Answer / kunal

by varying the voltage
as per V/f ratio

Answer / sss

frequeny of a transmission line is varied by changing the synchronous speed of the generator.....which is affected by the equation syn.speed=(120f)/p...so the frequency of the transmission line is varied by changing the poles of the generator...........
however the frequency cannot be maintained as a constant one throughout....it has a slight variation of +/- ...but if there is huge variation the power station tries to decrease/increase the load there by maintaining the frequency as a constant one
