Operation data feature analysis method suitable for judging operation state of power distribution network

The invention discloses an operation data feature analysis method suitable for judging the operation state of a power distribution network. The method comprises the following steps: acquiring to-be-analyzed data under multiple scene dimensions and preprocessing the to-be-analyzed data; performing feature value calculation based on the preprocessed data to obtain feature value data of each scene dimension at different time sections; grouping the feature value data according to a preset feature dimension, generating a plurality of feature value data slices under each time section, and associating different feature value data slices according to an association relationship between the data; combining the characteristic value data slices with the incidence relation to generate characteristic value data blocks; taking the characteristic value data blocks under different time sections as domains of a two-dimensional table, and generating a two-dimensional characteristic value snapshot table; and performing operatio
