This paper introduces the use of a fourth-order
frequency-domain statistical estimator, the spectral kurtosis
(SK), in the field of power-quality analysis. The research has
been organized in the frame of a research national project
and points towards the implementation of these techniques
into an automatic platform to perform PQ analysis in power
plants and power inverters. Higher-order statistics in the
frequency domain manage to distinguish 3 types of electrical
anomalies (sags, swells and transients), with an accuracy of
83%.
