Power grid data type labeling method and device

The invention discloses a power grid data type labeling method and device, and the method comprises the steps: collecting data of different subsystems in a to-be-labeled power grid system, carrying out the format recognition of each piece of data, carrying out the format conversion of the data through a data format standardization rule, obtaining a plurality of pieces of data in a standard format, constructing a dynamic data model, and carrying out the labeling of the types of the data. Cleaning and verifying the data in each standard format according to the dynamic data model to obtain valid data, performing data coding conversion on the valid data to obtain numeric data, preprocessing the numeric data, performing dimension reduction processing on the numeric data to obtain a feature set, and performing feature extraction according to the feature set to obtain a feature extraction result; and training the neural network model by using a cross validation method to obtain an evaluation model, performing data p
