Description

technical field [0001] The invention relates to the technical field of galloping detection of transmission lines, in particular to a system and control method for galloping of transmission lines based on Beidou. Background technique [0002] In the power transmission line, when the conductor is subjected to the lateral velocity wind load, an upward and downward acceleration motion will be generated, which will cause the conductor to be subjected to an aerodynamic moment and thus generate torsion. Wire galloping occurs when the frequency of torsional motion is synchronized with that of its vertical motion. Conductor galloping is a low-frequency (0.1~3HZ), large-amplitude (>10m) vibration phenomenon, and the galloping wave is a standing wave. When galloping, the overhead wires of all gears vibrate in a large wave-like manner, and also have swings. Wire galloping is an important factor that threatens the safe operation of power grids. In addition to causing electrical faul...

AI Technical Summary

Problems solved by technology

Existing transmission line galloping can only be detected manually at designated points on a regular basis. Due to the large number of detection points and the wide distribution of detection points, most of which are distributed in barren mountains and mountains, the detection efficiency is low and the detection cost is high.
