Wavelet transform (WT) is one of the most useful digital signal processing tools for time-
frequency analysis of power quality disturbances in power systems. This paper presents an …

This paper discusses some of the new requirements in the measurement of harmonic
distortion in modern power supply systems: the measurement of the distortion over the …

High-resistance grounding is implemented in the DC zonal electric distribution system
(DCZEDS) to permit continuity of service during a ground fault. To prevent subsequent …

Although it is well known that Fourier analysis is in reality only accurately applicable to
steady state waveforms, it is a widely used tool to study and monitor time-varying signals …

The main objective of this paper is to present a time-varying harmonic decomposition using
the sliding-window Discrete Fourier Transform including a dyadic downsampling. The …

This paper presents a time-varying harmonic analyzer based on the Sliding Window DFT
implemented on a DSP platform. The harmonic decomposition is carried out using the …
