McNeill HVDC Back-to-back station

McNeill HVDC Back-to-back station is an HVDC back-to-back station at 50°35'56"N 110°1'25"W, which is used for the interconnection of the power grids of the canadian provinces Alberta and Saskatchewan and went in service in 1989. McNeill HVDC back-to-back station can transfer a maximum power of 150 MW at a voltage of 42 kV. The station, which was built by Alstom, is unique as no smoothing reactor, a part which most engineers consider as an absolutely must at HVDC plants, is used. The thyristor valves of the station are cooled by an aqueous ethylene/glycol solution, which does not freeze at temperature of -50°C.
