This paper describes certain functional entity roles and responsibilities related to oscillation detection monitoring, considers how synchrophasor technology may be used to identify actual oscillation events or issues, and describes some of the related commercial applications that are currently...

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...

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.

A white paper by the NASPI Distribution Task Team (January 2018). The purpose of this white paper is to provide an introductory reference for industry and academic practitioners interested in exploring the use of synchrophasors and other time-synchronized measurements for supporting power...

This report is based on the results of the Advanced Electrical Power System Sensors Workshop, held on March 24, 2017 in Gaithersburg, Maryland. The workshop was co-sponsored by the National Institute of Standards and Technology (NIST), and the U.S. Department of Energy (DOE).

Compliance with the NERC requirements for Critical Infrastructure Protection (CIP) for synchrophasor systems in the Version 5 paradigm seems to be a matter of some uncertainty for those in the synchrophasor user community. In the words of the Edison Electric Institute, an organization that...
