Question
Open circuit tests carried out on a 3.5 MVA, 4.16 kV, 60 Hz, three phase star connected synchronous generator gave the following results:
If (A):1015202530
EL (kV):3.54.165.76.257.95
In the short circuit test a field current of 20A was needed to circulate full load current. The armature winding resistance is 1.2Ω /phase, the field winding resistance is 500 Ω and the rotational loss is 250kW. Determine the power angle, the voltage regulation and the efficiency when the generator delivers rated load at terminal voltage of 4.4 kV and at 0.8 power factor leading.
Draw the power flow diagram for the generator and include all values of power flows.
