Power flow and Short circuit of 220 kV Substation using ETAP

With increasing load requirements day by day, electric utilities have also grown up to meet the load requirements. The load flow gives us information on bus and branch voltages, active and reactive power, as well as losses in transformers, conductors, cables and the entire system of this substation. Short circuit studies are most needed in a power system in order to properly size the devices, so that they are able to handle short circuit currents. This data is also used to evaluate the correct sizing of protection relays and detection equipment. In this paper, we performed a simulation of 220/63/30 kV the high-voltage substation GHAZAOUET ETAP 16.0.0 using the advanced ETAP software, which solves various problems, such as overloading and live to ensure reliable energy.
