Fault detection method and system for overhead distribution lines

Abstract

The invention discloses a fault detection method and system for an overhead power distribution line, which relates to detection technology. To solve the problem of low real-time detection of overhead distribution line faults in the prior art. Including: fault detector, used to detect the operating parameters of the line, determine the fault state of the line according to the operating parameters, and send the operating parameters to the sub-station when the line is detected to be faulty; the sub-station is used to receive the three-phase line Fault detection is performed according to the operating parameters reported by the fault detection sub on the three-phase line, and when a fault occurs on the three-phase line is detected, the fault status and the fault message are sent to the master station ; The main station is used to determine the location of the fault according to the fault status and fault message reported by the sub-station, combined with the topology of the overhead power distribution line, and display the fault location and fault status. The technical solutions provided by the embodiments of the present invention can be applied to overhead power distribution lines.

Description

technical field [0001] The invention relates to detection technology, in particular to a fault detection method and system for overhead power distribution lines. Background technique [0002] The overhead distribution lines start from the substation and lead to various power consumption places, generally distributed in a tree shape, including: trunk lines, branch lines and sub-branch lines on the branch lines, until finally delivered to the distribution transformer. [0003] In the prior art, technical personnel are required to manually detect the fault condition of the overhead power distribution line, so that the real-time performance of fault detection is poor. Contents of the invention [0004] In order to solve the above technical problems, embodiments of the present invention provide a fault detection method and system for overhead power distribution lines, capable of real-time detection of faults in overhead power distribution lines. [0005] A fault detection syst...
