Evaluating the Uncertainty of a Virtual Power Quality Disturbance Generator

Abstract

This paper presents the metrological evaluation of a proposed virtual power quality (PQ) disturbance generator. The calibration and measurement uncertainty estimation procedures for the RMS voltage and frequency of the generator are explained in detail and the obtained results are presented and discussed. The results show that the measurement uncertainty of the PQ disturbance generator for all reference points is satisfactory, making it suitable for generation of PQ signals for research purposes, especially in the development, testing and improvement of PQ event classifiers.

Characterization of Measurements for Smart Grids

“…In this context, measurements are playing an increasingly important role [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. It is essential to monitor continuously not only the usual quantities, such as voltage, current, active power, and reactive power, but also all the parameters related to power quality.…”
