摘　　要：高压交流输电线路无线电干扰水平是线路电磁环境的指标之一。采用激发函数法计算了双回交流线路不同相序、不同线路间距等情况下无线电的干扰水平。计算结果表明:对于垂直排列的双回交流线路,同相序排列对应的无线电干扰水平最低;不同相序排列无线电干扰水平相差不大;对于任意多回路,无线电干扰水平的计算必须借助合适的软件。The radio interference level from high-voltage power transmission line is one of the indices to evaluate electromagnetic environment of transmission line. By use of excitation function the radio interference levels from double-circuit transmission line under different phase sequences and different spacing between transmission lines are calculated. Calculation results show that for vertically arranged double-circuit transmission line, the radio interference level under the same phase sequence arrangement is the lowest; there is no evident difference among the radio interference levels corresponding to double-cuicuit transmission line with different phase sequence arrangement; for arbitrary number-circuit transmission line, it is necessary to calculate radio interference level by appropriate software.
