A three phase star connected alternator of 1000 KVA, and 4600 volts, has an armature resistance of 2 ohms per phase and an armature synchronous reactance of 20 ohms per phase. Find the voltage generated at full load per phase if : a) Supplies power to a purely resistive load b) If you feed a load with inductive power factor of 0.85 c) If you feed a load with a capacitive power factor of 0.75 d) If you feed a load with capacitive power factor 0.4
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.
