Abstract

This application discloses a transmission line area fault location method and device based on inspection data. The method includes: acquiring a map and monitoring data of the transmission line area, and the monitoring data includes meteorological monitoring data, power transmission and transformation monitoring data, and fault monitoring Data, divide the transmission line into sections and nodes, and predict the failure probability of each section or node; build a display map to be patrolled, including pre-stored equipment information, failure probability of each section or node in the transmission line, and monitoring data in the transmission Label information on the corresponding position of the line area map; build a transmission line area model, determine the location of the fault according to the model, including the fault location corresponding to the fault label information in the label information, and the transmission line section or section whose failure probability is higher than the preset safety threshold node position. This application can check the fault situation at any time through the regional model of the transmission line, and determine the fault location for timely maintenance.

Description

Technical field [0001] The present application mainly relates to the field of patrol maintenance technology, in particular a transmission line area fault location method and device based on patrol maintenance data. Background [0002] The maintenance of the power grid is of great significance to the construction of the power grid, in the maintenance process of the power grid, the transmission line area should be patrolled and maintained, the defects and faults of the substations, pole towers and transmission lines and other facilities should be checked, and the maintenance should be carried out in time to ensure the normal operation of the transmission line. [0003] At present, when patrolling the transmission line area, the main thing is that the inspectors check the defects and faults of the facilities in the transmission line area on a daily basis, and after the fault is found, the equipment information, fault type and place corresponding to the fault are recorded, and report...
