Answer Posted / pradeep
reactive power is mainly involve in the transmission line.
in transmission line, they have resistance,
inductance,capacitance.. these are all either store the
energy or dissipate the energy. so that we have a some
losses in the transmission line. this losses will reduce the
generating power and finally we get the power less than the
sending power. generally the output of the generating unit
is represent as kva. apparent power=real power + reactive powr..
real power is part of the power which is used by loads and
then reactive power is not a usefull power.by connecting the
shunt capacitor in parallel we easily inject the reactive
power to the line,becoz capacitor having a leading current
which minimize the lagging current produced by inductance.
reactive power is also called as imaginary power which is
not used for else..
