区域输电线路共享铁塔搭载天线信号覆盖及资源评估

Evaluation of Signal Coverage of Mounted Antenna and Communication Resources of Shared Tower for Regional Transmission Lines

随着5G通信技术的发展,大量电力铁塔作为共享铁塔用于架设5G通信基站。为了给电力铁塔共享规划提供参考依据,提出计算区域输电线路共享铁塔搭载天线信号覆盖面积及定量评估通信资源的"点-线-面"方法。首先,研究单个共享电力铁塔架设5G通信基站所能提供的通信资源,根据铁塔呼称高和天线挂高计算单塔通信信号覆盖面积;然后,利用带宽廊道计算方法,得到整条输电线路共享铁塔通信信号覆盖面积;最后,去除多种重复的信号覆盖范围,推导得到区域内所有输电线路共享铁塔通信信号覆盖总面积计算公式。利用"点-线-面"方法计算通信信号覆盖面积,能够定量得到区域内所有输电线路共享铁塔提供的通信资源,有利于为电网公司输电铁塔的共建共享规划提供理论依据。

With the development of 5G communication,a large number of electric pylons are used as shared pylons to set up 5G communication base stations.In order to provide a reference for power tower sharing planning,a"point-line-area"method is proposed to calculate the area covered by the antenna signals of regional transmission line shared tower and to quantitatively evaluate the communication resources.Firstly,the communication resources provided by a single 5G communication base station on a shared electric power tower are studied,and the communication signal coverage area of a single tower is calculated according to the nominal height of the tower and the hanging height of the antenna;secondly,the signal coverage area of the shared tower of the entire transmission line is concluded through bandwidth corridor calculation method;finally,a calculation formula for total signal coverage area calculation formula of signal coverage of shared towers of transmission lines in the region is derived by eliminating duplicated signal coverage areas.Calculation of the communication signal coverage area using the"point-line-area"method can quantitatively obtain the communication resources provided by shared tower of all transmission lines in the region and provide theoretical basis for construction and sharing planning of transmission tower of power grid enterprises.
