基于APDL的特高压直流输电线路标称场强数值计算分析

介绍了ANSYS软件仿真的基本原理,通过APDL快速建立了由输电线路的高度、极间距、分裂导线数等不同参数变化而变化的仿真模型,能够更加快捷方便地对特高压直流输电线路下标称场强的分布情况进行仿真.仿真结果表明,地面标称场强的强度在两条输电线路的中心处为零,然后往两极导线方向迅速增加并于导线外侧18 m附近达到最大值,最后趋向于零.;The basic principles of ANSYS software simulation are introduced. Different model parameters of the transmission line's height,pole spacing and the number of bundled conductors can be changed by APDL language and the simulation of UHVDC transmission line's nominal field strength will be more efficient and convenient. The simulation results show the electric field strength is smallest at the center and increases very rapidly in the direction of the outside conductor. The maximum nominal field strength appears in the 12 meters, and then drastically reduces to 0
