reactance’s of the alternator during the periods of the subtransient, transient and steady state periods are following, Leakage reactance(XL)=0.16 ohm, Damper winding reactance(XD)= 0.28 ohm Field winding reactance(Xf)=0.41 ohm and Armature reactance (Xm)= 0.74 ohm. The value of the steady state reactance during the steady state condition is Steady state Reactance Answer
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.
