Question

A 80 MVA synchronous generator has Xs = j8Ω. The generator is supplying its
rated power to an infinite bus at a voltage of 33KV and a power factor of 0.9
lagging.
Determine the following:
a) The generator emf (E) and the power angle.
b) The maximum power (Pmax) that the generator can supply and the armature
current (Ia) in this case (i.e. when the power is maximum) and what is the
power factor?

) A 80 MVA synchronous generator has Xs = j8N. The generator is supplying its
rated power to an infinite bus at a voltage of 33KV and a power factor of 0.9
lagging.
Determine the following:
a) The generator emf (E) and the power angle.
b) The maximum power (Pmax) that the generator can supply and the armature
current (Ia) in this case (i.e. when the power is maximum) and what is the
power factor?
