Abstract

The invention is applicable to the technical field of uninterruptible power supply, and provides a charge and discharge control method, a charge and discharge control device and a UPS. Applied to each of at least two UPSs sharing the same battery pack in a parallel system, the charging and discharging control method includes: obtaining a carrier synchronization signal, and synchronously adjusting the initial carrier signal of its own inverter module based on the carrier synchronization signal , to obtain the synchronous carrier signal of its own inverter module; based on the synchronous carrier signal of its own inverter module, the initial carrier signal of its own charging and discharging module is synchronously adjusted to obtain the synchronous carrier signal of its own charging and discharging module; based on the synchronization of its own charging and discharging module The carrier signal controls the charging and discharging of its own charging and discharging module. The invention can realize the synchronous control of charge and discharge of the UPS sharing the battery pack in the parallel system, and is beneficial to ensure the stable operation of the parallel system.

Description

technical field [0001] The invention belongs to the technical field of uninterruptible power supplies, and in particular relates to a charge and discharge control method, a charge and discharge control device, a UPS and a computer-readable storage medium. Background technique [0002] In some application scenarios of Uninterruptible Power Supply (UPS), in order to maximize the performance of the battery pack and improve the utilization rate of the battery pack, a solution of two or more UPSs sharing the same battery pack is often adopted. [0003] However, in this application scenario, since two or more UPSs sharing the same battery pack need to control the charge and discharge of the shared battery pack, high-frequency components will be generated during the charge and discharge control action. In this way, When two or more UPSs perform charge and discharge control actions separately, the high-frequency components generated by each may superimpose on each other, which not o...
