摘要
受通信负载随机性与间歇性的影响,5G基站负荷表现出不确定性。为解决大规模5G基站接入后配电网扩展规划难度增大的问题,本文首先根据5G基站的通信物理设备组成,推导出5G基站在给定时间内的能耗计算模型。在此基础上,分析了不同建筑群的用户分布、不同建筑群内用户接入特性和不同业务的流量特性对5G基站能耗大小的影响,建立了5G基站的有功负荷概率分布模型。在充分考虑5G基站广泛接入配电网后,提出了计及5G基站负荷概率特性的配电网扩展规划方法。最后,对实际配电网络进行了考虑5G基站接入的负荷能耗和扩展规划的仿真分析,验证了所建模型的有效性。
Affected by the randomness and intermittentness of communication load,the load of 5G base stations shows uncertainty.In order to solve the problem of increasing difficulty in planning the expansion of the distribution network after the large-scale 5G base station is connected,this paper first derives the energy consumption calculation model of the 5G base station in a given time based on the composition of the communication physical equipment of the 5G base station.On this basis,the influences of the wide distribution of mobile phone users,the characteristic of different cellular data and the access characteristics of users in different areas on the cellular data are analyzed,and the active load probability distribution model of 5G base stations is established.The expansion planning model of distribution network can be further established considering the probability characteristics of 5G base stations load.Finally,a simulation analysis of an actual power distribution network considering the load energy consumption and expansion planning of 5G base station access was carried out,and the validity of the built model was verified.
