Application of power theory for electricity metering in presence of distortion

Abstract

Abstract At enterprises, electricity metering devices are used everywhere, which incorporate various formulas for calculating power. The division of power into active, reactive and full is valid only in the case of sinusoidal currents and voltages. In the case of non-sinusoidal waveforms of current and voltage, which are most often found in industrial networks of enterprises, it is necessary to use additional concepts and correct formulas for calculating powers in order to avoid errors. The article compares the methods of calculating the power in the non-sinusoidal mode, which can be used to more correctly record electricity in industrial networks of enterprises.
