Abstract:Ice cover on transmission lines may lead to transmission line breakage, flashover, tower collapse and other accidents, which seriously affects the stable operation of the power grid. In order to better grasp the mechanical properties of key components of transmission towers, improve the operation quality of transmission towers, and reduce the operation and maintenance costs of transmission towers, the mechanical simulation interface is designed in this paper for transmission towers with interactive functions based on COMSOL and Matlab. Users can input different simulation parameters by themselves, and click on the nodes of transmission towers of different voltage levels to carry out mechanical simulation and mechanical parameter calculation of key components of transmission towers. The interface can realize the dynamic output of geometric modeling, mesh partitioning, simulation results and mechanical parameters such as maximum node displacement and maximum axial stress of key components of the transmission tower, and evaluate the mechanical failure state of the transmission tower according to the output parameters. The simulation interface is easy to operate, and the user can get the simulation results intuitively, which is conducive to enhancing the user"s understanding of the mechanical simulation of the key components of transmission towers, and it is of great significance for carrying out the operation and maintenance of the key components of transmission towers and improving the operation quality of transmission towers.
