Abstract

The invention provides a power line transmission fault detection method and system. The method comprises the following steps: S1, setting a plurality of sampling points in each power transmission line; S2, when the power line operates normally, setting the acquisition operation parameters of each sampling point, and storing the acquisition operation parameters into a database as normal operation samples; S3, simulating a power line fault, setting a collection operation parameter of each sampling point, and storing the collection operation parameters into the database as a fault sample of a corresponding type; and S4, when one power transmission line fails, setting each sampling point to acquire real-time operation parameters, and matching and comparing the real-time operation parameters with normal operation samples and various types of fault samples in the database to judge the fault transmission line and the fault point. According to the invention, when the power transmission line breaks down, quick positioning of the broken-down power transmission line and the fault point is realized, heavy tasks of finding the transmission line by operation and maintenance personnel are avoided, and the fault processing efficiency of the power transmission line is improved.

Description

technical field [0001] The invention belongs to the technical field of power line fault detection, and in particular relates to a power line transmission fault detection method and system. Background technique [0002] With the expansion of the grid scale, the data volume of power transmission lines is increasing, and the transmission faults of power lines are correspondingly increasing. In the face of huge power transmission lines, it is not only necessary to find out the faulty power lines, but also to locate the fault points of the transmission lines, so as to prepare for the next step to solve the faults of the power transmission lines. The existing method is that the operation and maintenance personnel verify one by one based on experience, which takes a long time, has large errors and heavy tasks. How to quickly find out the faulty power line and accurately locate the fault point is an urgent problem to be solved at present. [0003] This is the deficiency of the pri...
