Automatic data labeling method and device based on multi-source power data

The invention relates to the technical field of power grid data management, and discloses an automatic data labeling method and device based on multi-source power data. The method comprises the following steps: acquiring multi-source electric power data from a plurality of data sources, and carrying out data preprocessing on the multi-source electric power data to obtain to-be-labeled data; automatically annotating the to-be-annotated data by utilizing a preset first rule engine to obtain a first annotation result; performing error analysis on the first labeling result according to a preset evaluation standard to obtain an error analysis result; updating the first rule engine into a second rule engine according to the error analysis result; performing quality detection on the first labeling result by utilizing a quality detection algorithm to obtain problem data in the first labeling result; and correcting and labeling problem data in the first labeling result by utilizing a second rule engine to obtain a fin
