Two wye connected alternators A and B are running in parallel to supply the following loads at 6.6 KV lines. Load # 1 ; 8000KVA at unity power factor Load # 2 ; 6000KVA at 0.8 lagging power factor Load # 3 ; 5000KVA at 0.707 lagging power factor If alternator A is adjusted to carry an armature current of 750 amperes at 0.84 lagging power factor. Calculate the armature current and the power factor of 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.
