Abstract

Finite element models of three-phase transmission lines with triangle and vertical conductor arrangements are set up, and the anti-galloping efficiency of the interphase spacers mounted on the transmission lines is numerically investigated by means of the ABAQUS software. Galloping responses of the transmission lines in steady wind flow and stochastic wind field are simulated, and the necessity to take the stochastic wind field into account in these analyses is illustrated through the comparison of the dynamic responses of the two transmission lines in the two kinds of wind fields. The anti-galloping efficiency of the inperphase spacers in the transmission line with triangle and vertical conductor arrangements are analyzed based on the numerical simulation results.
