A naval in-board synchronous generator has anapparent power of 50 kVA and supplies a three-phasenetwork of 380 V. Compute the phase currents, theactive powers, and the reactive powers ifa. The power factor is 0.85.b. The power factor is 1.
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.
