Wide-Area Measurement Data Analytics Using Fnet/Grideye: A Review

With the increasing size and complexity of the power grid, wide-area measurement system (WAMS) has been studied and implemented more widely. As a pioneering WAMS deployed at the distribution level, the frequency monitoring network FNET/GridEye has been providing independent observation of dynamic performance of U.S. and other worldwide power grids continuously since 2004. By utilizing GPS-time-synchronized monitors called frequency disturbance recorders (FDRs), FNET/GridEye is capable to capture dynamic grid behaviors (e.g., frequency and voltage phase angle). Compared to the three-phase phasor measurement units (PMUs), the FDRs can be conveniently deployed across the grid at distribution level without complex procedure and heavy outlay. With years' continuous development and systematic management, FNET/GridEye has thrived with multiple advanced online and offline applications. The system has been proved to be highly effective in enhancing power grid operators' situational awareness capabilities. In this paper, the latest accomplishments of FNET/GridEye will be introduced.
