Description

technical field [0001] The invention relates to the technical field of power optical cable safety detection, in particular to a real-time monitoring and protection system for power optical cables based on deep learning. Background technique [0002] The smart grid requires the power system to realize the informatization, automation and interaction of the power grid, so the emergence of power optical cables solves the problem of efficient transmission of information. Power optical cable refers to all kinds of composite cables and special optical cables that take into account both power transmission and information communication in the power system. It can be roughly divided into 1. Ground wire wound optical cable GWWOP and bundled optical cable ADL, 2. All-dielectric self-supporting optical cable ADSS and metal self-supporting optical cable MASS, 3. Optical fiber composite overhead ground wire OPGW and optical fiber composite overhead phase wire OPPC, 4. Optical hybrid cable...

AI Technical Summary

Problems solved by technology

The operating environment of the power optical cable varies from overhead to buried, and the environment is relatively complex. The optical fiber inside the power optical cable is more susceptible to failure due to external factors

The traditional power optical cable operation and maintenance work is regular inspection, and when a fault occurs, OTDR (Optical Time Domain Reflectometer) and other equipment are used for positioning and maintenance. It is impossible to predict the occurrence of accidents, and due to the influence of line sag, There is a large discrepancy between the accident distance and the actual geographical location, which brings great difficulty to the timely maintenance of power optical cables
