wo shunt generators, A and B, are to be operated in parallel to supply a common load. Generator A has a no-load voltage of 245 and a voltage of 220 when it delivers a load of 65 amp. Generator B has a no-load voltage of 230 and a voltage of 220 when it delivers the same current as A. Assuming a straight line characteristics for both machines, calculate the following: the line voltage and the total load in kilowatts when generator B is “floating” and the total load delivered by both machines when the line voltage is 225.
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.
