HARMONIC DISTORTION ASSESSMENT BY AREA BASED APPROACH AT SINGLE PHASING OF AN INDUCTION MOTOR

This paper presents harmonic distortion assessment by area based approach at single phasing of an induction motor. This has been achieved by assessing voltage and current signals using area based approach. Some specific reference signals have been defined, after which, the real power system data are plotted with this reference signal and areas. Formed by the real power system data with the reference signal, the reference signal and areas have been calculated, where the contributions of fundamental waveform and the harmonic components in real and reactive powers are being assessed separately. Single phasing is done on induction machine as well as the total harmonic distortion factors have been calculated afterwards. Moreover, the significant change is observed in harmonic distortion due to single phasing.
