Calculating Method of theDistortions of Harmonic Current andVoltage on PCC Considering Background Harmonics |
| |
Abstract: | It isneeded to calculate the distortions of harmonic current and voltage on PCC which conformor not to the harmonic standards, when designing resonant harmonic filters. This paperpresents a new calculating method of the distortions of harmonic current and voltage onPCC considering background harmonics. The effects of background harmonics on filter'sperformance are discussed. |
