* synchronous generator generates the power only at
synchronous speed whereas induction generator generates the
power only at ASYNCHRONOUS SPEED.

* induction generator needs AC supply for it's
excitation,but synchronous generator requires DC supply for
excitation purpose.

Answer / s c budhiraja

Syncronous generator runs at syncronous speed of the
system, where as induction generator runs at a speed which
is different from syncronous speed.

As an example if we remome DC excitation from a syncronous
generator and the generator remains connected to the system
AC voltage& the prime mover(turbine etc)Continues running,
the rotor will get excitation induced from the generator
Stator and the generator will continue running as induction
genrator.

Answer / rakesh

an induction generator is one which needs a continuous
supply from the mains , that is it is not self starting it
needs to be first started as an induction motor and then
the primemover torque be applied in opposite to the
electromagnetic toreque so that the rotor startss moving at
a sped greater than the synchronous speed , while a
synchronous generatore is self starting and requires only
prime mover torque which rotates it in the direction
opposite to electromagneticc torque and it rotates with the
synchronous speed
