Synchronous generators are the majority source of commercial electrical energy. They are commonly used to convert the mechanical power output of steam turbines, gas turbines, reciprocating engines and hydro turbines into electrical power for the grid.
(OR)
A "synchronous" generator runs at a constant speed and draws its excitation from a power source external or independent of the load or transmission network it is supplying. A synchronous generator has an exciter that enables the synchronous generator to produce its own " reactive" power and to also regulate its voltage. Synchronous generators can operate in parallel with the utility or in "stand-alone" or "island" mode. Synchronous generators require a speed reduction gear
By definition a synchronous generator must be synchronous. If it is not "locked in" it is not a synchronous generator, but an induction machine.
synchronous generator
mainly alternator,synchronous motor comes under the synchronous machine.a synchronous motor is not a self starting motor.if a synchronous motor moves with more than synchronous speed then it acts as a synchronous generator.
The governor of the synchronous generator is the device that controls the torque of the rotor, and thus the frequency of the generated alternating current. This is important if the power plant is directly coupled to a transmission system.
synchronous generator is similar to the principle of laws of electro magnetic induction that is "whenever the magnetic flux linking in a conductor that time emf is induced at the ends of the conductor "

ASYNCHRONOUS is a mode whereby events happens irregardless of control. SYNCHRONOUS are this same events but controlled by a timing and/or control
Starting of the synchronous motor using the DC generator creates a magnetic field.
Induction type alternator and synchronous generator.

we do not use induction generator because it require an external source (synchronous generator) that provide reactive power to it.
it is used to calculate the voltage regulation of synchronous generator
when generator works as a motor then the cuurrent path is reversd.
