Virtualization of Synchronized Phasor Measurement Units Within Real-Time Simulators for Smart Grid Applications
Synchronized Phasor Measurement Units (PMUs) provide GPS-time tagged high-sampling rate positive-sequence voltage and current phasors. When placed in high-voltage substations in power networks, PMUs can provide real-time information that is necessary for the development of Smart Transmission Grid software applications for improving power system monitoring, control and protection. The development of these applications, particularly for use within control centers for on-line purposes, is limited by the availability of and access to real-time PMU data and other information. One attractive approach for application development is the use of real-time simulators to which PMUs can be interfaced as Hardware-In-the-Loop (HIL) devices to harvest PMU data.
