About FNET/GridEye

Operated by the Power Information Technology Laboratory at the University of Tennessee, FNET/GridEye is a low-cost, quickly deployable GPS-synchronized wide-area frequency measurement network. High dynamic accuracy Frequency Disturbance Recorders (FDRs) are used to measure the frequency, phase angle, and voltage of the power system at ordinary 120 V outlets. The measurement data are continuously transmitted via the Internet to the FNET/GridEye servers hosted at the University of Tennessee and Virginia Tech. The Power IT Lab has developed several applications which use the FNET/GridEye data to study the power system, including:

Event detection and location

Oscillation detection

Animations of frequency and angle perturbations

Integration of renewables into the power grid

Detection of system breakup or islanding

Providing grid control input signals

Prediction of grid instability and reduction of blackouts

FNET/GridEye Consortium

The FNET/GridEye Industry Consortium was formed to pool resources to support FNET/GridEye operations and research. Among other benefits, Consortium member companies have access to automatic power grid event alert e-mails. This e-mail includes event size (MW) and location information whenever possible, as well as event data plots. Members also have access to the FNET/GridEye event website, which documents the most recent major events.
