Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
In order to improve comprehensive evaluation of power quality to be more objectively and scientifically, based on weighted Principal Component Analysis, a method of Power Quality comprehensive evaluation for power quality. The method improves the traditional principal component analysis, combining PCA with AHP organically. First, use the improved AHP to determine the weights of original indexes; then, instead of the original indicators of the comprehensive principal component index, use the variance contribution rate of the principal component as the principal component weight; finally, use the linear weighted value of the principal components as a comprehensive assessment. Examples shows that the weighted principal component analysis can evaluate power quality simple, rapidly and accurately.
