WebAnswer: * Lagging reactive power is prominently absorbed by inductors (induction motors for instance) and this is supplied by alternators at generating stations since induction … WebFirst, we need to calculate the apparent power in kVA. We can do this by multiplying load voltage by load current: As we can see, 2.308 kVA is a much larger figure than 1.5 kW, which tells us that the power factor in this circuit is rather poor (substantially less than 1). Now, we figure the power factor of this load by dividing the true power ... simulink save scope data to workspaceWebMar 28, 2024 · We could over-excite the generator and supply leading reactive power to cancel out lagging reactive power and make power factor 1. But you have done nothing, since the genset still supplies the same apparent power. No gain. Power factor correction is viable, but is costly. It can be done for total or on a load by load basis. rcw false reporting
