The invention discloses a method and
system for correcting the topological relation between a distribution network area
transformer and a line, and relates to the technical field of distribution network
transformer topology correction, and the method comprises the steps: obtaining a to-be-corrected area
transformer in a target area, and injecting a target current
signal with a preset frequency and amplitude at a preset side of the area transformer; based on a feeder
terminal unit, acquiring first current signals of a plurality of section switches of the target area; extracting a high-frequency component amplitude of the first current
signal, and obtaining a first
signal amplitude of the section switch based on the high-frequency component amplitude; if the first signal amplitude is greater than a preset threshold value, obtaining a
target line of the section switch; and correcting the
topological graph of the target area based on the
target line, thereby solving the problems of high cost caused by the fact that a monitoring device needs to be additionally arranged on a transformer node in a current
correction method for the topological relation between the power distribution network line and the transformer area, and complexity and difficulty in compatibility caused by the fact that different threshold values and parameters need to be set in an
online algorithm.
