Modeling of Phasor Measurement Unit (PMU) in Matlab

Abstract

With the arrival of PMUs, controlling and monitoring of energy transmission in real-time has become possible. Time-stamped measurements of voltage and current phasors are provided by the PMUs, in microseconds. Fast Fourier transform (FFT), Discrete Fourier transform (DFT) are phasor estimation techniques which can be used by PMUs to estimate phasors. In this paper, MATLAB/Simulink based models of PMU which uses DFT, have been developed to estimate phasors. There is different algorithm use for updating the phasor also discussed in this paper.
