Find the power factor?

An overexcited 2300-V, 3-phase, wye-connected synchronous motor runs at a power angle of 21 degrees. The per-phase synchronous impedance is 0.1 + J2 ohm. If the motor takes a line current of 350 A.

  1. Find the power factor
  2. If the internal induced voltage is the same as the line voltage at the power angle 20 degrees, find the power factor and the line current of the motor
  3. In part b) find the developed power of this motor
