description The invention discloses a multi-harmonic source positioning method and system based on joint entropy. The method comprises the steps of obtaining the number of harmonic sources in the system and harmonic voltage of each measurement node; obtaining the harmonic frequency and the estimated value of each harmonic current of each harmonic source through the harmonic voltage and the harmonic state model of each measurement node; based on a joint entropy method, according to the harmonic voltage and the harmonic times of each measurement node in the system and the estimated value of each harmonic current of each harmonic source, constructing a joint entropy matrix between harmonic waves of different times and the harmonic sources; the joint entropy matrixes between all the harmonics of different times and the harmonic source are gathered, and a joint entropy matrix set is obtained; and obtaining a harmonic source positioning result by combining the entropy matrix set, the harmonic frequency, the number of harmonic
