answered by Saqib Hayat
The power produce is maximum when the power angle(torque angle) is 90, because P=VE(a)sin(theta)/X(s).

Where,

P is the power per phase.

V is the phase voltage.

E(a) is the internal generated voltage.

Sin(theta) is the angle between rotor feild and stator feild.

X(s) is the synchronous reactance of the machine.
