Dynamic line rating is nowadays much more advanced than anticipated, all while using a brand new name in SMARTLINE TCF, thanks to the exquisite work done by Lindsey Manufacturing. This goes way beyond regular DLR and offers fully operational forecasts for transmission capacity.

SMARTLINE TCF is not using the tag “smart” as a simple marketing method. The idea behind the system is that transmission capacity will be forecasted based on actual data that is measured, as opposed to estimations. Installation is fast and simple, with zero outages being necessary. Combine this with out-of-the-box, dependable satellite communications, together with cloud technology and you have access to a fully modern system.

The Smart Rating

The traditional, often-used transmission line static rating is intentionally created in order to be highly conservative. Conservative ratings are always going to offer limited grid operations. SMARTLINE is different in the sense that it informs utilities of the true handling capacity for power of a specific metered transmission line.

When comparing the new SMARTLINE system with the first DLR (dynamic line rating) methods, SMARTLINE offers ratings that are much better. They are developed through active learning about how conductors behave in connection with conductor temperature, load, clearance-to-ground and ambient temperature.

Transmission Capacity Forecasting

SMARTLINE TCF is really effective because of the fact that forecasts are highly accurate in regards to power carrying capacity. We are looking at systems that ensure forecasted capacity will comply with the electrical clearance limits. At the same time, conductor thermal overloads are going to be fully avoided.

Forecasts are going to be available in 1-week or 1-hour increments with an efficiency of 98%. SMARTLINE is great for operations, planning and engineering functions. At the same time, it is useful for an EMS system integration in real-time and day-ahead markets. There is no longer a need to have operational limits and dispatch, which are often connected with the fixed capacity assets. These are replaced with transmission pathways that have real-time condition capacities.

SMARTLINE DLR – A Next Generation DLR System

DLR (dynamic line rating) basically has one main meaning: understanding the maximum current carrying capacity for a line while making sure that thermal damage is completely avoided. Through the use of SMARTLINE DLR you gain access to the basic and traditional DLR and a highly more advanced system. SMARTLINE TCF is now built based on clearance enhanced DLR, which is the standard of SMARTLINE DLR.

Basically, the improved DLR rating happens as Lindsey TLM conductor monitors are put in place on spans that are clearance-limited. This guarantees clearance requirements will not be violated while thermal damage risks are eliminated.

Final Thoughts

The bottom line is that this is new technology that is much more advanced than what was used in the past. It brings in much better results for power distribution thanks to monitoring everything that is happening. The line rating is much more advanced and you can choose whether or not you use it as the regular option or you just go for the new technology.
