Abstract

The invention is applicable to the technical field of uninterruptible power supplies, and provides a control method and a control device of a multi-system uninterruptible power supply, a control terminal and a computer readable storage medium. The control method comprises the following steps of: acquiring the load rate of a multi-system uninterrupted power supply; acquiring a working mode of the multi-system uninterrupted power supply; determining whether the load rate is smaller than a preset first threshold value or not; and if the load rate is smaller than the first threshold value, reducing the operation number of the power units of the multi-system uninterrupted power supply corresponding to the working mode. According to the invention, the operation efficiency of the multi-system uninterrupted power supply under a light load condition can be improved.

Description

technical field [0001] The invention belongs to the technical field of uninterruptible power supplies, and in particular relates to a control method, a control device, a control terminal and a computer-readable storage medium for a multi-system uninterruptible power supply. Background technique [0002] Uninterruptible power supply, that is, UPS (Uninterruptible Power Supply), is a system device that connects the battery to the host, and converts DC power into commercial power through a module circuit such as the host inverter. It is mainly used to provide stable and uninterrupted power supply for loads. When the mains input is normal, the UPS will stabilize the mains and supply it to the load. At this time, the UPS is an AC voltage stabilizer, and it can also charge the battery at the same time; when the mains input is interrupted, the UPS immediately The DC power of the battery is switched and converted through the inverter to continue to supply power to the load, so as t...
