Effects of interactions between stations on the calculation of geomagnetically induced currents in an electric power transmission system
“Geomagnetically induced currents” (GIC) in ground-based technological networks are a manifestation of space weather. GIC are a potential source of problems to the systems and therefore important in practice. GIC in a power system (or in principle in any other discretely-earthed system) can be calculated conveniently by using matrix equations presented earlier. Since temporal variations associa...
متن کاملInfluences of various magnetospheric and ionospheric current systems on 1 geomagnetically induced currents around the world
14 Ground-based observations of geomagnetic field (B-field) are usually a superposition of 15 signatures from different source current systems in the magnetosphere and ionosphere. 16 Fluctuating B-fields generate geoelectric fields (E-fields), which drive geomagnetically induced 17 currents (GIC) in technological conducting media at Earth’s surface. We introduce a new Fourier 18 integral B-fiel...
متن کاملDetermination of ground conductivity and system parameters for optimal modeling of geomagnetically induced current flow in technological systems
In this work, methods to determine technological system parameters and the ground conductivity structure from different sets of geomagnetically induced current (GIC), magnetic field and geoelectric field observations are explored. The goal of the work is to enable optimal modeling of induced currents in any technological system experiencing GIC. As an additional product, the introduced methods ...
متن کاملHigh‐latitude geomagnetically induced current events observed on very low frequency radio wave receiver systems
[1] Noise burst events observed at Sodankylä, Finland, in the frequency range 20–25 kHz during January–April 2005 last up to 4 s, occur more often at midnight, are associated with high geomagnetic activity, and exhibit a quasi‐constant amplitude perturbation ∼15 dB above the background noise levels. We considered the possibility that the events could be caused by lightning noise breakthrough. T...

reduce the moisture content of the pulp coming out of the presses. This will be done by obtaining, from the models, ratios to run the presses at and running the presses at those ratios. Results will be obtained during the next sugar processing campaign at the end of this year. Data analysis, making use of graphic tool XVGR available on X-terminals, will enable to asses the optimisation system e...
