Analysis of Waveform Distortion During a Voltage Dip: a Preliminary Study

This paper studies the waveform distortion before, during and after a voltage dip using the Sliding DFT. The effect of the magnitude and the point-on-wave (POW) of inception and recovery of the voltage dip on the waveform distortion, the time evolution of the burst of the low-order harmonic components dominant during the transition segments of the event, the instant and the time interval during which the different harmonic components are over a specific threshold are studied using simulated and real voltage dips, in order to provide an instantaneous, in-depth analysis of voltage supply distortion during a voltage dip.
