Description of the experiment
As shown in the diagram above the variable frequency inverter fed Induction Motor is driving the Generator. Induction motor represents the Turbine in real life situations. The generator is loaded. Induction motor is driven by V/F inverter. This controls the torque provided on the generator shaft. With increasing torque the real power generated goes up. When the field voltage is increased the reactive power generated by the generator goes up but not the real power delivered. Effectively, the increased field current increases the generator voltage behind its reactance while the mains supply maintains its terminal voltage at the system voltage level.
