Using PQ-monitor and PMU for voltage sag extended-characterization
Paper i proceeding, 2006

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.
