluation of HVDV systems. HVDC allows power transmission between AC transmission systems that are not synchronized. PD IEC TR 62672 applies to all line commutated and voltage sourced high voltage direct current (HVDC) transmission systems used for power exchange in utility systems. The purpose of PD IEC TR 62672 is
