The volatge regaulation be calculated by calculating the percentage difference between volatge at no load and voltage at full load
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.
What characteristics are you looking for? At full load, a synchronous generator will be spinning at synchronous speed, providing real power (watts), and likely some reactive power (vars), or it may be taking reactive power from the system to help hold the system voltage down under light loading conditions.
you apply dc voltage to slip rings in synchronous generators polarity will make no difference ( other than when it is first applied )
it is used to calculate the voltage regulation of synchronous generator
By definition a synchronous generator must be synchronous. If it is not "locked in" it is not a synchronous generator, but an induction machine.

Because if speed was used, the power system frequency would be changed. A synchronous generator spins at synchronous speeds. Synchronous generators 101: A typical synchronous generator will have a field winding (typically on the rotor, or rotating part) and a stator winding (the stationary part where power is supplied to the power grid). Current is injected into the field winding, turning it into an electromagnet. This field current is controlled by the Automatic Voltage Regulator (AVR). The more current supplied to the field winding, the stronger the electromagnet becomes, and the more power is required from the prime mover (whatever is supplying the power - steam turbine, for example) to keep the generator spinning at synchronous speeds.
I assume by good regulation you mean a minimal voltage drop internal to the generator. Minimizing this will inherently increase the short circuit current, because it requires minimizing the internal impedance of the 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.
It is conducting OC and SC tests on the given three phase alternator and determining the regulation by synchronous impedance method.
