how to control the generator output voltage?
what r the condition should satisfy for synchronization?

Answer Posted / rvg.msceb

to be very clear, in commercial generator, nobody using
separated excitation system. self excitation is the best
method unless some specific reasons.

For controlling output voltage, a device called AVR,
automatic voltage regulator to be used, and it sense the
output voltage at each instance, and adjusts accordingly.

these are the condition for syncronization.
1.phase sequence of both generators should be same.
2-frequency shuld be same.
3-terminal voltage shuld be same.
4.both generators should have nearly same percentage
impedence.
