1.After synchronising the alternator to the grid,how we r
delivering power to the grid?if the i/p increases does the
speed hence frequency increases?
2.y the power factor is changing when exitation changes?what
is the relation with p.f and flux?

If you want to increase the speed more input to prime mover
is required.As the grid is very large ,this will result only
in more sharing of load.You can not change the frequency.If
you increase the excitation, the terminal voltage of gen
will increase ,and you can not increase the entire grid
voltage . This additional voltage will drop in the gen
itself and a small portion of grid ,resulting in more gen
current and increased lagging pf.If the terminal voltage of
the gen is less than grid voltage the power will be
evacuated at leading pf and again more gen current.

I don't understand why when we connect high voltage source in DC to electronic motor , we must add capacitor and resistor in parallel ? (I know that we use capacitor because we want to absorb the current that in the first second electronic motor in opposed with current course produce. ) what are the feature of Resistor and in such situation ?
