5G基站场景下的高压直流远供关键技术与经济模式OA北大核心

Compared with 4G communication,5G communication uses key technologies such as large-scale anten-nas,ultra-dense networking,and high-frequency communication to greatly improve its performance,resulting in increased power consumption of single 5G base stations and multiple sites.As a result,the power supply requirements are also changed.At present,there are two kinds of power supply forms which can meet the new power supply requirements,i.e.,near supply and HVDC remote supply.Aimed at the HVDC remote supply,the power supply architecture and key tech-nology are sorted out,and a feasible operation mode is proposed by comprehensively considering the operating invest-ment cost in the economic mode of peak-shaving and valley-filling,the busy and idle periods of 5G base station service load,and the peak-valley time-of-use electricity price.On the basis of the construction which has already been invested under the HVDC remote supply scheme,the investment cost is small,and the economic benefit is obtained by using the time-of-use electricity price difference between peak and valley periods,thus reducing the power consumption cost of base stations to a certain degree.Finally,the development of 5G base station power supply is forecasted,providing refer-ence for the research or design of its power supply.
