Title:
RELIABILITY EVALUATION METHOD AND APPARATUS FOR SHARED TOWER BASE STATION POWER SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/027008
Kind Code:
A1
Abstract:
A reliability evaluation method and apparatus for a shared tower base station power supply system. The method comprises: determining whether the power supply mode of a base station power supply system is a direct mains-electricity supply mode; if not, analyzing an external power supply line of the base station power supply system, the voltage of the external power supply line, the average number of faults per month, a fault duration and a remote power supply distance, and determining whether a first-stage DC-DC power supply is installed, to obtain a reliability level; and if yes, analyzing whether a special transformer and an uninterrupted power supply are installed on the base station power supply system, and calculating the residual capacity of a storage battery after a preset operation duration, to obtain a reliability level, so as to determine whether the base station power supply system is reliable. In this way, by analyzing various reliability influence factors of the base station power supply system, the reliability of the base station power supply system is effectively evaluated, and the risk of power failure of the base station power supply system can be accurately analyzed, such that the operation safety of the base station power supply system can be improved, and stable operation of the base station power supply system is guaranteed.
