Determine the armature current and power factor of the motor, Electrical Engineering

Assignment Help:

A three-phase, wye-connected, 2300-V, 60-Hz, round-rotor synchronous motor has a syn- chronous reactance of 2 per phase and negligible armature resistance.

(a) If the motor takes a line current of 350 A operating at 0.8 power factor leading, calculate the excitation voltage and the power angle.

(b) If themotor is operating on loadwith a power angle of -20°, and the excitation is adjusted so that the excitation voltage is equal in magnitude to the terminal voltage, determine the armature current and the power factor of the motor.
