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]
This makes voltage-source converters much easier to connect into a Multi-terminal HVDC system or "DC Grid". [27] HVDC systems based on voltage-source converters normally use the six-pulse connection because the converter produces much less harmonic distortion than a comparable LCC and the twelve-pulse connection is unnecessary.

450kV HVDC line (at right), on south side of Autoroute 20 east of the Nicolet station near Sainte-Eulalie, Quebec.. The Quebec – New England Transmission (officially known in Quebec as the Réseau multiterminal à courant continu (RMCC) [1] and also known as Phase I / Phase II [2] and the Radisson - Nicolet - Des Cantons circuit, [3] and known in New England as the Northern Pass) is a long ...
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 ...
HVDC electrodes are used in most bipolar thyristor-based line-commutated converter (LCC) HVDC transmission systems as a means to improve the reliability of the entire system while also reducing the DC voltage and current ripples. In the event that one of the poles in the bipolar system is faulted, the current path will switch to ground return ...
