Abstract

Abstract: The use of UAV inspection of substation equipment can achieve multi-angle, refined and high-efficiency inspection of substation equipment. However, UAV inspection of substation equipment is still at the period of research and pilot application. Research perspectives are presented based on a review of the current state of relevant research. Before large-scale promotion, it is recommended to develop technical specifications and standards for UAV inspection of substation equipment and combineing the advantages of different trajectory planning algorithms to realize the intelligent planning of global static trajectory and local dynamic trajectory. In addition, a sample library of substation equipment defects is build and algorithms such as artificial neural networks is used to promote intelligent diagnosis of hidden defects. In view of the deficiencies in the existing safety distance study, it is recommended to fully consider the special characteristics of the substation environment, and propose a safety distance determination method for UAV operations in substations. The safety distance tests of UAV measurement and control performance under electric field and magnetic field environment are carried out and the safety distance criterion is proposed. In addition, the fast analysis method of safety distance of UAV near heterogeneous electrode/conductor is established by using machine learning and data fitting.

Key words: substation, substation equipment, UAV, inspection, safety distance
