The present disclosure provides a method for acquiring a galloping value of a transmission line, which relates to the technical field of cable galloping monitoring and can improve the accuracy of cable galloping acquisition. The method for obtaining the galloping value includes: dividing the transmission line into several nodes; obtaining the three-dimensional coordinate data of the phase center corresponding to each node in real time, and the three-dimensional coordinate data of the phase center is the three-dimensional coordinate data of the phase center of the satellite antenna; determining the correction value corresponding to each node , the correction value is the correction value between the satellite antenna and the current node; the three-dimensional coordinates of the cable center of the corresponding node are calculated based on the corrected value and the three-dimensional coordinate data of the phase center; the three-dimensional coordinates of the cable center of all nodes are continuously summarized, Get the gallop value of the transmission line. The present disclosure converts the real-time three-dimensional coordinate data of the phase center to the cable center of the transmission line, and obtains the real-time galloping value of the cable center of the transmission line, so as to accurately collect the galloping data of the transmission line.
Description
technical field [0001] The invention relates to the field of galloping monitoring, in particular to a method for acquiring galloping numerical values of power transmission lines. Background technique [0002] During the operation of overhead transmission wires, various disasters will occur due to the action of natural conditions. Therefore, wire galloping is one of the more serious hazards. Conductor galloping is a kind of low-frequency and large-amplitude self-excited vibration of conductors caused by uneven force on the cross-section of the conductor under the action of wind excitation. Under the corresponding atmospheric conditions, conductor galloping often occurs, and due to its large amplitude, swing, and long duration, conductor galloping can easily cause phase-to-phase flashover and damage to hardware, causing line tripping and power failure, or burning conductors, collapse of towers, and breakage of conductors. and other serious accidents, causing heavy economic ...
