In the bustling world of power system operations, precision and reliability are paramount. Ampacimon, a leader in dynamic line rating technology, has introduced a groundbreaking solution that ensures uninterrupted accuracy even when sensors go offline: WindFallBack.

‍

Imagine a scenario where a sensor, diligently monitoring a power line, suddenly goes off. Traditionally, operators would revert to Ambient Adjusted Rating (AAR), a method that often lacks the precision needed for optimal performance. However, Ampacimon's WindFallBack offers a superior alternative.

‍

After a sensor has been installed on a line for more than six months, Ampacimon's system has accumulated a wealth of real-time data. This data is not just stored; it is meticulously analyzed to create accurate forecasts. When a sensor becomes non-operational, WindFallBack steps in, utilizing this rich data to provide a rating that is close to dynamic line rating (DLR). This means operators can continue to benefit from enhanced accuracy, avoiding the pitfalls of reverting to AAR.

‍

The impact of WindFallBack is profound. Take, for instance, a European leading TSO who adopted this innovative solution. The results were remarkable: WindFallBack provided a +20% gain over AAR, showcasing its ability to maintain high performance standards even in challenging situations.

‍

Compared to DLR results, the WindfallBack only indicated a -8% capacity loss, while this could have been much worse compared to AAR model (-23%).

‍

On this graph, we can clearly see how the dark blue line representing the WindFallBack’s results stands as a solid alternative to DLR, showing better results than AAR (light blue).

‍

Ampacimon's WindFallBack is more than justa fallback option; it is a reliable safety net that ensures power systemoperators can count on accurate line ratings, no matter the circumstances.

‍

With WindFallBack, Ampacimon continues tolead the way in dynamic line rating technology, offering solutions that areboth innovative and dependable.
