UHV A.C. transmission: Technology and prospects

Abstract

At the beginning of the 70`s, UHV transmission was regarded as imminent in many countries in view of the expected concentration of generating units (possibly of the nuclear type and grouped together in a few large plants, each of several GW), and research projects were therefore launched in the U.S.A., Canada, Italy, Japan, USSR, etc. Nowadays, the expected introduction of UHV transmission seems remote due to the slowdown in electricity growth and to the tendency towards distributed generation. Nevertheless, there are exceptions: the 1,200 kV 2,400 km-long transmission system in operation in Siberia-Kazahkstan-Urals, and the 1,100 kV 200 km double-circuit line under construction in Japan (which will, however, be operated at 500 kV up to the end of the century). In addition, in Italy, the research programme of a 1000 kV project has now been completed and a 1,050 kV pilot plant is under construction in Tuscany, consisting of a short 1,050kV line and a 420/1,050 kV 1,200 MVA substation. The technology of UHV AC transmission has therefore been proved effective and may represent an available option for the power systems of the next century. From the power system planning point-of-view, UHV`s favourable characteristics lie in the possibility of transmitting  More>>
