When in a large power system if the demand of power is
larger than the generated power the frequency of the power
system drops.(assume the rated frequency is 50Hz and now it
So does this mean the demand is totally supplied with a
lower value of generated power in a lower frequency?
Answer / k.prakashchandra
Demand is always equal to generation at a steady
frequency.When frequency drops the demand/load also drops
automatically.If not, frequency goes on dropping till shut down.
