Power supply system for data center and control method thereof

Abstract

The invention provides a power supply system for a data center and a control method thereof. The power supply system for the data center comprises first standby power supply equipment, second standby power supply equipment, a first distribution unit, a second distribution unit, battery equipment and a switching unit, wherein the first distribution unit is connected with one end of the first standby power supply equipment, and the second distribution unit is connected with one end of the second standby power supply equipment; the other end of the first standby power supply equipment and the other end of the second standby power supply equipment are both connected to the battery equipment; and the switching unit is arranged between the other end of the first standby power supply equipment and the battery equipment and between the other end of the second standby power supply equipment and the battery equipment. According to the power supply system for the data center and the control method thereof, battery sharing is achieved, the situation that the number of standby single-side fault batteries is reduced is avoided, single-path fault tail end electric equipment in a multi-path redundant system does not sense faults, simple seamless switching is achieved by adopting direct current on a battery side, and power supply of the tail end equipment is not interrupted.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a data center power supply system and a control method thereof. Background technique [0002] In the data center 2N (that is, the uninterruptible power supply (UPS, Uninterruptible Power System) adopts 2+1 parallel redundancy) or multi-channel redundant power supply system, if a single channel fails, the terminal equipment will experience partial UPS interruption or no battery Protection until the system is restored. During this process, the UPS and power supply of the data center's electrical equipment lose redundancy, and the reliability of power supply decreases. In the 2N or multi-channel redundant power supply system of the data center, the battery is configured independently according to the system. If a single-channel system is interrupted, the battery of the system will be withdrawn, and the number of batteries guaranteed by the electrical equipment will be reduced. ...
