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 ...
The two-level converter is the simplest type of three-phase voltage-source converter [29] and can be thought of as a six pulse bridge in which the thyristors have been replaced by IGBTs with inverse-parallel diodes, and the DC smoothing reactors have been replaced by DC smoothing capacitors. Such converters derive their name from the fact that ...
Most notably, the McNeill station was the first HVDC installation to dispense with the DC smoothing reactor, a component which most engineers consider as an absolute must at HVDC plants. Even today, only a small number of back to back HVDC stations (and no point-to-point transmission schemes) have been built without DC smoothing reactors.
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.

The New Zealand Inter-Island HVDC link is a long distance bipolar HVDC "Classic" transmission scheme that uses overhead lines and submarine cables to connect between the South and North Islands. It uses thyristor -based line-commutated converters at each end of the link for rectifying and inverting between AC and DC.
The DC line has smoothing reactors and surge arrester capacitors at each station. Northeast of Apollo Converter Station the poles of HVDC Cahora Bassa undercross several 400 kV AC lines at 25°54'58"S 28°16'46"E respectively 25°54'57"S 28°16'51"E in such a low altitude that the area under the line may not be walked on and is fenced in [1] .
The EMT-type software named EMTDC/PSCAD is currently developed and maintained by Manitoba HVDC Research Center. The real-time simulation tool named RTDS is commercialized by RTDS Technologies Inc. Hydro-Québec also developed a real-time EMT solver named Hypersim.
