Abstract

The invention is applicable to the technical field of UPS, and provides a control method and device of UPS parallel operation and reverse flow prevention and a terminal. The control method comprises the following steps of: acquiring first information, wherein the first information is used for indicating a current bus voltage of a first UPS; acquiring second information, wherein the second information is used for indicating the current state of an output air switch of the first UPS; and controlling the output mode of a second UPS based on the first information and the second information, wherein the first UPS and the second UPS form the UPS parallel operation. The method can avoid the voltage reverse flow phenomenon in the UPS parallel operation application scene.

Description

technical field [0001] The invention belongs to the technical field of UPS, and in particular relates to a control method, a control device, a terminal and a computer-readable storage medium for UPS parallel machine anti-backfeeding. Background technique [0002] Uninterruptible Power Supply (UPS for short) is a system device that connects an energy storage unit (such as a storage battery) with a host computer and converts DC power into commercial power through the inverter of the host computer. It is mainly used to power a single computer, computer The network system or other electrical equipment such as solenoid valves, pressure transmitters and other loads provide stable and uninterrupted power supply. UPS parallel operation refers to the parallel operation of two UPSs to supply power to the load to provide more reliable power supply. [0003] However, voltage backfeeding may occur between two parallel UPSs. For example, in some scenarios, the output voltage of one UPS (...
