Abstract:
Disclosed are systems and methods to determine an overexcitation condition on electric power delivery system equipment that includes a magnetizing core. Overexcitation conditions are determined even during sub-synchronous resonance, ferro-resonance, and other complex events. Power system voltage is integrated and normalized to determine a flux on the magnetizing core. The flux is compared with a protection model to determine the overexcitation condition on the magnetizing core. Once an overexcitation condition is detected, a protective action may be taken to remove power from the effected power delivery system equipment.

Claim (Index 1):
A device for protecting an electric power delivery system that includes equipment with a magnetizing core, the device comprising:\n a sensor component in electrical communication with a potential transformer of the electric power delivery system, the sensor component including a voltage signal output for providing a voltage signal corresponding with a voltage of the electric power delivery system; a processor; a computer-readable storage medium in communication with the processor and the sensor component, comprising:\n electrical system parameters; \n a protection model; \n flux instructions that when executed by the processor, cause the device to:\n determine whether the electric power system is operating in steady state using the voltage signal from the sensor component; and \n upon determination of a steady state, integrate the voltage signal to produce a flux value; and \n \n protective action instructions that when executed by the processor, cause the device to:\n compare the flux value to a protection model; \n \n determine an overexcitation condition of the magnetizing core based on the comparison of the flux value to the protection model; and,\n upon determination of the overexcitation condition, effect a protective action of the electric power delivery system.
