Research on the state assessment system based on digital twin technology

With the rapid development of the power system, the operation status of the transmission line poles and towers is directly related to the security and stability of the power grid. The transmission line poles and towers in the alpine and cold regions have been exposed to the harsh natural environment for a long time, and they are vulnerable to natural disasters such as snow, flood and landslides, leading to the deterioration of the health status of the poles and towers. This paper presents a transmission line tower and tower state evaluation system based on digital twin technology, which realizes the real-time monitoring and prediction of the tower and tower status. Through experimental verification, the system can effectively improve the inspection efficiency and reliability of transmission lines, and reduce the possibility of accidents.
