Background
In the transmission line, when the wire is subjected to the action of a transverse velocity wind load, a downward acceleration motion is generated, and the wire is subjected to the action of an aerodynamic moment to generate torsion. Conductor galloping occurs when the frequency of the torsional motion is synchronized with the frequency of its vertical motion. At present, the mechanism of galloping is not completely clear, the measures for preventing galloping are not complete, but the galloping appearance of the power transmission line can be followed according to the law from the galloping repeatability, and the overhead power transmission line tower is a long-span high-rise structure, has soft wire rigidity and large self-vibration period and is very sensitive to the excitation of wind load. Under the action of some external factors, the galloping amplitude of the power transmission line is large, so that interphase flashover is easily caused, the line is tripped and powered off, and the fault under the condition can bring great harm to the safe operation of the power grid.
