Line Anti icing
Inverse DLR: minimum-current calculations that keep conductors above the ice-accretion threshold, as a native module within the SUMO platform.
Keep conductors above the ice threshold.
SUMO's anti-icing applies inverse Dynamic Line Rating: instead of calculating how much current a line can safely carry without overheating, it now calculates the minimum current needed to keep a conductor warm enough to prevent ice accretion. It ships as a native module within the same operational environment as Dynamic Line and Transformer Rating.
Inverse DLR for ice prevention
Using the same span-level thermal model that powers Dynamic Line Rating, SUMO computes the minimum current required to hold each conductor above the ice-accretion threshold under the prevailing and forecast weather conditions.
Native to the platform
Anti-icing is not a bolt-on. It runs as a native module within the same SUMO environment, sharing the weather modelling, control-room integration and continuous archive that operators already rely on for line and transformer ratings.
Operating Model
Some operators choose to have both normal DLR rating and inverse anti-icing rating running in parallel for every line. Others opt to switch from one mode to the other based on a risk-of-glazing alarm issued by the national weather provider. SUMO supports both options.
