Abstract

The invention discloses a power transmission line area fault positioning method and device based on patrol and maintenance data. The method comprises the steps: obtaining a map and monitoring data of a power transmission line area, dividing a power transmission line into road sections and nodes, wherein the monitoring data includes meteorological monitoring data, power transmission and transformation monitoring data and fault monitoring data; predicting a fault occurrence probability of each road section or node; constructing a to-be-patrolled and maintained display map, wherein the to-be-patrolled and maintained display map includes pre-stored equipment information, the fault occurrence probability of each road section or node in the power transmission line, and labeling information of the monitoring data on corresponding positions of the power transmission line area map; and constructing a power transmission line area model, and determining a fault occurrence position according to the model, including a fault position corresponding to the fault labeling information in the labeling information and a power transmission line section or node position of which the fault occurrence probability is higher than a preset safety threshold. The fault condition can be checked at any time through the power transmission line area model, and the fault position is determined for timely maintenance.

Description

technical field [0001] The present application mainly relates to the technical field of inspection and maintenance, in particular to a method and device for regional fault location of transmission lines based on inspection and maintenance data. Background technique [0002] The maintenance of the power grid is of great significance to the construction of the power grid. During the maintenance of the power grid, it is necessary to patrol the transmission line area, check the defects and faults of substations, towers and transmission lines, and repair them in time to ensure the normal operation of the transmission line. [0003] At present, when patrolling and maintaining the transmission line area, the inspectors mainly check the defects and faults of the facilities in the transmission line area on a daily basis. The form of the document is reported to the management personnel, and the management personnel notifies the maintenance personnel to arrive at the location of the fa...
