Abstract:

Geomagnetic induced currents are generated on the power system by solar storms and solar flare, which causes damages to power transformer. GIC (DC) current when enter the power grid through the neutral point of transformer causes saturation of the transformer and the transformer gets damaged hence a novel hardware model was fabricated and the effects were analyzed. A software simulation was done using MATLAB and the effects on power transformer were observed to be increase in reactive power consumption and fluctuating harmonics in neutral current and the excitations current. Were analyzed which has got significance in the practical field to give warnings before the occurrence of the damage to the transformer and the subsequent interruption of power supply.
