Two alternators A and B are in parallel and supplying a 600-V,60 Hz bus load consisting of a 270 kVA unity power factor load a group of induction motors totaling 420 kVA at 89.4 percent power factor and a synchronous motor that draws 300kVA at 92.3 percent power factor leading. If the machine A is carrying 60 percent of the total active power load at a power factor of 70.4 percent lagging, determine the active and reactive components supplied by machine 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.
