Predicting geomagnetic disturbances of power systems

Authors


Abstract

In March, 1989, a severe geomagnetic storm affected power systems in North America and Scandinavia. The most serious consequence was that the six million people of Quebec lost power for nine hours. To predict whether such problems will recur, one must draw on knowledge about the origins of the solar wind and its interaction with the magnetosphere, electromagnetic induction in the Earth, power system characteristics, and the statistics of extreme values.
