Power flow and Short circuit of a Real Eectrolysis Plant

This This paper presents a power flow and voltage profile analysis of an electrolysis plant power system with a power supply of 30 MW and a distribution level of 63 kV / 20 kV/ 5.5 kV / 0.4 kV and a 5 MVA steam turbine at the 5.5 kV level. The purpose of the simulation is to predict the behavior of a real system of an HV customer through the power flow and the short circuit with different load and contingency scenarios in order to know and to control its operation, the simulation is carried out using Electrical Transient Analyzer Program (ETAP). The effectiveness of results are proven by comparison to hand calculation and real measures taken in electrolysis plant.
