Impact of HVDC Stations on Protection of AC Systems

Operating experience has shown that in most cases the impacts of the HVDC system on the protection of adjacent HVAC systems are negligible, while in some special cases the HVDC system may bring about different fault characteristics to the adjacent HVAC system and influence the operation of the HVAC protection. The TB analyses the phenomenon in HVAC systems brought about by HVDC transmission systems and the resulting impacts on the operation of HVAC protection, and provides guidance on designing a proper HVAC protection system in the presence of adjacent HVDC systems.
