Abstract：Aiming at the problem of using OTDR(Optical Time - domain Reflectometer) to obtain operation and maintenance change parameters for power communication lines, which is easily affected by signal differences, leading to abnormal response of some operation and maintenance faults, this paper researches on power communication line operation and maintenance method based on decoupling algorithm of temperature and stress data, which is applied to calculate the global temperature field of power operation and maintenance, and a power line operation and maintenance converter is designed to achieve power communication line operation and maintenance. The application results show that the operation and maintenance method of power communication lines based on temperature and stress data decoupling algorithm has a good effect, with a maximum detection and response speed of only 20 seconds for line faults, which can effectively respond to faults, and is reliable and valuable for application, and has made a certain contribution to reducing the operation risk of power communication lines.
