Industrial load-oriented data missing processing method and device

The invention relates to the technical field of power system loads, in particular to an industrial load-oriented data missing processing method and device. The industrial load-oriented data missing processing method comprises the following steps: acquiring load data and user feature data of each user, and splitting the load data into a plurality of data sets according to the user feature data; carrying out preliminary filling on missing data which can be directly obtained based on the existing load data in the data set; and performing deep filling on the data set which still has missing data after preliminary filling by using a matrix decomposition algorithm. According to the technical scheme, the correlation among various different types of measurement data in the intelligent electric meter is utilized to mine the complex association mode in the data, and the association relationship among different load components at different moments is effectively mined, so that the missing value filling accuracy is impro
