What is smart about SMARTLINE? Transmission capacity forecasts built on actual measured data, not estimates. Simple and fast installation- no line outages required. Dependable, out-of-the-box ready satellite communications.
SMARTLINE informs the utility of a transmission line’s true power handling capacity. Compared to first generation dynamic line rating (DLR) methods, SMARTLINE ratings are developed by actively learning how the conductor behaves with regard to conductor temperature, ambient temperature, load and the conductor’s exact clearance-to-ground. For a detailed discussion of how first generation DLR systems differ from SMARTLINE, download this whitepaper.
SMARTLINE-TCF – Transmission Capacity Forecasting
The SMARTLINE-TCF platform develops highly accurate forecasts of transmission line power carrying capacity. The platform ensures capacity forecasts comply with electrical clearance limits while at the same time avoiding conductor thermal overloads. Forecasts can be provided in one-hour to one-week increments with 98% or better confidence. SMARTLINE-TCF is ideal for engineering, operations, and planning functions, as well as for integration with EMS systems in both day-ahead and real-time markets.
SMARTLINE‐TCF eliminates the dispatch and operational limitations associated with fixed capacity transmission asset and replaces them with a living set of transmission pathways whose capacities reflect real-time conditions. SMARTLINE is key to a true “smart” transmission grid. Download a complete description here.
SMARTLINE-DLR: Next Generation DLR
Dynamic line rating has always had one meaning: What is a line’s maximum instantaneous current carrying capacity while ensuring no thermal damage occurs. SMARTLINE-DLR can provide either this traditional – and basic – DLR or a more operationally useful clearance-enhanced DLR. SMARTLINE-TCF is built upon the clearance enhanced DLR of SMARTLINE-DLR.
This improved DLR rating results when the Lindsey TLM conductor monitors are installed on clearance-limited spans. The use of clearance-limited spans ensures clearance requirements are not violated while also eliminating risk of conductor thermal damage. If the selection of monitored spans is given no consideration as to clearance limit monitoring, SMARTLINE-DLR provides basic DLR, consistent with traditional DLR solutions.
Predicting conductor life-cycle is a difficult task. The Conductor Asset Health module for the SMARTLINE system provides an accurate, live assessment of conductor health. The learning-based conductor behavior model used by SMARTLINE allows the system to track conductor life as a percentage of the conductor’s maximum lifecycle creep.
Ensuring clearance is vital. Yet static ratings and traditional dynamic line (DLR) ratings systems depend on estimates of sag, which itself only estimates clearance. SMARTLINE doesn’t use estimates of estimates; SMARTLINE looks directly at measured clearance.
SMARTLINE uses Lindsey TLM monitors which provide real-time LiDAR measurements of conductor clearance. SMARTLINE is the ONLY continuous line rating system that uses actual clearance measurement information, not estimates of sag.
SMARTLINE forecasts and ratings result from looking continuously at the data that directly impacts a transmission line:
SMARTLINE is a learning-based system that makes extensive use of statistical correlation and forecasting techniques to actively learn over time how line behavior varies with weather and load. This reliability-based nature means you can depend upon SMARTLINE as it uses the right data to provide reliable results.
After learning, SMARTLINE can provide forecasts of capacity from an hour to days in advance.
Cloud-based server implementation ensures that you are always running the latest version of SMARTLINE.
The easy, secure and fast way to take advantage of SMARTLINE. All data is passed to the secure Lindsey Cloud server where SMARTLINE resides; always up-to-date, constantly monitored. No IT overhead, no additional IT expense. Weather data is similarly set up by Lindsey. The result is a simple data feed providing real-time capacity ratings and the forecasted ratings of your choice.
