The Synchrophasor Unit or commonly called Phasor Measurement Unit (PMU) is the essential component in the modern power grid which plays a significant role in monitoring, control and protection of the power system. PMU offers synchronized measurements of voltage, current and frequency on a real-time basis. Therefore, it is necessary to install Phasor Measurement Devices in the power grid, which can provide a complete state of each bus system. In this paper, Non-recursive based Discrete Fourier Transform (DFT) approach is implemented for the modelling of PMU due to its stable nature. The entire work is done using the NI LabVIEW software, and the results obtained from the model are validated with mathematical analysis.
