چکیده انگلیسی:
This paper presents a set ofnew power quantities that aims to assess the harmonic distortion considering low and high order harmonics. The power quantities in the IEEE Standard 1459-2010 are revisited and new formulations are developed after separating the low order (harmonics below 40th order) and high order (harmonics above 40th order) from the fundamental (i.e. 60-Hz) component of the voltage and current. Two distinct groups of new power quantities are introduced in this study namely: (1) low/high order harmonic distortion powers and (2) low/high order harmonic interference powers. The results of the experimental measurement performed on different light bulb types from different manufacturers are presented in this paper to exemplify the usefulness of the developed power quantities. The results of the measurement reveal that the new power quantities can be useful in assessing the harmonic distortion/interference resulting from low/high order harmonics and also can be useful in many detection applications which require extracting prominent features in high frequency range above 2.4 kHz (or 40th harmonic order). Keywords: Distortion power Harmonic analysis Low/high order harmonic Power components Power measurement Power quality Time-frequency analysis
