摘要
采用CDEGS软件包对±800 kV特高压直流输电线路的电磁环境进行了仿真研究。分析了极导线水平排列的±800 kV特高压直流输电线路的标称电场、合成电场、无线电干扰(RI)和可听噪声(AN)的总体水平。讨论了线路参数,包括极导线对地高度、极间距、子导线截面积等对特高压直流输电线路的电磁环境参数的影响。对海拔高度变化和单极运行方式等的影响也进行了分析。
The electromagnetic environmental effect of ±800 kV UHVDC transmission lines is numerically investigated in this paper. The CDEGS software package is employed for the numerical simulation. Pole conductor horizontal arranged ±800 kV UHVDC transmission lines models are studied. The distributions of nominal electric field, total electric field, radio interference and audible noise are calculated. The influence of the height of phase conductors, wire spacing, the sectional area of the subconductors on the above parameters are analyzed. The effect of height above sea level and single pole operation mode are also investigated.
