PMU placement and fault elimination in power system using hybrid Iwd-Goat algorithm

Abstract

Power system fault currents are crucial since they determine the system's capacity to survive the failure. The fault currents may be measured in several methods. Phase voltages and phase currents are measured using the Phaor Measurement Unit (PMU). The faults that occur in power systems are more often unsymmetrical, and Line to line-to-ground faults are the ones that happen there the most frequently. In this study, a technique to compute fault currents in a PC and discover fault currents by monitoring the phase currents using PMU has been provided. If the computed fault current is higher than the stated limit, the relay coil is triggered. The outcomes of the simulation demonstrate the output's perfection.
