The single-line diagram of an unloaded power system is shown in Fig. 3.22. Reactance’s of the two sections of the transmission line are shown on the diagram. , The generators and transformers are rated as follows: a) D raw the impedance diagram with all reactance’s marked in per unit and with letters to indicate points correspond ding to the single-line diagram. Choose a base of 50 MV A, 13.8 kV in the circuit of generator 1. (b) Suppose that the system is unloaded and t h at the voltage throughout the system is 1 .0 per unit on bases c hose n in part {. If a three-phase short circuit occursrrom bus C to g round, rind the p phasor value of the short-circuit current (in amperes) if each genera tor is represented by its sub transient reactance. (c) Find the mega volt-amperes supplied by e ach generator under the conditions of part ( b ).
