Figure shows a sample power system network and Zpus Matrix elements. For a solid three phase fault take place at bus 3. Determine a) Fault current (b) V1,
V2F and V3f (c) Post fault current in lines 1-2 and 1-3.
The line from bus 1-2 impedance =j0.32p.u
The line from bus 2-3 impedance =j0.67p.u
The line from bus 3-1 impedance =j1.06p.u
The Zpus matrix element values are
Zbus Matrix Z13 = 0.1;
Zbus Matrix Z23 =1.11;
Zbus Matrix Z33 =145;
Fault
G2
