Power data processing method and system based on big data

The invention relates to an electric power data processing method based on big data, and the method comprises the following steps: S1, obtaining electric power data, and carrying out the preprocessing, including noise removal, missing value completion and smoothing; s2, carrying out wavelet transform on the preprocessed power data, and converting the preprocessed power data into time domain data; s3, classifying the time domain data based on a support vector machine to obtain an initial classification result; s4, adjusting the initial classification result based on a preset rule to obtain a secondary classification result; s5, based on each classification data characteristic, performing consistency analysis on the secondary classification result, and adjusting the secondary classification result according to an analysis result to obtain a final classification result; and S6, based on a final classification result, performing classified storage on the data. According to the invention, the quality of data acqui
