Two identical three-phase Alternators A and B share equally a load of 10 MVA at 33 KV and 80% lagging power factor. The synchronous reactance of each generator is 4 ohms per phase and the armature resistance is negligible. Alternator A has its field excitation adjusted to carry a25 amperes at lagging power factor. What is the current delivered by Alternator B ?
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.
