HVDC for the long run
The principal application for dc transmission in the U.S., at present, is from mine-mouth or hydro generating plants to urban areas. However, in the future, it will be extended to include nuclear plants. There is also the coming possibility of strong regional interconnections (east--west, north--south), some of which may be HVDC. Overhead dc transmission has an economic advantage over similar ac transmission for distances as short as 600 km; and a bipolar dc line is essentially equivalent to two ac circuits. Most applications in the U.S. will be at +-400 kV and above; the need for +-600 kV exists today, and the technology is available. Toward the end of the 1970s, this voltage requirement will rise to +-800 kV; and there is little doubt that the technology will be available. The use of still higher voltages could occur in the 1980s. As the direct result of the significant effort now underway in the development of new and improved HVDC equipment, there is no doubt that HVDC will play an increasingly important role in U.S. and world power systems of the future.
