2. Goal: to visualize FNET data
Background
Goal: to visualize FNET data
FNET is a frequency monitoring system composed of a network of FDRs
FDRs, or Frequency Disturbance Recorders, are small boxes that record frequency values across the grid and report back to FNET
Data visualization allows people to get an intuitive sense of the dynamics of a power system in ways that raw data would never allow
Visualization allows us to easily pinpoint the location of an event
An FDR
FNET

3. For instance

5. FNET Data FDRs provide four important types of data:
Location of the FDR
Frequency of the grid at the FDR’s location
Voltage angle at the FDR’s location
Exact time of frequency and voltage angle readings
This data is critical to the visualization process
This information is recorded in the format of a text file:
North American FDR locations

6. Visualization Import and sort FDR data
Unwrapping and processing angle data
Freq.
Ang.Dev.
Ang.Osc.
“memd” function to isolate oscillations
Interpolate data with griddata function
Load and subtract coastline
Draw 3D contour map using “surf” function
FOR loop to animate

7. Oscillation Case April 27, 2011- large hail storms hit east Tennessee
11 large 500kv lines were taken down by the storm
The storm resulted in extended outages and damage to roofs and cars
