Abstract :
An application program that was written on a control center energy management system (EMS) to monitor transformers in a bulk power system for the effect of geomagnetic-induced current (GIC) flows is described. The monitoring program is based on summing the Mvar around a transformer and subtracting from that result the Mvar that theory predicts is being consumed by the transformer. The results of using the program and implementation considerations are discussed.<>
