A 2200-V, 1000-hp, three-phase, 60-Hz, 16-pole, wye-connected, wound-rotor induction motor is connected to a 2200-V, three-phase, 60-Hz bus that is supplied by synchronous generators. The per-phase equivalent circuit of has the following parameters: R1 = 0.1 = R 2, Xl1 = 0.625 = X l2, and Xm = 20 .Ifthe machine is driven at a speed of 459 r/min to act as a generator of real power, find the rotor current referred to the stator and the real and reactive power outputs of the induction machine.
The superposition theorem states: 'In any network made up of linear resistances and having more than single source of e.m.f, the resultant current flowing in any branch is the
Ac power has significant practical advantages over dc power in generation, transmission, and distribution. One major drawback of the single-phase circuit is the oscillatory nature
