Abstract

This article first introduces the construction of digital models for transmission lines based on point clouds and design data, providing a physical model for numerical simulation. Secondly, based on the online tension value of icing, the calculation of icing thickness is carried out to establish and simulate an icing thickness model for transmission lines in an icing environment. The average relative error method is used to verify that the accuracy of this model is 92.2%. Finally, the simulated icing thickness and real-time meteorological conditions of the transmission line are fed into the state equation to dynamically simulate the sag of the icing transmission line under different icing meteorological conditions. Based on the results of the digital model construction, a digital twin model of icing on the transmission line is constructed. After verification, the maximum average error in space is 0.067m, which enables accurate dynamic simulation of the icing status of the transmission line and reduces losses caused by icing disasters.
