GIC Time Varying Electric Field Example

PowerWorld Simulator supports binary and text file formats for time and spatially-varying geomagnetic disturbance (GMD) surface electric field inputs. This format allows development of detailed solar storm scenarios based on historic events or 3D earth conductivity models.

  • Sample (B3D binary format) based on June 22, 2015 event [1], over footprint of the U.S. State of Tennessee.
  • Slides describe how to work with the file. (The TN150 sample case and one-line diagram are available here.)
  • The following videos visualize the event on a synthetic power grid (contains no Critical Energy Infrastructure Information):
