摘要
变电站是电网系统的枢纽,随着5G技术的兴起,越来越多的5G基站被规划在智能变电站内。然而变电站内输电线路产生的工频电磁骚扰极大影响了5G基站中通信设备的部署,在这种情况下,研究变电站内输电线路工频电磁场对5G基站的影响尤为重要。本文对某实际变电站进行物理建模,开展站内工频电磁场的计算。仿真模拟了该站220 kV和500 kV输电线路的工频电磁场环境,并与实测结果进行对比验证了变电站模型的正确性;通过对不同高度下输电线路工频电磁场结果进行分析,得出了5G基站的部署范围。本文研究可为典型智能变电站内5G基站的部署提供理论参考。
The substation is the hub of the power grid system.With the emergence of 5G technology,an increasing number of 5G base stations are being planned within substations.However,the power frequency electromagnetic interference generated by the power transmission lines inside substations significantly impacts the deployment of communication equipment in 5G base stations.In this scenario,studying the effects of power frequency electromagnetic fields within substations on 5G base stations is particularly crucial.This paper physically modeled a substation,calculating the power frequency electromagnetic fields within the station.Simulations were conducted to model the power frequency electromagnetic field environment of the 220 kV and 500 kV transmission lines at the station,and the accuracy of the substation model was verified through comparison with measured results.Finally,analysis of the power frequency electromagnetic fields of the transmission lines at different heights led to the determination of the deployment range of 5G base stations.This study provides theoretical references for the deployment of 5G base stations within typical substations.
