A MATLAB-based PMU simulator

The use of Phasor Measurement Unit (PMU) data in power system operation is of increasing importance. These data are currently used for real-time operation monitoring and off-line analysis. A good understanding of the phasor measurement process is essential for phasor quality analysis as well as for the design of advanced control and protection schemes. In this paper the main computational algorithms involved in the phasor measurement process are illustrated using a Matlab based PMU simulator.
