| Abstract: | The structural characteristics of the related power electronic devices， the mechanism of harmonic generation and superposition are analyzed. The reasons of the harmonic injection and user voltage swell are discussed for the power electronic devices in the distribution networks. The simulation model of the harmonic influence is constructed for the voltage of the distribution networks. The actual harmonic content of several power electronic devices is measured on site. Based on the measured data and some examples，including an actual rural low-voltage distribution network and the medium-voltage distribution network of IEEE 33 nodes， the phenomenon of higher household voltage rise is verified by the simulation and comparison of several operation cases， and the measures to treat the voltage swell are proposed. |
