Abstract

Ionic wind generated by corona discharging of transmission line, and which generated vortex-induced vibration of the transmission line. In order to study the characteristics of the vibration, studied the field strength of corona and mechanism of ionic, and established the vibration equation of corona vortex-induced vibration. Using Runge-Kutta method to calculate the vibration response of the 220KV cable, researched the impact on amplitude of cable by the air humidity and density, conductor surface conditions, cable structure factors and tensions. Analysis and conclusions in this paper, can be used as references for designing UHV transmission liens, upgrading the existing lines and controlling vibration.
