Consider a power system as shown in Figure E8. The manufacturers data, the line and load details are indicated in Table E8. Select a common base of 100MVA and 11kV on the generator side, obtain all the reactances in per unit values and draw the reactance diagram. The motor M operates at 60MVA at 0.8 pf leading at a terminal voltage of 10.5kV and the load is 70MVA at 0.6 p.f. lagging, 10.5kV. Transmission lines 1 and 2 have impedances of j35? and j50? respectively. Determine i) the voltage at the generator bus bar 1 . VBus1?=10.942?7.967?kV
