A generator feeds power to an infinite bus through a double

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 p u The 100 MVA generator has an inertia constant of 5mJ MVA and it was delivering 1 0 p u power prior of the fault with rotor power angle of 30 The system frequency is 50 Hz If the initial accelerating power is X pu the initial acceleration in elect dag sec and the inertia constant in MJ sec elect deg respectively will be
