The invention provides a harmonic wave responsibility division method based on a multi-harmonic wave source data correlation angle, and the method specifically comprises the steps: obtaining all feeder lines connected to a common connection point of a power grid, collecting a harmonic wave current value and a harmonic wave voltage value of each feeder line, and a harmonic wave voltage value and a phase angle of the common connection point of the power grid, and obtaining a harmonic wave responsibility division result; and carrying out data screening and standardization processing, calculating the correlation degree of each harmonic of each feeder line and the corresponding order harmonic of the harmonic voltage of the common connection point of the power grid, and determining the harmonic responsibility corresponding to each harmonic of each feeder line according to the correlation degree of each harmonic of each feeder line and the corresponding order harmonic of the harmonic voltage of the common connection
