Abstract
In order to determine the harmonic contributions at the point of common coupling,a method based on kernel independent component analysis is proposed in this paper. Firstly,the non-Gaussian distribution of observing data is improved after whitening and mean-removal by the kernel principal component analysis.Then,independent component analysis is used in the process of blind source separation of processed data,and harmonic current and harmonic imped⁃ance are thus estimated.Finally,according to the formula of harmonic contributions,the harmonic contributions from harmonic sources are determined.A simulation test on the IEEE 14-node distribution system shows that the proposed method can give more accurate result compared with the independent component analysis .关键词
