Abstract

This paper deals with a broad investigation on the voltage sag extended-characterization. All types of faults are generated in a scaled network model and a power quality-monitor and a PMU (phasor measurement unit) are used to obtain the voltage sag indices. The sag indices are also obtained through time-domain fault simulations using PSCAD/EMTDC. The measurement results are compared with the fault simulation. Several load conditions are tested. The analysis provides an overview of how accurate the voltage sag extended characterization is when applying the usual simulation tools. Moreover, the results of the measurements obtained by the power quality-monitor and the PMU are compared
