Abstract

The invention relates to the field of meteorological disaster early warning of power systems, especially a power transmission line galloping prediction method and system based on inversion algorithm,and a storage medium. The method and system are used for the fine prediction of galloping caused by icing. The method comprises the steps: carrying out the coarse prediction of the region distributioncondition of the power transmission line galloping according to a galloping prediction calculation model and corresponding input elements; searching a power transmission line pole in a region which is predicted to be a galloping region according to the GIS information of a power grid, and recording the inversion information of the searched power transmission line pole; carrying out the spatial connection of poles correlated with two ends of each power transmission line segment according to the inversion information, and generating a power transmission line with the galloping index, wherein the secondary refining prediction of the galloping index needs to be carried out; carrying out the secondary refining prediction of the galloping index for all element points on the power transmission line based on a meteorological element spatial interpolation method, and carrying out the direct display of a prediction result according to the corresponding relation between a preset galloping indexand a color value.

Description

technical field [0001] The invention relates to the field of early warning of meteorological disasters in power systems, in particular to a method, system and storage medium for galloping prediction of transmission lines based on an inversion algorithm. Background technique [0002] In recent years, with the frequent occurrence of transmission line galloping in winter prone to ice-covered areas, it often causes line tripping, broken wires, loose fittings and bolts, and possible tower collapses, resulting in great harm to the safe operation of the power grid, causing major economic losses and social influences. Considering that the power industry is an industry with high meteorological sensitivity and high demand, once meteorological elements (including temperature, humidity, wind speed and direction, air pressure, precipitation, rain and snow, etc.) change, it may cause icing, dancing, strong wind, etc. Meteorological disasters and secondary disasters threaten the stable op...
