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

Abstract

Provided are a method, system and device for controlling the centralized power supply to a server, the method comprising: acquiring a currently outputted current and a currently outputted voltage; calculating the 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 activated power supply adjustment modules, the number of input phases and the rated power consumption of each power supply adjustment module; and if the current efficiency of the power supply is lower than a first adjustment threshold or higher than a second adjustment threshold, then correspondingly increasing or reducing the number of the activated power supply adjustment modules corresponding to each phase input. By adjusting the actual number of the activated power supply adjustment modules, the present invention ensures that the power supply adjustment modules always work in a high efficiency range, thus having high conversion efficiency so as to improve the conversion efficiency and improve the efficiency of the centralized power supply to the server.

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
