Development of totally metal enclosed SF/sub 6/ gas insulated HVDC converter station
HVDC power transmission has increasingly acquired practical importance and a number of large-scale projects such as the 2000-MW system connecting Britain and France and the 6000-MW system in Italy and Brazil are under way. In Japan, three HVDC installations are in operation, and a stepped-up effort is directed toward the advancement of dc technology with emphasis on application to long-distance bulk power transmission and interconnection. The development of HVDC power system at voltages up to +/-500 kV is described. In the development project, the major aims were set to develop a compact and economical converter station having high reliability - at least as high as that in ac power transmission. It was concluded that compressed SF/sub 6/ gas insulation of the equipment in a converter station is a potential solution to meet the requirements, and the first step in the project has been completed. Ideas on the new converter station, gas insulation of dc equipment, cooling technique, dc ZnO varistor to protect thyristors individually, and some other results of the project together with a future view on the new technologies are presented.
