Power Quality Monitoring using Synchronized Phasor Measurements: An approach based on hardware-in-the-loop simulations

Abstract

In this work, synchronized measurements are used for power system monitoring based on hardware-in-the-loop simulations. A metering equipment with phasor measurement unit function is used to monitor in real time electrical and power quality parameters such as voltage phasors, THD (Total Harmonic Distortion), IHD (Individual Harmonic Distortion), system frequency and voltage sags in a power grid. Simulations are carried out using RTDS (Real Time Digital Simulator) in order to compare simulated values with their corresponding measured ones, with the purpose of investigating the metering equipment performance by hardware-in-the-loop tests.
