Study on Wind-induced Vibration Coefficient of Transmission Lines Based on Equivalent Wind-induced Vibration Theory
Based on the equivalent wind-induced vibration theory,this paper discusses the wind-induced vibration coeffi-cient of transmission lines in order to provide theoretical basis and technical support for the wind-induced vibration protec-tion design of transmission lines.Transmission lines are subjected to wind force during operation,which may cause wind-induced vibration and affect the safety and stability of the lines.As an important tool for analyzing wind-induced vibration problems,equivalent wind-induced vibration theory provides an effective method for calculating wind-induced vibration re-sponse of transmission lines by simplifying the wind field model.Firstly,the basic principle and development of equivalent wind-induced vibration theory are reviewed,and the theoretical basis of the research is clarified.Then,the calculation method of wind-induced vibration coefficient of transmission line lines is discussed in detail through theoretical derivation and numerical simulation.The research results show that the adverse effects of wind-induced vibration on transmission lines can be significantly reduced by reasonable selection of line parameters and effective wind-induced vibration protection measures.
