Abstract
As a typical Internet of Things (IoT) application of the transmission grid, Unmanned Aerial Vehicle (UAV) is the most feasible solution to replace conventional human maintenance resources during the inspection of power transmission lines. However, limited by the flying range and endurance time, it cannot realize the goal of full-autonomous inspection proposed by the State Grid. Based on the UAV inspection technology and the emerging UAV hangar, a new idea of using smart hangar as a connection point to realize full-autonomous inspection of UAV is proposed in this paper. And then making full use of the smart hangar to solve the battery capacity problem existing in the process of autonomous inspection of UAV. Finally, according to the inspection requirements of transmission towers, the fixed-wing UAV is used for long-distance inspection, and the path planning mathematical model considering the risk probabilities of towers and objective functions is established. Simulation results show that the scheme proposed in this paper can effectively solve the existed problems of UAV inspection.
Highlights
With the sustained and rapid development of the national economy, higher and higher requirements for the power industry have been put forward
The planning of transmission line inspection routes are mainly based on manual or vehicle inspection. [15] established an inspection path planning model for transmission lines based on the vehicle routing problem (VRP)
Based on the above research, this paper proposes a new idea of using smart hangar as a connection point to realize autonomous inspection of Unmanned Aerial Vehicle (UAV)
Summary
With the sustained and rapid development of the national economy, higher and higher requirements for the power industry have been put forward. [13] established the path planning mathematical model and objective function according to the task requirements of transmission line corridor inspection and towers inspection, it considered the performance of multi-rotor UAV. According to the requirements of the line corridor monitoring mission, the fixed-wing UAV is used for long distance inspection and the path planning mathematical model and objective function are established. [15] established an inspection path planning model for transmission lines based on the vehicle routing problem (VRP). In order to realize the goal of transition from manual inspection to man-UAV coordination, and to fully-autonomous UAV inspection planned by the State Grid in the three years.
