Research On Energy Saving Technology In Communication Base Station Power Supply System

With the needs of communication technology acting skills and social development,the number of communication base stations has been increasing year by year,especially in the face of the upcoming 5G construction,and the number of base stations will increase explosively.The traditional base station construction model not only wastes the limited resources of the country,but also brings certain pollution to the society.The purpose of green communication is to achieve the negative impact of the communications industry on the environment and minimize the consumption of resources,emphasizing the integration of environmental awareness and the rational use of energy in all aspects of the communications industry.In this paper,the key technologies in green communication base station system are summarized,and combined with the situation of a base station in turpan,the peak filling control strategy based on new energy power generation control and the utilization of cascade batteries is designed.The intelligent management of various kinds of cascade batteries and the main charge and discharge control of lithium batteries can prolong the service life of batteries.In addition,the high temperature in the computer room will cause damage to the battery.Airconditioning is needed to reduce the temperature of the computer room,but this will consume a lot of electricity,thus introducing battery burial and intelligent ventilation technology.The specific work has the following five aspects:(1)Using new energy power generation technology,it can still be used normally in the case of power outages,failure of base station switching power supply cabinets,and damage of lines.For some remote areas,the city can not supply electricity,can use new energy technology to power the base station,to achieve the purpose of continuous work of the base station.In the normal situation of external power supply of the base station,photovoltaic can be connected to the grid to generate electricity,which improves the adaptability and stability of the traditional base station.(2)According to the use of electricity in the city,the use of peak filling technology,the use of batteries to power the base station during the peak period of electricity use,the use of electricity during the low period of electricity use,and the charging of batteries.Through the use of electric equipment such as air conditioning to achieve load translation,battery storage at night low price market power and in the daytime market price when the way to achieve peak filling Valley,effectively reduce the base station electricity cost.(3)In the use of cascading cells,each cell monomer in the battery is monitored and balanced in real time through high-precision detection circuits;It is necessary to use neural network to estimate the health condition and fault condition of battery directly.The residual capacity of the battery was estimated by time-integral method.Different types of echelon batteries are used.(4)The high temperature will harm the life of the battery.The cooling of the air conditioner throughout the day will consume a lot of electricity,and it will also increase the burden of electricity use.Adopt battery burial technology to prolong the service life of batteries;Intelligent outdoor ventilation into the indoor,can effectively use the natural cold source,shorten the operation time of air-conditioning,thereby saving air-conditioning power consumption.(5)The key technologies studied are integrated into a complete green communication base station system and applied in actual base stations,and it is determined through inspection that the key technologies studied in this paper have achieved good results in energy conservation,emission reduction and battery optimization.It has laid a good foundation for the construction of green base station.
