Abstract
The real time high accuracy measurement of waveform phasors is one of the many open challenges that need to be addressed for monitoring of power grids. In the paper accuracy of Discrete Fourier Transform (DFT) and Taylor Expansion Weighted Least Square (TWLS) phasor estimation techniques are compared using single phase Phasor Measurement Unit (PMU) Simulink model for various static & dynamic conditions. Total vector error is used as an indexed tool to evaluate quality of phasor measurement.
