Phase-splitting identification method and device for electric energy meter in transformer area, terminal and storage medium

Abstract

The invention provides a phase-splitting identification method and device for an electric energy meter in a transformer area, a terminal and a storage medium. The method comprises the steps of obtaining first power consumption and second power consumption in the transformer area through metering equipment in the transformer area, and in combination with a phase-splitting correlation coefficient of the electric energy meter and a fixed loss rate of a line segment, establishing a phase-splitting energy relation model based on an energy conservation law, and resolving the phase-splitting energy relation model through a least square estimation solution algorithm according to a linear algebraic theory, so as to determine a phase line hung on a single-phase user electric energy meter according to an electric energy meter phase-splitting correlation coefficient obtained through model resolving. The technical problems that the manual synchronization efficiency of the existing low-voltage transformer area electric energy meter phase line is low, and the increasingly refined management requirement is difficult to meet are solved.

Description

Technical field [0001] The present application relates to the field of management technology of distribution netwell, and more particularly to a device, apparatus, terminal, and storage medium in an area. Background technique [0002] With the deep development of the quality of power supply quality, the continuous development of power system information processing technology, the standards of power distribution quality and electricity management are currently in the focus of promotion. Currently, resident single-phase electric energy tables typically hooks from different phase lines (A, B, C) on the three-phase supply station area. Accurate determination of the phase line where the electric meter is located, and the power supply customer management of the grid, the phase-phase low voltage line loss calculation, the three-phase load balance adjustment, and the safety and economic operation of the bezel transformer are important. [0003] At present, the power supply department dep...
