Improvement of Accuracy of Power System Spectral Analysis by Coherent Resampling
D. Borkowski,A. Bień +1 more
TL;DR: The coherent resampling (CR) algorithm, which improves the accuracy of discrete Fourier transform (DFT)-based power system frequency analysis, is described in the paper and results obtained are compared to those obtained by other methods.

New method for noninvasive measurement of utility harmonic impedance
D. Borkowski,A. Wetula,A. Bień +2 more
- 22 Jul 2012
TL;DR: In this article, a non-invasive method of measurement for power system harmonic impedance is presented based on the observation of variations of voltage and current harmonics caused by natural load variability.

A new method for noninvasive measurement of grid harmonic impedance with data selection
TL;DR: In this paper, a non-invasive method for the measurement of power grid harmonic impedance is presented, which is based on input-output coherence estimates, which immunizes it against background voltage variations.

Estimation of power system parameters based on load variance observations - laboratory studies
A. Bień,D. Borkowski,A. Wetula +2 more
- 01 Oct 2007
TL;DR: In this article, the authors present new techniques, which may significantly improve accuracy of non-invasive power system identification, such as voltage and current coherent resampling algorithm, which ensures that sampling frequency match actual fundamental frequency of power system, so the DFT analysis is almost leakage-free; envelope detection algorithm which allows to estimate equivalent impedance of the load and its variability for fundamental frequency.
