Answer / s.karthik

because of the very fact that load on a system seldom
remains constant,when demand increases speed of the
alternator decreases and hence the frequency changes.

Answer / satendra

when the demand is more on grid and generation is less frequency get decreased and vise - vers.
so in order to maintain this near to 50hz grid gave a schedule to power generating station of 15-15 min. for 24 hour's in advance ( prediction on the basis of previous records )
