New apparent power and power factor with non-sinusoidal waveforms

The new concept in sc power theory is investigated for three phase systems. It will be shown that there is discrepancy in the definition of reactive and phasor (complex) power in the time and frequency domains when the conventional power theory is considered It will also be shown that the new power theory consistently defines the power quantities in the time and frequency domains. A comparison between the results given by the new method and the other two methods, known as RMS and System or equivalent apparent power will be presented It is shown that the new method does not posses the shortcomings of the conventional methods.
