Influence of Geomagnetic Disturbances in the Polar Regions on the Reactive Power Transmissions Mode on the Airline
Analytical expressions are obtained for determining reactive power at the beginning and at the
end of an intersystem overhead line, taking into account the parameters of the magnetization
branches of power transformers, which allow one to take into account the intensity of the
influence of geomagnetic disturbances on power transmission modes. It is shown that an
increase in the intensity of geo-induced currents can completely disrupt the transit of reactive
power due to the multiple increase in the magnetization power of power transformers as a
result of one-sided saturation of magnetic systems. A numerical example is given illustrating
the possibility of terminating the transit of reactive power with sufficiently intense geomagnetic
disturbances.
