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.
Q. A 100-kW, 230-V, dc shunt generator, with R a = 0.05 , and R f = 57.5 has no-load rotational loss (friction, windage, and core loss) of 1.8 kW. Compute: (a) The generato
