Design and Analysis of Load Flow and Fault Studies for an Industrial Power Plant

Abstract

In order to assess the steady state performance and dependability of the system, this project uses ETAP (version 19.0.1) software to offer load flow and fault studies of the industrial plant. The substation provides power to the facility (220/33 kV). This bus is connected to two transformers that feed Zone-I with a 25 MVA, 220/33 kV unit, and 60 MVA. A balanced load distribution and steady operation under typical circumstances are confirmed by the load flow simulation results, which show that all bus voltages stay within ±10% of their nominal values. The fault studies mimic single line-to-ground and three-phase faults at different bus locations in order to examine how the system responds to anomalous circumstances. Examined are the ensuing fault currents and bus voltages, especially during the sub-transient phase.
