Abstract:Shunt metering technology provides strong support for accurate electricity bill allocation for operators, rapid promotion of site electricity bill lump sums, real-time electricity bill confirmation, and collaborative consumption reduction and efficiency improvement. As the demand for 5G base station construction increases significantly, it is urgent for tower companies to quickly and efficiently promote the installation of branch metering equipment at site sites and achieve accurate, transparent and clear apportionment of operators’ electricity bills. Based on this, analysis and research were conducted from the aspects of branch metering construction background, construction goals, branch metering technical standards, branch metering project construction implementation, etc., and suggestions were put forward for the later installation and construction of branch metering equipment of the Tower Company.

 Acrel Tower Base Station Energy Consumption Solutions

(1) This solution was designed for IoT online precise sub energy monitoring of the overall telecommunications tower base station.

(2) Normally, the power system of base station could be devided into AC part and DC part [-48Vdc]. And usually request a multi-channel metering regarding the different energy usage like for different telecommunications service provider's base station communications equipment [DC side]. Or for either the mains supply, back-up generator, lighting, airconditioner of base station. [AC side] Thus, multi-channel DC or AC energy meter will be the key to solve such request.

(3) This solution was majorly for both cloud&local energy monitoring, different from Acrel local energy monitoring solution which is designed for base station local energy monitoring by providing only hardware. In other hands, this solution could be also adapted to 3rd party IoT energy monitoring system via API or SDK for data transferation
