Abstract—With the advent of Phasor Measurement Units (PMUs), it has become quite possible to monitor and control power system networks in real time. PMUs are able to provide time stamped measurements of voltage and current phasors using Global Positioning System (GPS) satellites, in microseconds. Different phasor estimation techniques such as Fast Fourier transform (FFT), Discrete Fourier transform (DFT) may be used by PMUs to estimate phasors. In this paper, MATLAB and LABVIEW models of PMU have been developed to estimate phasors. Proposed models consider use of DFT using non-recursive as well as recursive algorithms. MATLAB based model has been shown to take less time compared to LABVIEW based model.
