Q3. For the system shown below:
a) Find the fault current for a three phase fault at bus 2 through a fault impedance of Zf = j0.062 pu.
b) Find the currents from the generators (IG1, IG2, IG3).
Q4. The per unit bus impedance matrix of a four-bus network is:
Generators are connected to buses 1 and 2 and their subtransient reactances of j0.2 pu were included in the impedance matrix calculations. Find the fault currents from the generators for a solid three-phase fault on bus 4.
