The harmonic pollution at the point of common coupling(PCC) in the public grid is the outcome of combined contribution of multiple harmonic sources.For a better division of harmonic contribution
this paper proposes a method to quantify harmonic contributions of multiple harmonic sources based on FastICA.The background harmonics and the harmonic transfer impedance can be estimated accurately by the proposed method based on FastICA.Harmonic contribution of multiple harmonic source is calculated after the estimation of the background harmonics and the harmonic transfer impedance.
