Promote the application of science and technology to the transmission grid

PTC2 strengthens research and application of science and technology into the company’s production activities, bringing practical efficiency.
Power Transmission Company 2 (PTC2) has strengthened research and applied science and technology to its production activities and has brought practical effects.

Flight equipment application PTC2 uses drones to manage and operate the transmission grid. Assigned by the National Power Transmission Corporation (EVNNPT) to pilot deploy many scientific and technological applications in the management and operation of the transmission grid, since 2017, PTC2 has researched and applied drones in the field of power transmission. management and operation of the transmission grid. The application helps to reduce the level of burden, improve safety and efficiency, and productivity for workers. Mr. Tran Thanh Phong, Director of PTC2 said that in 2019, after being accepted by EVNNPT, PTC2 has synchronously deployed to all affiliated units to deploy the application of flying equipment in the inspection of the power grid and supporting construction supervision and acceptance of power transmission works. From March 2020 up to now, PTC2 has deployed the application of aircraft to periodically check 1,100 km of 220 kV and 500 kV lines with a total flight time of 29,000 minutes. Thereby, it has contributed to reducing the burden, improving safety, efficiency and productivity for workers such as climbing high, contacting electrical equipment with large electromagnetic fields, moving on difficult terrains. difficult access to dangerous plants and animals. Rapid inspection deployment, being able to access locations in areas divided by rainstorms, landslides, real-time recording of the current situation with good quality images, clear viewing angles to help analyze information more accurate assessment and, most importantly, does not require power line interruption. Mr. Tran Thanh Phong analyzed, when applying flying equipment, according to preliminary calculations, on average, to test 1 km of 500 kV transmission line, it takes 0.52 time to perform the traditional method, and 0. 25 workers, down 0.27 jobs (52.38%). In addition, it also saves a lot of time, costs, and other human resources such as: checking thematically on corridors, conductors, lightning conductors, techniques, insulation status, accessories… Along with that, the application of flying equipment to support construction supervision of power transmission works, inspection, supervision and acceptance of pole erection, inspection of conductors, accessories, route corridors, etc. 220 kV, 500 kV works. Not only that, the application of flying equipment helps closely monitor the technical status of the power grid from above and in places where the human eye cannot see (or is very difficult to see). From there, it contributes to reducing the level of burden, improving safety, efficiency and productivity for workers such as climbing high, contacting electrical equipment with large electromagnetic fields, moving on difficult terrains. , access to dangerous plants and animals. Check for dangerous landslide areas or break off during flooding. Efficiency from surveillance camera system thống Camera system to monitor power transmission lines. An effective application for EVNNPT and PTC2 is the installation of line surveillance camera systems. Realizing the high efficiency and applicability of line cameras, PTC2 has installed cameras at all affiliated Power Transmissions since 2020. Up to now, on the PTC2 grid, 31 CCTV cameras have been installed on the transmission lines of the company. The cameras are connected to the company’s dispatching room so that functional departments as well as company leaders can monitor the current status and direct handling remotely when there are abnormalities on the line. According to Mr. Phong, the camera has a wide field of view, so it helps remote observers to easily detect and accurately assess abnormalities arising on the route such as: fires near the corridor, landslides, vehicles passing photos affect the safe operation of the line. Along with that, the camera helps to quickly access the scene to locations in flooded areas, thereby capturing the situation of the route section and directing appropriate handling. Since installing the camera up to now, PTC2 has detected 35 unusual incidents that may affect the safe operation of the line, thereby taking appropriate measures to ensure operation. In the coming time, PTC2 will continue to research on technology solutions for cameras, solutions for data transmission and analysis, image processing, and propose equipment and installation at necessary and important locations for roads. cord.
