Method, system and device for controlling power supply for supplying power to server in centralized way

Abstract

The invention provides a method, system and device for controlling a power supply for supplying power to a server in a centralized way. The method comprises the following steps of: acquiring the current output current and the current output voltage; calculating actual power consumption of the power supply; calculating the current efficiency of the power supply according to the actual power consumption of the power supply, the number of power supply adjusting modules which are started, the number of input phases and rated power consumption of each power supply adjusting module; and if the current efficiency of the power supply is lower than the first adjusting threshold or is higher than the second adjusting threshold, correspondingly increasing or reducing the number of the power supply adjusting modules which are started and correspond to each input phase. According to the invention, the actual number of the power supply adjusting modules which are started is adjusted, and the power supply adjusting modules can always work at a high-effect region, thus high conversion efficiency is achieved, the aim of improving the conversion efficiency is achieved, and the efficiency for supplying power to the server in the centralized way can be beneficially improved.

Description

technical field [0001] The invention relates to the field of electronic equipment manufacturing, in particular to a method, system and device for controlling centralized power supply of servers. Background technique [0002] With the continuous improvement of Internet service functions, the number of servers in the computer room is also increasing sharply. Since the solution of providing independent power supply for each server will cause a huge waste of resources, the centralized power supply method is currently used to supply power to the servers. However, in the current centralized discharge method, all power adjustment modules are uniformly controlled, that is, they are turned on or off at the same time, and they are kept working. [0003] The disadvantage of the prior art is that because the conversion efficiency of the power adjustment module changes with the load of the server, the current solution cannot ensure that the power adjustment module works in a high-efficie...

Problems solved by technology

[0003] The disadvantage of the existing technology is that because the conversion efficiency of the power adjustment module changes with the load of the server, the current solution cannot ensure that the power adjustment module works in a high-efficiency area, so that high-efficiency effects cannot be achieved

For the N+N dual power supply scheme, the actual load of the power supply is always below 50% of the rated load, and the efficiency of the AC to DC conversion of the power adjustment module is always at a low level, so the energy consumption is relatively high. Not conducive to energy saving
