Abstract

The invention discloses a method, device and system for distributing load. The method comprises the following steps: acquiring parameter information of at least one power supply system, wherein the parameter information includes at least one of the following information: voltage information and current information; outputting a control command according to the parameter information; controlling the on-off state of a load distribution branch according to the control command, and ensuring that the load distribution branch is connected with at least one power supply system and at least one load circuit. By adopting the method, device and system disclosed by the invention, the technical problems that the load access of the power supply systems only can be manually adjusted and the load cannot be automatically distributed in the prior art can be solved.

Description

technical field [0001] The invention relates to the field of electric power supply, in particular to a method, device and system for distributing loads. Background technique [0002] Due to differences in construction time and construction departments, there are multiple sets of uninterruptible power supply systems of different brands and capacities installed in the power room. Although these uninterruptible power supply systems have different brands and different capacities, for electrical equipment, there is only one uninterruptible power supply system for the power supply system, and multiple uninterruptible power supply systems cannot be used in parallel. It can be used independently, and can only be accessed by manually adjusting the load of the uninterruptible power supply system. Existing uninterruptible power supply systems have the following disadvantages: [0003] (1) It is necessary to arrange for multiple sets of equipment to be shut down; [0004] (2) It is n...
