| Abstract |
Monte Carlo simulation approach for the summation of random harmonic currents arising from six-pulse converters is presented. Converter models for both characteristic and uncharacteristic harmonics are established respectively. The probability characteristics of the harmonics generated by a single converter, with fluctuating loads and unbalanced supply voltage, are first studied. This is followed by simulating the harmonic generation of several independent converters so that the statistical distribution of the resultant harmonic currents can be found. It will be shown that characteristic harmonics and uncharacteristic harmonics possess different probabilistic features because of their different origin. Diversity factor, one of the useful applications of the simulation results, will be derived from the cumulative density function of harmonic resultant. |
