Earth Resistivity Model for GIC Calculations
PowerWorld Simulator GIC can automatically incorporate scaling factors for geomagnetic latitude and earth resistivity according to NERC TPL-007-2 – Transmission System Planned Performance for Geomagnetic Disturbance Events (October 2017). The earth resistivity models must be loaded from an auxiliary file.
The following models are available:
- as described in TPL-007-2, Table 3: Geoelectric Field Scaling Factors
- as above, except with 10 regions within Alberta as described in GEOLOGICAL SURVEY OF CANADA OPEN FILE 7906: Space Weather Hazard Assessment for Alberta
The files include scaling factors for both the Benchmark Event and the Supplemental Event.
