wat is the role of reactive power in power generation?why
we have maintain it.

Answer Posted / kani

The role of reactive power is very important in power
generation as generation revolves around the priciple of
induction.This is the cause for magnetic field by which the
power is gererated.

Reactive power=VI SinQ
If the phase angle between voltage and current is zero then
sinq=0 ,there is no reactive power ,there is no magnetic
field ,there is no power generation
