The Analysis of Meteorological Conditions for Icing on UHV Transmission Lines in Southeast Guizhou in 2018

The Analysis of Meteorological Conditions for Icing on UHV Transmission Lines in Southeast Guizhou in 2018

Using ERA5 reanalysis data of ECMWF and the ultra-high voltage (UHV) transmission line icing observation system to analyze the meteorological conditions of conductor icing in Guizhou from January 24 to 29, 2018, Results show: The weather conditions for this icing event are that the temperature drops...

The meteorological elements that are more relevant to icing are environmental temperature, air pressure, and precipitation. The relationship with wind speed and relative humidity is small.https://www.e3s-conferences.org/articles/e3sconf/pdf/2021/37/e3sconf_icemee2021_01066.pdf
