TL;DR: A new waveform coding technique, based on wavelet transform, for power quality monitoring purposes, that presents a complete adaptive signal processing approach to estimate the fundamental sinusoidal component and separate it from the transient ones in the monitored signal.

TL;DR: In this article, a phase-locked-loop (PLL)-based power system harmonic estimation algorithm is proposed, which uses an analysis filter bank and multirate processing, and the filter bank is composed of bandpass filters.

TL;DR: The main advantage introduced by the proposed HOS technique refers to its capability to detect voltage disturbances and their start and end points in a frame whose length corresponds to, at least, samples or of the fundamental component if a sampling rate equal to Hz is considered.

TL;DR: A novel SVM-based method for power quality event classification based on the subtraction of the fundamental component from the acquired voltage signal is proposed, showing an improved performance followed by a reasonable computational cost.

TL;DR: In this article, the authors outline a number of possible research directions in power quality, and conclude that sufficient important and interesting research challenges and opportunities remain in the power quality area, and that existing power quality standards should not form a barrier against future research; instead research should result in improved standards as well as completely new concepts.
