Abstract

The invention relates to a three-phase load commutation determination method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring a low-voltage transformer side historical load current and a commutation switch side historical load current at each moment in a historical time period of a power distribution transformer area; according to the historical load current of the low-voltage transformer side, determining a low-voltage side predicted load current at each moment in a preset time period; according to the historical load current of the commutation switch side, determining a predicted load current of the commutation switch side at each moment in a preset time period; and determining a commutation result according to the low-voltage side predicted load current, the commutation switch side historical load current and a preset three-phase unbalanced load commutation model. The commutation result comprises a commutation switch and commutation logic. By adopting the method, the three-phase load balance degree of the power distribution area can be improved.

Description

technical field [0001] The present application relates to the technical field of smart grid, in particular to a method, device, computer equipment and storage medium for determining phase commutation of three-phase loads. Background technique [0002] With the continuous development of the distribution network, more and more power users in the distribution network show the characteristics of scattered geographical distribution and strong randomness of power consumption. Since most power users are single-phase loads, and a large number of single-phase load power users have unbalanced spatial and temporal distribution, which will lead to varying degrees of unbalanced three-phase loads in most distribution stations. [0003] In the traditional technology, the staff of the power system usually divides multiple power users according to the load capacity of multiple power users and the three-phase load of the distribution station area, and tries to ensure that the single-phase loa...
