Abstract

Abstract

Due to the perennial windy environment， the transmission lines in Tibet frequently experience accidents such as wind-induced flashovers and even tower collapse. Based on a 220 kV transmission line project in Tibet， a study of wind-induced vibration response and the corresponding structural design of a cup-type transmission tower-line system was carried out. Firstly， a method for analyzing wind-induced vibration analysis method was proposed to accurately simulate the dynamic behavior of the transmission tower-line system. The Davenport wind power spectrum and the AR model were employed to simulate the 3D fluctuating wind load， which was then applied to the finite element model of the transmission tower-line system. By combined these methods， dynamic response and wind-induced vibration coefficients of the transmission tower system were calculated on the basis of random vibration theory. Secondly， based on the above methods， simulation calculations were conducted on the cup-type transmission tower and its typical lines in Tibet. The study investigated the vibration response and wind-induced vibration coefficients of the tower-line system under different wind directions. A comparative analysis with current design codes reveals that the existing specifications lead to unreasonable outcomes in the wind-resistant design of transmission towers： the overall design is overly conservative， certain aspects remain unsafe， indicating an urgent need for improvement.
