“…It is however possible to estimate the phase-to-phase rms voltage and the dip type from the three phase-to-neutral rms voltages using the methods described in [22], [24] and [25]. Knowing the three phase-to-phase rms voltages, the phase-toneutral voltages minus zero-sequence can be calculated using basic mathematics.…”

This paper compares different methods for voltagedip characterization. Those methods are based on earlier proposed algorithms for extracting three-phase characteristics (dip type, characteristic voltage, and so-called "PN factor"). The difference between the 12 methods being studied in this paper is in the way in which the time variation of those characteristics is treated to result in single-event characteristics. The methods are applied to 259 measured voltage dips and the performance of the different methods is compared. It is found that small differences in method can result in big difference in results. From the comparison, two methods are selected and recommended for inclusion in international standards.

“…2, to provide the proper control action as function of any specific voltage sag type and depth, accordingly with the LVRT requirements. Some methods are reported [40], [41], which provide detection within 1 ms [42]- [44] after the perturbation appearance. In this work, for the sake of simplicity, this detection has not been implemented, because the voltage dip type and depth is previously known, as it is set by the user both at our experimental setup and the simulations.…”
