21Generators
Synchronous generators are used in power plants. Its structure is similar to the asynchronous machine. The only difference is the number of synchronous turns, no slippage, and it is dependent on the mains frequency and the number of poles. The operating behavior of the generator is briefly explained for sinusoidal currents and voltages both on the fixed network and in isolated operation.
In contrast to the asynchronous machine, there is no relative movement (slip) between the rotor and stator fields, the stationary influence of the exciter field is compensated by the pole wheel voltage 
expressed. The rotor excited with direct ...
