HVDC Transmission Systems are a mature technology used worldwide. A brief history,
principles of Line Current commutated (LCC) and voltage sourced (VSC) HVDC systems
and look at the future are presented. Reasons and comparisons between the selection of
HVDC versus Ac technologies as well as differences in HVDC control and protection
systems will round out this talk.
