A 3-phase, 50 Hz, star-connected 4-pole, cylindrical rotor synchronous generator delivers 2.7 MW three phase real power to an electrical grid at 13.5 kV line-to-line
A 3-phase, 50 Hz, star-connected 4-pole, cylindrical rotor synchronous generator delivers 2.7 MW three phase real power to an electrical grid at 13.5 kV line-to-line voltage. A three-phase, 50 Hz, star-connected four-pole cylindrical rotor synchronous generator provides 2.7 MW of three-phase actual power to the grid at a wireline voltage of 13.5 kV. The generator excitationvoltage is at 8.9 kV per-phase and the generator synchronous reactance is 10 per-phase. The excitation voltage of the generator is 8.9 kV/phase, and the synchronous reactance of the generator is 10 / phase. New operating condition: The generator field excitation voltage is reduced from 8.9 kV to7.5 kV per phase. New working condition: the generator excitation voltage per phase is reduced from 8.9kV to 7.5kV. Calculate the generator line current for this new operating condition [A]: Calculation of motor line current under new working conditions [A]
