Q. 75 If the initial accelerating power isX pu, the initial acceleration in elect-deg/sec,and the inertia constant in MJ-sec/elect-deg respectively will be A generator feeds power to an infinite bus through a double circuit transmission line. A 3-phase fault occurs at the middle point of one of the lines. The infinite bus voltage is 1 pu, the transient internal voltage of the generator is 1.1 pu and the equivalent transfer admittance during fault is 0.8 pu. The 100 MVA generator has an inertia constant of 5 MJ/MVA and it was delivering 1.0 pu power prior of the fault with rotor power angle of
. The system frequency is 50 Hz
