Theoretical and Experimental Comparison of Total Harmonic Distortion Factors for the Evaluation of Harmonic and Interharmonic Pollution of Grid-Conne…

2006

Grid connected photovoltaic systems are increasingly used in electrical distribution systems. However, they inject distorted currents. Therefore special attention must be paid to harmonic and interharmonic measurements. The new edition of IEC 61000-4-7 introduces the concept of harmonic and interharmonic groups, which implies new expressions for Total Harmonic Distortion factors. In the paper a theoretical and experimental comparison is made between the different total harmonic distortion factors in order to show which of the currently defined distortion factors is best-suited to detect harmonic and interharmonic pollution. Experimental tests were carried out first by means of a calibrator …
