GIC Visualizations with Geographic Data View
PowerWorld Simulator’s geographic data view tool is uniquely suited for creating wide-area visualization of geomagnetic induced current (GIC) flow. In this example, substations are denoted by circles, sized proportionally to the GIC in the neutral. The color denotes whether GIC is flowing into or out of the ground at the substation. This simulation incorporates the NERC Benchmark GMD Event and default assumptions about transformer and substation characteristics. Files used to generate this graphic may be downloaded here.
