Тhе method of expanding the autonomy of the unmanned aircraft’s (drone’s) piloting for monitoring the technical condition of power transmission lines with voltage of 6-10 kV

It is remarked that the interest of civil and military organizations to the usage of unmanned aircrafts - drones has increased. The main directions and achievements in the activity of the Department "Electric power supply" of Oryol State Agrarian University devoted to the drone’s adaptation for the needs of the electric power industry in particular for monitoring the technical condition of power transmission lines with the voltage 6-10 kV are consecrated. It is noted that designed experimental model of drone has been successfully tested in production environment, confirming the expected technical and economic effect which is achieved with a significant reduction of the transit time information about damage to power transmission lines and more rapid elimination of emergency situations. By the results of the tests one of the main tasks for the further continuation of the work consists in improving the methods of auto-pilot drone in adverse weather conditions. The specific of operation is studied and the critical review of the complex automated control system of the unmanned aircrafts is presented. The requirements to the newly developed the drone’s hardware part are formulated. The reliability, safety of the remote flying and the providing of the electromagnetic compatibility with power transmission lines with the voltage 6-10 kV are the main of the requirements. The method of the emergency piloting of the drone executing the monitoring the technical condition of power transmission lines with the voltage 6-10 kV is presented. The proposed control method allows to the drone, which lost the radio connection with ground control post, to continue the flying along power transmission line to the predetermined area of the emergency landing. The drone’s control is realized by the emergency automatic pilot with servo drive using the sensitive elements such as capacitive aerial sensor and the inductor reacting to the electromagnetic field with the voltage 6-10 kV as the source of control signals. The presented method is very relevant when the monitoring the technical condition of power transmission lines because allows to promote the flight safety and to prevent the material damage caused by the fall and the loss of the drone.
