List of HVDC projects
This 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.
Legend
Line type:
- Thury = Series-connected generators as designed by René Thury
- Merc = Mercury-arc valve rectifier and inverter
- Thyr = Thyristor rectifier and inverter
- IGBT = Insulated Gate Bipolar Transistors
