Answer Posted / raman jain
The generating end voltages are solely decided by the MVA
capacity of generator and cost. for example 250MVA
generator the generating voltage is 16.5 kV but when we go
for 500 MW generator it is 21 kV. If you try to make the
voltage level 16.5 kV for 500 MW generator , the size of
the generator becomes very much large abd very difficult to
transport and costly. on the other hand if you try to use
21 kV voltage generation for 250 MW generators the cost
will increase due the insulation level you are providing.
So it optimse by the designer .
