Data center with function of utilizing novel energy and low PUE (power usage effectiveness) value

Abstract

The invention particularly relates to a data center with a function of utilizing novel energy and a low PUE (power usage effectiveness) value. The data center with the function of utilizing the novel energy and the low PUE value comprises a commercial power direct supply system, a high-voltage direct-current 240V power supply system and a photovoltaic power supply system. The photovoltaic power supply system is a main power supply system, and the commercial power direct supply system and the high-voltage direct-current 240V power supply system are reserved for standby application. The data center with the function of utilizing the novel energy and the low PUE value has the advantages that power can be generated by the aid of solar energy, accordingly, usage of commercial power can be reduced, the PUE of the data center can be lowered, the operation cost of the data center can be reduced, and energy can be saved; requirements that the data center runs for a long time after the commercial power fails further can be met, accordingly, data can be assuredly normally and stably processed by clients, and severe loss can be prevented.

Description

technical field [0001] The invention relates to the technical field of data center power supply design, in particular to a data center utilizing new energy with a low PUE value. Background technique [0002] At present, most data centers use two lines of mains power to supply power to IT equipment after passing through UPS. After one line of mains power is cut off, the other line of mains power must be able to fully bear the power supply for all loads. This requires that the capacity of the UPS must be at least equal to the total capacity of all compliances at the time of design. Considering redundancy factors, the capacity of the UPS generally selected is several times the design load capacity. When the two UPSs are working, the load of each It will not exceed 50% of the design capacity. Under this load condition, the efficiency of the UPS is relatively low, resulting in a great waste of energy. [0003] At present, the feasibility of 240V high-voltage DC technology has be...

Problems solved by technology

[0004] However, if the two mains are powered off, the data center will stop working, which cannot guarantee the long-term stable operation of the data center.

In order to solve this problem, some data centers use generators to generate electricity, which can ensure the stable operation of the data center, but this has certain flaws for green data centers, which will cause certain pollution to the environment and do not meet the needs of energy saving.
