ABSTRACT

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 determination 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. A 18 nodes distribution network model is established in MATLAB/simulink to test this method. The results show that this method can quantify harmonic contribution of each harmonic source accurately.
