Considering Load Characteristics Harmonic Penetration in Zhengzhou Converter Station Nearly

This paper presents the rules of harmonic penetration in Zhengzhou harmonic voltage level. National standards limit the harmonic voltage distortion level in the buses, so study the UHV AC/DC hybrid system is significant to power grid. In order to find out the harmonic voltage level near Zhengzhou converter station, a method has been proposed in this paper, including the models of radiation power grid, load characteristics and converter station's AC filter. Finally, according to Zhengzhou converter station power frame sets up a detail model in the simulation software packages PSCAD/EMTDC to study the law of harmonic penetration.
