A 500 kVa 3 phase wye connected 2400V line to line alternator has a leakage reactance of 1.5 ohm/phase and an armature resistance of 0.6ohm/phase. The synchronus reactance is six times the leakage reactance. Determine the voltage regulation at 3/4load 0.85 pf. lag and 2400V.
Synchronous Generator
In comparison to an asynchronous generator, it is a machine where the rotor speed is equal to the rotating magnetic field produced by the stator, i.e., mechanical speed is equal to the electrical speed, thus called synchronous, and not asynchronous.
Salient Pole Rotor
Salient pole rotor includes a large number of exposed poles mounted on a magnetic wheel. The construction of a bright pole is as shown in the image on the left. The proposed poles are made of metal laminations. The rotor winding is provided on these poles and is supported by pole shoes.
