Experimental Verification of Active Power Calculation in Nonsinusoidal Single Phase Circuits

Abstract

The active power in nonlinear single-phase circuit is measured by a new speciallydeveloped experimental model. The experiments are carried out for sinusoidal and nonsinusoidal voltage and current waveforms. The results of the experiments show that the total active power is a sum of the active powers produced by the voltage and current harmonics with the same serial number.

Limits in Application of Main Power Theories for Calculation of Active and Apparent Powers in Linear and Non-Linear Circuits and Systems

“…The power converters are chosen as a model because they may behave both as a linear or non-linear element and harmonic spectrum of their input and output are different Thus, the results obtained may be applied to any linear or non-linear circuit and systems under sinusoidal and non-sinusoidal conditions. The analysis is limited by the active power calculations because, to the best of our knowledge, only for this power there is experimental verification of the theoretical results [6].…”
