Modeling & Mitigation of Geomagnetically Induced Currents (GICs) for Single-Phase Power Transformer

2018 International Conference on Computer, Control, Electrical, and Electronics Engineering (ICCCEEE), 2018
This paper describes the effect of Geomagnetically Induced Currents (GICs) in single phase-transformer and how to mitigation the phenomena using capacitor at the ground for the transformer, Geomagnetically Induced Currents (GICs) arise from fluctuations in Earth’s magnetic field and can reach alarmingly high levels and cause malfunctions or blackouts ...

Laboratory validation of the relationship between Geomagnetically Induced Current (GIC) and transformer absorbed reactive power

2011 IEEE Electrical Power and Energy Conference, 2011
This paper presents the theory and simulation work to establish a relationship between Geomagnetically Induced Current (GIC) flowing through a transformer's windings and the reactive power absorbed by that transformer's core. This relationship is determined in laboratory for various levels of GICs injected under different loading conditions of a ...

Evaluation of the Risk of Geomagnetic Induced Currents (GIC's) in Power Transformers of the National Electrical System

2018 XXXI INTERNATIONAL SUMMER MEETING ON POWER AND INDUSTRIAL APPLICATIONS (RVP-AI), 2018
Solar activity presents a potential risk of causing damage to different technological sectors such as communications and electrical networks. A total or partial collapse of an electrical network by an extreme solar storm would bring catastrophic consequences to the daily chores of our society.

Averages of geomagnetically induced currents (GIC) in the Finnish 400kV electric power transmission system and the effect of neutral point reactors on GIC

Journal of Atmospheric and Solar-Terrestrial Physics, 2005
Abstract Geomagnetically induced currents (GIC) in technological systems are ground effects of space weather. In electric power transmission networks, GIC may produce problems by saturating transformers. Thus, GIC flowing into and from the Earth through transformers are more important in practice than GIC in transmission lines. In this paper, we show

Investigating the possibility of the development of geomagnetically induced currents (GIC) in Greece

Η εμφάνιση Γεωμαγνητικώς Επαγομένων Ρευμάτων (Geomagnetically Induced Currents – GICs) στην επιφάνεια της Γης σχετίζεται με έντονες διακυμάνσεις του γεωμαγνητικού πεδίου των οποίων η πηγή βρίσκεται σε ισχυρές διαταραχές στο εγγύς γεωδιάστημα. Η ανάπτυξη GICs μπορεί να έχει ως πιθανό αποτέλεσμα την πρόκληση σοβαρών βλαβών στο δίκτυο μεταφοράς και ...
