Abstract

This paper investigates the distribution of geomagnetically induced currents in the 750 kV main power grids. In the environment of Matlab/Simulink software was created that allows quickly to perform electrical network equipment on/off switching with visualization of the distribution of geomagnetically induced currents in GoogleEarth. It was shown that the distribution of geomagnetically induced currents in the network depends on the direction of geoelectrical field. According to the simulation results the distribution pattern of maximum currents through the network were obtained and some substations were determined which can be considered potentially vulnerable during geomagnetic storms.
