The meteorological parameters along the overhead line change significantly, which have an effect on the surrounding electromagnetic environment. The analysis method of meteorological parameters impacting the electromagnetic environment is presented in this paper. Firstly, the conductor temperature is solved iteratively by the heat balance equation. Secondly, the power flow model involving the conductor temperature is established based on the relationship between line parameters and conductor temperature. Finally, the electromagnetic environment surrounding the line is analyzed based on the changes of line voltage and current. In the case study, the electromagnetic environment of the IEEE 5-bus system under the three cases is analyzed and compared. It is proved that the changes of meteorological parameters along the line have an important impact on the surrounding electromagnetic environment. The calculation of electromagnetic environment considering the changes of meteorological parameters is more accurate.
