Abstract

The wind deflection angle is directly related to the electric gap and the construction cost of the transmission line, so the accuracy of the wind deflection calculation method and the reasonable value of the relevant parameters are very important for the safe operation and economic rationality of the transmission line. In this paper, based on the nonlinear transient analysis method, the characteristics of aerodynamic damping on the transient response of transmission line wind deflection are revealed. At the same time, according to the code of transmission line design in China, the static wind deflection calculation method is used to solve the static wind deflection angle of transmission line, and the dynamic and static calculation models of wind deflection angle are compared.
