This paper presents a new technique for identifying the locations of multiple harmonic sources in a distribution system using independent component analysis and mutual information theory. Independent component analysis is applied for estimating the current profile of injected harmonic currents caused by the harmonic sources, while the mutual information theory is for estimating the location of harmonic sources. To verify the accuracy of the proposed method, numerical simulations were made in locating multiple harmonic sources in the IEEE 34 bus radial distribution system. Results showed that the proposed method can accurately estimate the locations of multiple harmonic sources without prior knowledge of the network parameters.
