Time domain simulation of geomagnetically induced current (GIC) flowing in 500‐kV power grid in Japan including a three‐dimensional ground inhomogeneity
We performed 3‐D time domain simulation of geomagnetically induced currents (GICs)
flowing in the Japanese 500‐kV power grid. The three‐dimensional distribution of the
geomagnetically induced electric field (GIE) was calculated by using the finite difference
time domain method with a three‐dimensional electrical conductivity model constructed from
a global relief model and a global map of sediment thickness. First, we imposed a uniform
sheet current at 100‐km altitude with a sinusoidal perturbation to illuminate the influence of …
