The invention provides a power transmission line windage yaw monitoring method based on dynamic wind and a power transmission line windage yaw monitoring device thereof. The method comprises the steps that the account data and the micrometeorological data of a power transmission line are acquired, wherein the micrometeorological data include average wind speed information; dynamic wind speed data are generated according to the average wind speed information and a dynamic wind speed simulation model; windage yaw angle simulation data are generated according to the dynamic wind speed data, the account data and a windage yaw angle calculation model; and the windage yaw monitoring result of the power transmission line is generated according to the windage yaw angle simulation data. The power transmission line simulation windage yaw angle based on dynamic wind is calculated by acquiring the corresponding information by using the dynamic wind speed simulation model and the windage yaw angle calculation model, windage yaw angle alarm information and treatment suggestions are given, and the dynamic wind information of the power transmission line and online monitoring information on the line tower are fully applied so that the windage yaw accident can be prevented, and the safe operation of the power transmission line can be ensured.
Description
technical field [0001] The invention relates to the field of power transmission lines, in particular to a dynamic wind-based wind deviation monitoring method and device for power transmission lines. Background technique [0002] In recent years, with the rapid growth of UHV transmission lines, the situation of power grid transmission has become increasingly severe. Wind deflection of transmission lines is a very threatening and complicated subject to the safe operation of transmission lines. Wind deflection is a conductor swinging phenomenon caused by wind. The formation of wind deflection generally depends on two factors, namely wind excitation and line structure and parameters. Due to the large range of wind deflection of the transmission line, it may cause phase-to-phase flashover and damage to metal fixtures, or cause serious accidents such as the distance between the conductor and the hill or the house becomes smaller and discharges, the line trips and the power is cut...
