| 摘 要： | 采用同塔多回架空线路方式是解决输电走廊紧张矛盾的根本措施之一.针对220 kV同塔四回线路的电磁环境问题,采用CDEGS软件包进行了仿真研究,计算了输电线路在不同导线排列方式下地面上方1.5 m处的工频电场、工频磁场、无线电干扰、可听噪声值,并根据工频电场的限值划定了线路走廊的宽度;通过对计算结果的比较分析得出了导线的最优排列方式,并提出了减小线路周围工频电场的措施;仿真结果表明,影响220 kV同塔线路电磁环境的主要因素是工频电场. |

| Abstract: | With the rapid development of electric engineering in our country,the electric grid becomes more and more compact.The right way of power transmission line and the used area become important problems to the power transmission line constructing.Using CDEGS software package,the electromagnetic environment under 220 kV four circuits on one tower transmission line was simulated.The power frequency electric field and magnetic field,radio interference(RI) and audible noise(AN) were examined systematically under di... |
