three phase 400v (line voltage) 60 hz 6 pole star connected snkron generator per phase .It has 2 ohm synchronous reactor. the armature current of the generator at full load is 64 A with a power factor of 0.95 back. this generator has 2kW rotation loss and 1.6 kW core loss at full load. the excitation current is set to be 400 V when the generator is idle. generator current with 0.95 back power factor at full load A) find the rotating field current of the generator b) find the mechanical speed of the generator c) What is the output voltage
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.
