Abstract

Corona discharges that occur on the conductive elements of power lines are serious problems that can lead to failures in the power system. Corona discharge produces ultraviolet (UV) radiation, which can be detected using special UV sensors. One way to automate inspection of the corona discharge is using of autonomous unmanned aerial vehicles (UAVs) equipped with UV sensor. At the same time, the trajectory of the autonomous UAV flight should be built taking into account the spatial and geometric features of the inspected power lines, as well as the requirements for the gathered data. This work describes a new method for autonomous UAV trajectory planning. The trajectory is planned in accordance with the spatial and geometric characteristics of the inspected powerline, peculiarities of the powerline damage type and in accordance with the quality requirements for the gathered data (representativeness, sample size, unification of the gathering procedure). The trajectory planning method and UV image gathering were simulated in Blender software. As a result, by the fully automated data gathering process, we collected a representative dataset of 200 images in UV spectrum for one lattice tower and two simulated discharges with 326 manually segmented corona discharge areas.
