The HVDC Cross-Channel ((フランス語:Interconnexion France Angleterre)) is the name given to two different high voltage direct current (HVDC) interconnectors that operate or have operated under the English Channel between the continental European and British electricity grids. The first Cross-Channel link was a 160 MW link completed in 1961 and decommissioned in 1984, while the second was a 2000 MW link completed in 1986. The current 2000 MW link, like the original link, is bi-directional and France and Britain can import/export depending upon market demands. ==160 MW system (1961)== The first HVDC Cross-Channel scheme was built by ASEA and went into service in 1961 〔Compendium of HVDC schemes, CIGRÉ, (Compendium of all HVDC projects )〕 between converter stations at Lydd in England (next to Dungeness Nuclear Power Station) and Echinghen, near Boulogne-sur-Mer, in France. This scheme was equipped with Mercury arc valves, each having four anodes in parallel.〔Cory, B.J., Adamson, C., Ainsworth, J.D., Freris, L.L., Funke, B., Harris, L.A., Sykes, J.H.M., High voltage direct current converters and systems, Macdonald & Co. (publishers) Ltd, 1965, p175–218.〕 In order to keep the disturbances of the magnetic compasses of passing ships as small as possible, a bipolar cable was used. The cable had a length of and was operated symmetrically at a voltage of ±100 kV and a maximum current of 800 amperes. The maximum transmission power of this cable was 160 megawatts (MW). The cable was built by ABB Group. Given that the cable was laid on the surface of the seabed it was prone to being fouled by fishing nets, causing damage. Whilst repairs were undertaken there was considerable down time on the circuit resulting in a loss of trading. Indeed, by 1984 the circuit was disconnected from the Main Transmission System. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「HVDC Cross-Channel」の詳細全文を読む スポンサード リンク
