Abstract

The invention relates to a galloping data mining method and system. The method comprises the following steps of screening a galloping information record table based on a potential galloping influencefactor of a transmission line to obtain a first type of influence factor; sorting the influence factors of the first type of influence factors based on the correlation coefficient corresponding to thefirst type of influence factors and a support vector machine model constructed in advance, and selecting the influence factors satisfying the preset conditions from the sorted first type of influencefactors as the second type of influence factors; and taking the transmission line related data corresponding to the second type influence factor in the galloping information recording table as the galloping data of the galloping analysis. The invention can extract the influence factors closely related to the galloping occurrence rate, and improve the accuracy rate of galloping prediction and early warning.

Description

technical field [0001] The invention relates to the field of disaster prevention and mitigation of power transmission lines, in particular to a method and system for mining galloping data. Background technique [0002] Galloping accidents of transmission lines are one of the important forms of disasters that threaten the safe and stable operation of the power grid. Galloping of transmission lines can easily lead to line tripping, broken wires, and loose fittings and bolts. When galloping accidents occur on large-scale transmission lines, it will cause large-scale power outages , Seriously affecting the safe and stable operation of the large power grid. In recent years, with the rapid development of artificial intelligence technology, its application in the field of power grid disaster prevention and mitigation has been deepening. People have introduced artificial intelligence technology into the prediction and early warning of galloping on transmission lines. Prediction and...
