Question: A three phase generator rated at 2 0 0 MVA at 1 3 . 2 kV is supplying a load at rated voltage and load

A three phase generator rated at 200 MVA at 13.2 kV is supplying a load at rated voltage and load of 100 MVA via a \(13.2\mathrm{kV}(\mathrm{Delta})/220\mathrm{kV}(\mathrm{Wye})\) transformer (voltages are lineline, winding configuration is Delta-Wye) with an equivalent reactance of \(\mathrm{Xeq}=0.5\) Ohms. Neglecting excitation, find:
1. Load Current (Rated load voltage is rating of secondary winding of transformer).(10)
2. Generator Voltage (10)
3. Power generated by the machine (\(\mathrm{S}=\mathrm{P}+\mathrm{jQ}\))(5)
4. Neglect the phase shift in the transformer - do you still get the same voltage magnitude of the generator and power rating of the generator? What does this tell you? (5)
