摘要
分析了同走廊输电线路架设参数、土壤参数以及电力系统运行参数对输电线路电磁耦合的影响。利用EMTP软件对同走廊架设500kV双回路交流线路与1 000 kV特高压交流线路建模,然后结合线路具体参数分析了输电走廊各参数对1 000 kV输电线路中电磁感应分量的影响,最后得到了同走廊架设高压输电线路感应分量随走廊各参数的变化规律,为共用走廊中输电线路架设安全距离的选择提供了参考。
This paper analyzes the effects on the electromagnetic interference among transmission lines in joint-use corridor caused by various parameters including erection parameters, soil parameters and power system operation parameters. Based on EMTP software, a multi-conductor transmission line model is established consisting of 500 kV double-circuit AC transmission lines and 1 000 kV one-circuit AC transmission lines. Thereby the effects of various parameters on the electromagnetic induction components of the 1 000 kV AC transmission lines are analyzed, and the general rules of induction components among transmission lines changing with different parameters are obtained. This research aims to provide an insight into how to decide on the safe erection distance between transmission lines in jointuse corridors.
