Complex
power S
(in VA) is the product of rms voltage
phasor and the complex conjugate of the rms current phasor. It is also the
complex sum of real power P and reactive power Q.
The
total complex power in a network is the sum of the complex powers of the
individual components. Total real power and reactive power are also,
respectively, the sums of the individual real power and the reactive powers,
but the total apparent power is not calculated by the process.
