Two three-generator are parallel at 6.6 kV and delivering 3000 kW at 0.8 pf. The impedance for machine A is 0.5+j10 ohm and for B 0.4+j12 ohm. The excitation of A is adjusted to deliver 150 A at lagging pf. Determine the induced emf of machine A.
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.
