| Abstract: | The strategy and measures for solving the power frequency electromagnetic environment problems in developing their UHV transmission lines in former USSR, Japan and the US are briefly introduced and analyzed. Based on the construction and operation experiences gained from 500kV transmission lines in China a new phase conductor configuration scheme (compact line with verse triangle configuration of phase conductors) is proposed. Distributions of power frequency electric field and magnetic field for the above mentioned three types of UHV transmission lines abroad and that of the proposed scheme to be developed are calculated under the same control condition. The obtained results should be helpful in choosing and determining the phase conductor configuration and the type of tower of the first UHV lines in China. |
