Long distance HVDC lines carrying hydroelectricity from Canada's Nelson River to this converter station where it is converted to AC for use in southern Manitoba's grid. A high-voltage direct current (HVDC) electric power transmission system uses direct current (DC) for electric power transmission, in contrast with the more common alternating current (AC) transmission systems. [1]
An HVDC converter converts electric power from high voltage alternating current (AC) to high-voltage direct current (HVDC), or vice versa. HVDC is used as an alternative to AC for transmitting electrical energy over long distances or between AC power systems of different frequencies. [ 1 ]
Electric power transmission through interconnectors using high-voltage direct-current (HVDC) involves usually two converter stations and a transmission line. Generally overhead lines are used, but an important class of HVDC projects use submarine power cables. A back-to-back station has no transmission line and joins two separate AC grids at a ...
1954, the first HVDC submarine power cable (non-experimental) [18] Gotland 2 and 3 installed in 1983 and 1987. HVDC Inter-Island: South Island: Cook Strait: North Island: 350: 40 km (25 mi) 1965: between the power-rich South Island (much hydroelectric power) of New Zealand and the more-populous North Island. HVDC Italy-Corsica-Sardinia (SACOI ...
It is the first HVDC Light transmission system project, to use ±200 kV cables. The cables and converter stations were provided by ABB . [ 1 ] [ 6 ] The project was financed by a €300 million loan from the European Investment Bank , capital investments from commercial banks, EirGrid equity and a €110 million grant from the European Commission.
The thyristors, supplied by the German HVDC consortium (Siemens, AEG and Brown Boveri) used water cooling [10] for the first time in an HVDC project. Until that time, the relatively few HVDC schemes using thyristors had used either air cooling or, as on the Cahora Bassa project supplied by the same consortium, oil-cooling.
An HVDC converter station (or simply converter station) is a specialised type of substation which forms the terminal equipment for a high-voltage direct current (HVDC) transmission line. [1] It converts direct current to alternating current or the reverse.
The HVDC Troll is a bipolar high-voltage direct current (HVDC) electric power transmission line for the supply of the gas compressor station on the offshore construction work Troll A platform. It consists of dual set of a 68-kilometre (42 mi) long bipolar submarine cable designed for ±60 kV between the inverter at the Troll A platform and the ...
