Harmonic detection based on independent component analysis
Jing Li · Power System Protection and Control · 2009
For a long time,harmonic control has been an important part of power quality control and the accurate detection of harmonic is also the basic condition for the correct analysis.This paper views the problem of harmonic detection as blind source separation(BSS).The independent component analysis(ICA) algorithm is applied in this paper,which is widely used in the filed of BSS.In order to apply ICA algorithm correctly,it is necessary to construct proper number of virtue observed channels.The simulation validates that harmonic can be separated effectively with this method in the circumstances of low demand for the real time.
