Power transmission line icing analysis method based on multi-dimensional meteorological factor influence

The invention provides a power transmission line icing analysis method based on multi-dimensional meteorological factor influence, which belongs to the technical field of power system operation and maintenance and comprises a data acquisition and reading module for acquiring multi-dimensional icing meteorological information data; preprocessing the data, screening and eliminating abnormal data, and normalizing to eliminate dimensional difference and proportion difference between different attributes; the data analysis processing module is used for performing correlation analysis on the data in the step S2; the data SVC classification module is used for establishing a support vector machine classification model according to the optimal icing factor combination obtained in the step S3; the accuracy of the analysis model is improved by adopting grey correlation analysis and Pearson combination correlation analysis methods and establishing a support vector machine classification model according to data balance ac
