    Abstract: Under high wind conditions, transmission lines are prone to faults such as collapse, wire breakage, and tripping, which can severely impact their normal operation and safety. In order to grasp the influence of ground-anchored windproof guy wires on the wind resistance performance of the tower line system under strong wind conditions, this study takes the 110 kV grass a line as the engineering background. Utilizing ANSYS software, a model of the tower-conductor-windproof guy wires was established to analyze the wind resistance effectiveness of the windproof guy wires on the tower line system under wind speeds of 32, 38, and 42 m/s. The tower top displacement ratio and main material buckling ratio were employed to evaluate the wind resistance performance of the tower under different wind speeds. The research findings indicate that as wind speed increases, the tower’s main structural materials consistently meet yield strength requirements,the windproof guy wires remain in a safe operational state, and under the extreme wind speed of 42 m/s, the tower top displacement ratio becomes excessively large, necessitating the implementation of appropriate reinforcement measures.
    Key words: wind-induced displacement; tower line system; wind-induced response; windproof guy wire
