Answer / sukant mohanty

in isjand condition the terminal voltage v is not constant, at that time avr maintain terminal v by increasing or decreasing exitation current. But in synchronised condition the terminal v get constant as the grid voltage, at that time the variable remains ICOS(THETA). So avr maintains p.f. at that time.

Answer / k.prakashchandra

After synchronising ,the voltage can be reset to obtain the
desired pf.Or you can change over to auto pf mode,
selecting the desired pf.AVR maintains the set voltage and
APF maitains the set pf
