Categorizing PMUs
Description
Phasor measurement units (PMUs) are becoming prevalent on the power system, as is their integration into advanced power system applications. Performance characteristics for the PMU devices are formalized under IEEE Standard C37.118.1-2011 [1]. Formalizing the data requirements for PMU-based...

CRSTT Use Case
Description
An ATC Operations Engineer was using synchrophasor data to review fault operations and stumbled across the odd voltage signature shown below from a PMU monitoring one of our 69 Kv substations. One of the three voltage phases would “drift” away from the other two phase voltages and then eventually...

Event Analysis
CRSTT Use Case
Description
We have observed significant sustained voltage oscillations on the ATC transmission system that were not visible in our SCADA data. These oscillations are normally in the 0.6 – 0.75 Hz range and are lightly damped. They can persist for weeks and then disappear for weeks and even months.

Time Synchronization
Description
NASPI's Time Synchronization Task Force's Technical Report (NASPI-2017-TR-001). The power system uses precision timing for grid monitoring and situational awareness, to coordinate the operation and integration of a variety of grid assets, and for grid protection and operation. Because power systems...
