• Execute a Simulated Case in ePHASORsim• Data is generated in the form of simulated PMU’s.• Data from simulated PMU’s is sent to ePDC (EPG’s enhanced Phasor Data
Concentrator) using multiple C37.118 streams of data• ePDC synchronizes the data and sends unified C37.118 stream to RTDMS• RTDMS receives the data, calculates, and alarms on
• Power (MW)• System Frequency• Voltage and Angle Sensitivities• Mode Meters• Oscillations• Etc.
• Monitor results in RTDMS 2012 Visualization Client Application
