Abstract

The invention provides a power supply system and a power supply control method. The power supply system comprises an uninterrupted power supply, a storage battery and a management and control device of the energy storage. The uninterrupted power supply is respectively connected with the storage battery and a server of a data center. The management and control device of the energy storage is respectively connected with the uninterrupted power supply and the storage battery and is used to determine a current corresponding power supply phase of a mains supply and controls the charging and discharging of the storage battery according to the current corresponding power supply phase of the mains supply. The technical scheme of the invention can make full use of the storage battery in the power supply system for avoiding the resource waste and can further use the storage battery for supplying the power to a server at a peak stage of the power supply and use the mains power supply for supplying the power to the server and charging the storage battery at the same time at a bottom stage of power supply, when the mains supply is normal, thus achieving peak-load shifting and saving the electricity cost.

Description

[0001] 【Technical Field】 [0002] The invention relates to the technical field of basic equipment of a data center, in particular to a power supply system and a power supply control method thereof. [0003] 【Background technique】 [0004] With the rapid development of cloud computing business, the scale of data centers is getting larger and larger, and the requirements for power supply reliability are getting higher and higher.
