System and method for geomagnetic disturbance determination for power systems

Abstract

A system and method for geomagnetic disturbance determination for a power system, the method including: receiving sensor data including an electric field experienced by one or more portions of the power system; determining a total Geomagnetically Induced Current (GIC) as a multi-variable function of phasors in two field directions proportional to the experienced electric field; determining one or more maximum magnitudes of the total GIC and a corresponding direction; and outputting the determined one or more maximum GIC magnitudes and the corresponding directions. In a particular case, determining the one or more maximum magnitudes of the total GIC and the corresponding direction includes setting a gradient of the total GIC to zero to determine one or more extremum points.
