摘要
Abstract: An analysis is performed of the effect geomagnetic pulsations with frequencies of several millihertz (the Pi3/Pc5 range) have on the magnitude of geomagnetically induced currents (GICs) in the Severnyi Tranzit Electric Power Transmission Line (EPL) located at auroral latitudes. It is shown the characteristics of GICs depend not only on the amplitude of geomagnetic pulsations, but on their polarization, frequency, and spatial scale as well. The correlation between GICs and large-scale geomagnetic disturbances is higher than between GICs and small-scale disturbances. An integral (frequency-averaged) parameter is proposed that determines the correlation between the spectral power of GICs and geomagnetic pulsations. The parameter is tested on a quasi-meridional EPL. © 2021, Allerton Press, Inc.
