In most of the studies of electromagnetic effects performed for EMC purposes, the main approach is to study the local effects on equipment, systems or even a single building. It is not usual that analytic methods try to consider the impacts on a large extended network such as a national high voltage power grid. This paper describes such an approach that has successfully modeled several large power grids in Europe, North America and Asia with respect to their response to the very low-frequency transients (time scale of seconds to minutes) due to the threat of geomagnetic storms. This paper will describe the basic modeling accomplished and the validation of the models to geomagnetic storms. |
