| Abstract | The relationship between the changes in the earth's magnetic field and the induced geoelectric field during a geomagnetic storm is a frequency-dependent transfer function that depends on earth
resistivity at different depths. Taking into account geological variations over the route of transmission circuits has a significant influence on the induced geoelectric fields as well as on the distribution of GIC over a geographically large
network. This paper summarizes and compares the results of both time-domain and steady-state GIC simulations using laterally uniform and piecewise layered-earth models. |
| Summary | (Plain Language Summary, not published)
Space weather refers to the dynamic conditions on the Sun and in the space environment, in particular, in the near-Earth environment, that can affect
critical infrastructure. NRCan operates the Canadian Space Weather Forecast Centre and conducts research into space weather effects on power systems, pipelines, satellites, radio communications and GNSS positioning to help Canadian industry
understand and mitigate the effects of space weather. This paper describes using multiple earth models for the simulation of geomagnetically induced currents that can be a hazard to power systems. |
