Homework Statement
Explain how the synchronous machine stator current can be varied if the load is constant. Justify your answer with phasor diagrams.
2. The attempt at a solution
If load is constant then load angle, the angle between induced e.m.f. and terminal voltage remains the same. Phase angle is the angle between stator current and terminal voltage, so if I change power factor that will alter stator current? But how can power factor be changed if the load is constant? Does this make any sense?
Are these the phasor diagrams that are expected to see?
Thank you for your comments.
