Abstract

The invention discloses a method and system for identifying a relationship between a user meter and a meter box, equipment and a storage medium; the method comprises the steps: firstly, calculating voltage correlation based on a Pearson's correlation coefficient algorithm to rapidly and accurately judge the attribution relationship between the user meter and a branch, greatly shortening the calculation time, and reducing the data size of subsequent calculation; and then constructing a multiple linear regression model, and accurately obtaining the phase of the single-phase user meter based on a mean square error calculation result of each model; finally, constructing combination types of relations between all household meters and meter boxes under each branch, numbering the combination types in sequence, calculating to obtain offset loss of each meter box under the combination types, and performing principal component analysis, thereby quickly and accurately identifying the relation between the household meters and the meter boxes under each branch. Besides, the electricity consumption is adopted as analysis data, and the current I, the voltage U and the active power P are adopted, so that the calculation result is not interfered by empty households, and the accuracy of the identification result is further ensured.

Description

technical field [0001] The present invention relates to the technical field of box meter relationship identification, in particular, to a method, system, equipment, and computer-readable storage medium for identifying the relationship between household watches and meter boxes. Background technique [0002] With the rapid development of the power industry and the increasing demand for electricity, the power industry tends to be intelligent, digital, and model-based. In the low-voltage topology, the topology structure is the basis for application functions such as line loss analysis, fault diagnosis, status evaluation, and three-phase balance, and is crucial to improving power supply reliability and service capability. Since the low-voltage power supply network is located at the end of the power grid and directly faces many users, its topology information mainly depends on the design data during the construction of the station area. Manual entry requires a lot of time and manp...
