List of HVDC projects
Encyclopedia
The following is a list of notable high voltage direct current power transmission projects.

HVDC projects for long-distance transmission have two (or rarely, more) converter stations and a transmission line interconnecting them. Generally overhead lines are used for interconnection, but an important class of HVDC projects use submarine power cables. A back-to-back station has no transmission line and connects two AC grids at different frequencies or phase counts. Historical HVDC systems used the Thury system of motor-generators but these have all been made obsolete by later developments such as mercury-arc valves, thyristors, and IGBT power transistors.

Type key

  • B2B = "Back to Back" HVDC
  • IGBT = Insulated Gate Bipolar Transistors
  • Thury = Series-connected generators according René Thury
    René Thury
    René Thury was a Swiss pioneer in electrical engineering. He was known for his work with high voltage direct current electricity transmission and was known in the professional world as the "King of DC." -Biography:...

  • Merc = Mercury-arc valve rectifier and inverter
  • Thyr = Thyristor
    Thyristor
    A thyristor is a solid-state semiconductor device with four layers of alternating N and P-type material. They act as bistable switches, conducting when their gate receives a current trigger, and continue to conduct while they are forward biased .Some sources define silicon controlled rectifiers and...

     rectifier and inverter
  • To find by location, sort by "Converter Station 1", and look for the country name of either end of the connection that sorts first. If available, coordinates of stations are also listed.
  • "Cable" means undersea or underground cable.
  • "Pole" means overhead wires.
