综合考虑辐射和传导骚扰的变电站内5G基站部署选址方法研究

Research on 5G Base Station Deployment and Location Method in Substation Considering Radiation and Conduction Disturbance

随着变电站内5G应用的普及,越来越多的5G基站需要建设在变电站内。5G基站内的通信设备面临复杂电磁环境的影响,外置天线的存在对5G基站的电磁防护提出挑战。文章分析变电站对5G基站的电磁骚扰因素和计算方法,以某500 kV变电站简化模型为对象阐述分析过程,并讨论主要影响因素、抑制方法和选址建议,为提升变电站内二次设备与5G通信设备的电磁兼容性及5G通信设备在变电站内的部署提供参考。

With the popularity of 5G applications in substations,more and more 5G base stations need to be built in substations.The communication equipment in 5G base station is affected by complex electromagnetic environment.The existence of external antenna challenges the electromagnetic protection of 5G base station.This paper analyzes the electromagnetic disturbance factors and calculation methods of the substation to 5G base station,expounds the analysis process with a simplified model of a 500 kV substation as the object,and discusses the main influencing factors,suppression methods and site selection suggestions,so as to provide reference for improving the electromagnetic compatibility between secondary equipment and 5G communication equipment in the substation and the deployment of 5G communication equipment in the substation.
