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.

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 ...
The two major and three minor NERC interconnections, and the nine NERC Regional Reliability Councils. 735 kV substation near the Robert-Bourassa generating station. Hydro-Québec's electricity transmission system (also known as the Quebec interconnection) is an international electric power transmission system centred in Quebec, Canada.
HVDC Cross-Channel: French mainland: English Channel: England: 270: 73 km (45 mi) 1986: very high power cable (2000 MW) [citation needed] HVDC Gotland: Swedish mainland: Baltic Sea: Swedish island of Gotland: 150: 98 km (61 mi) 1954: 1954, the first HVDC submarine power cable (non-experimental) [18] Gotland 2 and 3 installed in 1983 and 1987 ...
HVDC cable termination and DC smoothing reactor on the Baltic Cable HVDC link. The direct current equipment often includes a coil (called a reactor) that adds inductance in series with the DC line to help smooth the direct current. The inductance typically amounts to between 0.1 H and 1 H. The smoothing reactor can have either an air-core or an ...
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 ]
Path 27, also called the Intermountain [c] or the Southern Transmission System (STS), [4] [5] [6] is a high-voltage direct current (HVDC) electrical transmission line running from the coal-fired Intermountain Power Plant near Delta, Utah, to the Adelanto Converter Station at Adelanto, California, in the Southwestern United States.
The Caithness–Moray Link is a 160 km (100-mile) HVDC submarine power cable beneath the Moray Firth in Scotland, linking Spittal in Caithness and Blackhillock in Moray. Constructed by Scottish & Southern Electricity Networks , it is capable of transmitting up to 1,200 MW of power. [ 2 ]
