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 at200MVA at 13.2kV is supplying a load at rated voltage and load of 100MVA at a power factor of 1 via a 13.2kV(Delta)/220kV(Wye) transformer (voltages are line-line, winding configuration is Delta-Wye) with an equivalent transformer reactance of 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 (S=P+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)
