Consider the one-line diagram of a three-phase power system in Fig. 2. The three-phase load at bus 4 absorbs 50MVA, 0.7 pf lagging at 10.45 kV. The 220 kV and 110 kV lines have reactances of 45 and 602, respectively. The manufacturer data for the components is: G ={80 MVA, 22 kV, X=17%), M ={66 MVA, 10.45 kV, X=18.5%}, T ={50 MVA, 22/220 kV, X=10%} , T ={40 MVA, 220/11 kV, X=6%}, T3 = {40 MVA, 22/110 kV, X=6.4%}, T4 = {40 MVA, 110/11 kV, X=8%}. 1 T 2 T3 5 38 220 kV T2 3 BE TA 6 BE 4 M Load 110 kV Figure 2: One-line diagram for a simple power system. Select a base of 100 MVA and 22 kV on the generator side. Draw a per-unit impedance diagram showing all impedances, loads and sources. }
