Modeling of industrial power distribution circuits for voltage sag and fault analysis
This thesis uses the Electromagnetic Transients Program (EMTP) to simulate sensitive electrical loads during voltage sags. The study begins by discussing the modeling procedure for induction motors based on manufacturer datasheets. It then investigates and develops a 24-pulse variable frequency …

Analyzing voltage sag direction using protective relays and deep-learning methods
… identifying the direction of voltage sags in the distribution circuits. Voltage sags arise from the presence of short-circuit faults involving single, double, and three phase-to-ground conditions. The direction of the fault is based on the direction of power flow before the occurrence of the …
