Athree-phase, Y-connected, synchronous generator supplies a rated load of 12 MW at a power factor of 0.8 lagging. The synchronous impedance is 0.2 + j2 Ω/phase. If the terminal (line) voltage is 11 kV, calculate the no load line voltage. What is the voltage regulation? Vline(no load)=Eline=13 kV VR(%)=18.19
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.
