The structural health assessment method of transmission tower

As a key part of the transmission line, it is very important to accurately evaluate the actual structural state of the transmission tower in operation for the safe and stable operation of the power system. In this paper, a method for evaluating the health status of transmission tower structures is proposed. Firstly, structural health factors are screened, and then the set pair analysis method is used to deal with the ambiguity and certainty of structural health factors. Subjective and objective factors are combined to obtain the total weight of structural health factors, and then the structural health status of the transmission tower is evaluated. Finally, an example analysis is performed to verify the results. The results show that the structural health assessment method proposed in this paper can accurately evaluate the structural state of the transmission tower.
