Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] Such as figure 1 As shown, the distributed UPS power supply system of the bank data center includes a high and low voltage power distribution system, a diesel generator, a two-way computer room power distribution cabinet, multiple cabinets, a battery energy storage device, and a distributed UPS device. One cabinet is connected to a distributed UPS device. and a battery storage device. The high and low voltage power distribution system is connected by two 10kV city power lines. The diesel generator is used as the emergency backup power supply for the high and low voltage power distribution system. The output of the high and low voltage power distribution system is connected to two power distribution cabinets in the machine room, which are distributed UPS device and battery energy storage device for power supply. Distributed UPS device i...

Abstract

The invention discloses a distributed UPS system for a bank data center and a power supply method thereof. The system comprises a plurality of cabinets, a battery energy storage device and dispersed UPS devices, wherein one cabinet is correspondingly connected with one dispersed UPS device and one battery energy storage device, and each dispersed UPS device comprises a system power supply detection control module, a parallel switching device, a power supply output device, an AC / DC rectification device and a DC / AC inversion device. The parallel switching devices are used for switching between the commercial power supply and battery inversion power supply; the output ends of the parallel switching devices are connected with the power output devices, and the output ends of the power output devices supply power to loads in the cabinets; the system power supply detection control modules are used for detecting commercial power and controlling charging of the battery energy storage devices. According to the invention, the system employs the distributed power supply mode, so that the possibility of systematic and large-area power failure accidents is reduced; the field is saved; the systemno-load time is reduced; the air conditioner configuration and power consumption are reduced, and the PUE value of the data center is reduced.

Description

technical field [0001] The invention relates to a power supply system, in particular to a distributed UPS power supply system for a bank data center. Background technique [0002] With the development of bank information technology, bank data center has become an important carrier of its business development. With the continuous acceleration of the construction of bank data center computer rooms, UPS (uninterruptible power supply system) power supply, which is the main power supply method of data centers, has also been widely used. The traditional data center computer room power supply method mostly adopts UPS 2N redundant configuration online power supply, the equipment redundancy is large, and the system undergoes secondary conversion of AC-DC-AC, which directly reduces the conversion efficiency. Medium energy loss and online UPS are always in online working state and energy consumption is unavoidable. [0003] Not only that, communication accidents caused by centralized...
