Question: example the single line diagram of a simple three bus...

Question details

Example The single line diagram of a simple three bus power system is shown in Figure. Each generator is represented by an emf behind the transient reactance All impedances are expressed in per unit on a common 100MVA, for simplicity, resistances are neglected. The following assumptions are made j0.1 j0.2 Shunt capacitances are neglected and the system is considered on no load 降 j0.1 j0.8 All generators are running at their rated voltage and rated frequency with their emfs in phase j0.4 j0.4 Determine the fault current, the bus voltages and the line currents during the fault when a balanced three phase fault with a fault impedance Zf-0.16pu occurs on Bus 3 42
