Enhanced power grid operations with a wide-area synchrophasor measurement & communication network

The recent growth in the synchrophasor measurement and communications technology has been an unprecedented change from an Energy Management System (EMS) control center perspective. For decades, traditional EMS capabilities have been based on 2-4 second SCADA measurements. As the number of milli-second rate, time-tagged synchrophasor Phasor Measurement Units (PMUs) grow in number, control centers now have the ability to monitor in greater in-depth the dynamic behavior of the grid; this leads to more advanced analysis capabilities to help monitor and control the grid to ensure enhanced grid reliability and security.
