摘要
5G通信基站耗电量较大,引入分布式供电(DG)单元能对其进行一定的电能补充,但DG单元易受气象条件的影响,导致通信基站节能供电系统运行不稳定。为提高通信基站节能供电系统运行的稳定性,提出了一种基于直流母线电压信息自动切换的控制策略,系统内各单元可根据当前直流母线电压状态实现并网、孤岛模式的无缝切换。仿真结果表明,所提控制策略能够维持通信基站节能供电系统稳定运行,实现不间断供电,为未来设计节能型5G通信基站供电系统提供了一定理论依据。
The 5G communication base station consumes a lot of power,and it can be supplemented to a certain ex-tent by adding a distributed generation(DG)unit.However,DG unit is easily affected by meteorological conditions,which leads to unstable operation of energy-saving power supply system.In order to improve the stability of energy-saving power supply system of communication base station.an automatic switching control strategy based on DC bus voltage in-formation is studied in this paper.Each unit in the system can realize seamless switching of grid-connection mode and is-landing mode according to the current DC bus voltage state.Simulation results show that the proposed control strategy can maintain the stable operation of energy-saving power supply system and realize uninterrupted power supply,which provides a theoretical basis for design of energy-saving 5G communication base station power supply system in the future.
