A MATLAB-based PMU simulator

open access: yes2013 IEEE Power & Energy Society General Meeting, 2013
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.
