Abstract EN

A new quad bundle conductor galloping model considering wake effect is proposed to solve the problem of different aerodynamic coefficients of each subconductor of iced quad bundle conductor.

Based on the quasistatic theory, a new 3-DOF (three degrees of freedom) galloping model of iced quad bundle conductors is established, which can accurately reflect the energy transfer and galloping of quad bundle conductor in three directions.

After a series of formula derivations, the conductor stability judgment formula is obtained.

In the wind tunnel test, according to the actual engineering situation, different variables are set up to accurately simulate the galloping of iced quad bundle conductor under the wind, and the aerodynamic coefficient is obtained.

Finally, according to the stability judgment formula of this paper, calculate the critical wind speed of conductor galloping through programming.

The dates of wind tunnel test and calculation in this paper can be used in the antigalloping design of transmission lines.
