Dear friend answer is in que only.
For 500mw generation you may use 4 nos 125MAV transformer or
2 nos 250MVA transformer.

Answer / umar

Taking power factor = 0.8
so MVA rating for 1 transformer will be =500 / 0.8 = 625 MVA
if three no. of transformers are used then rating of each
transformer will be 208 MVA.
