State Grid Pingdingshan Power Supply Company: Deepening the New Operation and Inspection Model to Safeguard the Safety of the Power Grid

“There’s no issue with the route planning for this transmission tower; we can upload the data to the system and start the autonomous inspections once we return.” On November 5th, Song Shaohang, an employee at the Transmission Operation and Inspection Center of the State Grid Pingdingshan Power Supply Company, conducted a field verification of the 110 kV Suzi Line 37# transmission tower route planning A Data. This is an example of the company’s efforts to deepen the application of its new operation and inspection model.

According to reports, the company actively implements strategic deployments from higher authorities, is guided by a modern equipment management system, focuses on building a new operation and inspection model that combines “3D inspections + centralized monitoring,” and expands the application of new equipment and technologies such as drones and visualization, aims to improve inspection efficiency and ensure the safe and stable operation of the power grid. The company continues to deepen the the application of drones for transmission line inspections, it is making targeted efforts in fundamental areas such as drone configuration, training and certification, flight route planning, inspection applications, and infrared detection. Currently, 51 drones have been deployed, and 49 employees have received the AOPA (Aircraft Operator Certificate). The flight route coverage rate for drones in the airworthiness zones of 220 kV transmission lines is 100%, while the coverage rate for 110 kV and above transmission lines is 65.28%. So far, autonomous inspections have been carried out on a total of 2,802 transmission towers. The company has also accelerated the deployment of visual online monitoring devices for transmission lines to improve the coverage and online connectivity of monitoring systems. A total of 847 monitoring devices have been installed, essentially covering key sections of 220 kV transmission lines, and meeting the needs for wide-area monitoring of geological disasters, external threats from debris or objects in transmission corridors, and fire hazards in mountain areas, this has effectively ensured the safety of the power supply in Pingdingshan.

Looking ahead, the State Grid Pingdingshan Power Supply Company will continue to improve the efficiency and quality of drone-based autonomous inspections in local areas, expand the application of new equipment and technologies, and promote the digital transformation of inspection work, all in efforts to safeguard the safe and stable operation of the power grid.
