Abstract: Dynamic line rating (DLR) exploits the dependence of overhead-conductor ampacity on weather conditions to make better use of transmission capacity. IEEE Std 738 and CIGRE TB 601 define the reference thermal models, but provide equations rather than software, so users must implement and verify them independently. PyPacity is an open-source Python library implementing the steady-state and transient methods of both standards behind a common interface, validated against their benchmark cases. Ampacity calculations can be embedded in larger workflows driven by measured or forecast weather data, from single-point studies to long time series.
