Research on Quantitative Assessment Method of Transmission Line Maintenance Risk Based on Cloud Modeling

Aiming at the problem of rising safety risks of power grid, equipment and personnel in the operation, maintenance and repair of transmission lines in recent years, a risk assessment strategy for the operation, maintenance and repair of transmission lines based on cloud model is proposed. Firstly, we sorted out 16 key risk factors in the operation and maintenance of super/ultra-high voltage transmission lines, then utilized the entropy weight method to assign weights to the combination of risk factors, and finally realized the risk assessment of the operation and maintenance of transmission lines based on the cloud model.
