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...

Embodiment Construction

[0016] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments. It should be noted that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0017] The data center using new energy and low PUE value includes a city power direct supply system, a high voltage DC 240V power supply system and a photovoltaic power supply system, a total of 3 power supply systems, using the photovoltaic power supply system as the main power supply system, and the city power direct supply system Standby with the high-voltage DC 240V power supply system; the photovoltaic power supply system raises the DC voltage by forming a series circuit of solar panels, parallels the raised DC voltage in the collector box, and converts it into 240V high-v...
