Line loss analysis method and system based on correlation analysis

The invention discloses a correlation analysis-based line loss analysis method and system, and the method comprises the steps: obtaining historical power data and a line loss abnormal factor list of a target transformer area, carrying out the correlation comparison analysis of the historical power data, obtaining first data, carrying out the clustering analysis of the first data, and obtaining a classification result, according to the line loss abnormal factor list, after the line loss key factor is obtained, the line loss key factor is associated with the classification result to obtain integrated data, and after the integrated data is analyzed and corrected, a correction result is obtained, so that power grid personnel make a regulation and control plan according to the correction result, and the regulation and control plan is used for scheduling the power data. Through a mode of associating multiple groups of power data, different line loss reasons do not need to be independently analyzed for independent r
