Problems solved by technology

Nowadays, the power supply method of data centers mostly adopts AC power supply as the main power supply and configures UPS emergency power supply as emergency backup power supply. This method has many intermediate conversion links, and the power loss is relatively large during the power transmission process. Under the background of the popularization of DC power supply , it is necessary to propose a new power supply control system to better cooperate with the DC transmission system

Embodiment Construction

[0041] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0042] The power supply system of the data center in the prior art includes a UPS power supply scheme and an HVDC power supply scheme, such as figure 2 As shown in a) and b), in the UPS power supply scheme, the AC power is converted to DC through the AC / DC converter module and the DC / DC converter module, and then passed through the DC / DC converter module after uncontrolled rectification and PFC module To supply power to the data center, the HVDC power supply scheme is to convert the AC power to DC through the AC / DC converter module, and then supply power to the data center through the DC / DC converter module after uncontrolled rectification and PFC module. It can be seen that in the prior art, ...

Abstract

The invention relates to a novel AC / DC hybrid data center power supply control system, which comprises a DC power supply, an AC power supply, a renewable energy power generation power supply, a DC power supply bus, an AC power supply bus, a DC / DC converter module, an AC / DC converter module, a storage battery pack, a multi-type AC / DC conversion module and a state monitoring system, wherein any one of an efficient mode, a balanced mode and a renewable energy consumption mode is adopted to supply power to a data center. According to the invention, the DC power supply and the AC power supply simultaneously supply power to the power distribution bus, wherein both DC power supply and AC power supply are provided, so that the power distribution efficiency is improved, and the power supply reliability of the data center is ensured; and a renewable energy power generation power supply is additionally arranged on the DC side, so that the control mode has renewable energy consumption capability.

Description

technical field [0001] The invention belongs to the technical field of power distribution system control, and in particular relates to a novel AC-DC hybrid data center power supply control system, and also relates to a control method of the data center power supply control system. Background technique [0002] The traditional data center adopts the UPS AC power distribution scheme. The power from the AC power supply to the server motherboard has gone through multiple AC-DC conversion links, resulting in large losses and low efficiency. Since 2015, the HVDC power distribution mode has been gradually promoted, which saves the post-inverter link of the UPS power supply, improves efficiency, and has been more and more widely used in the IT industry. However, there are still multiple conversion links in the above method, and the loss is still relatively large. In addition, the communication HVDC power supply cannot be configured with a bypass branch, and the reliability is reduc...
