thanks for your quick response.
In my case Steam Turbine rating is 32125 kVA with 0,8 pf.
11/31,5 kV transformer will be used. Alternatives are 35000 kVA ONAN or 25000/35000 kVA, 32000/40000 kVA.
Of course 25000/35000 kVA is the best solution in terms of investment cost. But I coulnt find any...
What is the sizing criteria or standard for selecting kVA rating of a Gas Turbine and Steam Turbine Generator?
Equal kVA rating of Generator and Transformer creates temperature rise problems in some cases as per my previous experiance.
