Frequency Components of Geomagnetically Induced Currents for Power System Modelling
D. T. O. Oyedokun, M. J. Heyns, P. J. Cilliers +1
Geomagnetically induced currents (GICs) in power systems are conventionally modelled as direct currents, based on their commonly described quasi-DC nature. For more representative…
dSECS: Including Variometers in Geomagnetic Field Interpolation
M. J. Heyns, S. I. Lotz, C. T. Gaunt
One of the best tools we have in geophysical modelling is the ability to interpolate the horizontal geomagnetic field at the surface of the Earth. This is especially useful in regi…
Ensemble Estimation of Network Parameters: A Tool to Improve the Real-time Estimation of GICs in the South African Power Network
M. J. Heyns, S. I. Lotz, P. J. Cilliers +1
It has long been known that large grounded conducting networks on the surface of Earth are affected by solar activity and geomagnetic storms. Power networks are such extensive grou…
