Phasor Diagram Of Induction Generator. C it is connected to 3 phase ac supply on stator side and to dc on rotor side. B it has a very small air gap as expected inaplain induction motor.
Stator cu loss 3i r 1 2 1 electrical power airgap power 3i r s. For this the induction generator current i s is subtracted vectorially from i l subtracting vectorially means reversing i s and adding it with i l. In this phasor diagram we are going to use.
Since the power factor is 𝜑 lagging the armature current 𝐼 𝑎 lags behind the voltage v by an angle equal to the power factor angle 𝜑 and the direction of the armature current phasor is along ob where ob ia.
Since the power factor is 𝜑 lagging the armature current 𝐼 𝑎 lags behind the voltage v by an angle equal to the power factor angle 𝜑 and the direction of the armature current phasor is along ob where ob ia. Phasor diagram of induction generator. E f which denotes excitation voltage. V ph terminal voltage per phase.
