Dynamic line rating based of metrological parameters and line parameters using IEEE 738-2012

This dataset includes hourly weather data collected from January 1, 2020, to June 30, 2021, along with the dynamic line rating (DLR) of the Trang-Thap Cham 220 kV transmission line in Vietnam. Spanning 18 months, it contains 13,128 data points. The recorded weather parameters include ambient temperature, wind speed, wind direction, and global horizontal irradiance (GHI). The DLR values are calculated based on the IEEE 738-2012 standard, using both meteorological conditions and line parameters.
