Electromagnetic Environment of 1000kV UHV Transmission Line

Shao Fang-yin

Abstract

Comparison and analysis on transmission corridor for 1000 kV transmission line and those for five-circuit 500 kV transmission lines as well as the two electromagnetic environment are performed. Analysis results show that under the same transmitted power,the width of transmission corridor for 1000 kV transmission line can be narrowed down in the range from 98m to 110m than total width of corridors for five-circuit 500 kV transmission lines;meanwhile the effected ranges of power frequency electric field and magnetic field,radio interference and audible noise are evidently decreased.
