UPS current sharing control method and system and computer storage medium

The invention relates to the technical field of power equipment, in particular to a UPS current sharing control method and system and a computer storage medium, and the UPS current sharing control method comprises the following steps: obtaining fault load data and use load data; acquiring corresponding to-be-selected load data according to the fault load position; obtaining a segmented load value according to the to-be-selected load value and the use load data; obtaining reset load data according to the segmented load value; and generating and sending a corresponding A-phase control signal, a corresponding B-phase control signal and a corresponding B-phase control signal respectively according to the A-phase reset data, the B-phase reset data and the B-phase reset data. According to the invention, the load difference values of the load cabinets loaded on the A, B and C phases of the UPS starting end box and the preset matching difference value are judged, so that the load of the load cabinets loaded on the A,
