Data center power supply method and structure

Abstract

The present invention discloses a data center power supply method and structure. The power supply process comprises the steps that: a plurality of power supplies are selected to supply power for a data center; currents supplied by the power supplies are uniformly converted to a direct current which is used to supply to the data center by employing; an energy storage battery is configured at a direct current side after conversion to allow the energy storage battery to have a direct current UPS function, and when a certain power supply has faults, the energy storage battery supplies power to thedata center. Compared to the prior art, the data center power supply method and structure employ double power supplies to supply power at the same time and combine advantages of direct power supply to ensure long-term operation of the system, the energy storage battery is arranged at the direct current side to allow the energy storage battery to have the direct current UPS function to compensatevoltage swell, voltage sag and harmonic interference of a power grid, and therefore, dual-power supply power coordination distribution is achieved, uninterruptible power supply is guaranteed when thedouble power supplies are blacked out, and the data center power supply method and structure are high in practicability, wide in application range and easy to popularize.

Description

technical field [0001] The invention relates to the technical field of data center power supply, in particular to a highly practical data center power supply method and structure. Background technique [0002] In recent years, my country's data center has become an industry. As an important occasion for continuous operation, data centers have very high requirements for power supply reliability and quality. It is of great significance to study high-quality power supply for data centers. [0003] The existing data center power supply scheme is generally equipped with at least 2 AC input power sources - the main power supply grid and a completely independent backup grid or diesel generator; the intermediate link is equipped with a redundant uninterruptible power supply (UPS), and the UPS is generally composed of Composed of rectifiers, inverters, and energy storage batteries, the utility power is transformed by the rectifiers and inverters and then transmitted to the data cente...

Problems solved by technology

However, the existing data center power supply scheme has many energy conversion processes, and there are two harmonic sources of UPS and load in the system

[0006] At the same time, the backup energy (battery) in the UPS can only supply power to the load through the inverter. The existing power supply scheme needs to be further improved in terms of power supply reliability and power supply quality.
