Question 3 The generator in the Fig. 2 is delivering 1.0 pu active power under pre-fault conditions to the infinite bus. A three-phase fault is occurred at point P, the fault is cleared by opening the two circuit breakers of faulted line. Calculate: E 1.2 Xa=0.25 H=5 losso 10.15 38 10.15 a) The initial load angle. b) The maximum power during fault. c) The new steady state angle. 10.3 10.15 Fig. 2 P 10.15 of 10.15 380 10.15 V = 120⁰
