FAQs

How are dynamic line ratings used in transmission operations?

The use of DLR in operations provides grid operators with more visibility into their system and more control over their grid. Seamlessly integrated into the control room EMS, they optimize transmission by identifying the true thermal limits of overhead conductors. Grid operators can use these ratings in real-time and day-ahead markets and operations.

How can dynamic line ratings inform the planning process?

When DLR technology is used in operations, historical line ratings can be analyzed to create probabilistic line ratings which can be available on a seasonal, monthly, or more granular level to inform the planning process. The additional data regarding the hourly / sub-hourly thermal rating that comes from DLR can help maximize the efficiency of transmission planning.

How much transmission capacity improvement can I expect using Dynamic Line Rating?

Most utilities that use LineVision DLR experience average capacity gains upwards of 30%, with some reaching the triple digits on certain lines. The capacity change will vary by a large set of variables, including; region, conductor/tower type, current rating methodology, utility risk profile, and climate. During the sales process, LineVision conducts rigorous profiling studies to analyze target lines and scope out a project with maximized benefit.

If we already use Ambient Adjusted Rating (AAR), how is Dynamic Line Rating different?

(DLR) differs from AAR by using real-time weather and wind data, resulting in more accurate ratings. DLR provides enhanced operational awareness and risk reduction by avoiding overstated capacity and detecting potential anomalies. Additionally, sensor-validated DLR offers increased accuracy and deep learning capabilities alongside the use of software-only models.

Is your system compliant with NERC-CIP requirements?

LineVision’s line rating systems are designed to fully comply with NERC-CIP requirements if deemed in scope by the utility.

How does LineVision protect line rating data?

LineVision has successfully achieved ISO 27001:2022 certification for our Operationalized LineRate solution, demonstrating the comprehensive measures we have implemented to ensure the confidentiality, integrity, and availability of our customers' data. We have undergone rigorous 3rd party audits and assessments, which are updated annually, affirming that our information security controls meet the stringent requirements of the standard.

How does Dynamic Line Rating compare to re-conductoring or new transmission?

DLR can be deployed on new transmission projects, existing infrastructure, or to support the outages required for rebuilds and reconductoring. DLR is 5-7% of the cost of traditional transmission upgrades and can be installed in months without the need for outages.

Does every span of a transmission line need to be monitored with a sensor?

LineVision’s scoping process identifies the most limiting spans along a line that require field monitoring. A typical installation will monitor a full range of sites with differing angles of incidence to wind, topography/sheltering, conductor type, and maximum operating temperature.

How do you evaluate the accuracy of your line ratings?

LineVision’s ratings model is continually trained and improved using sensor-based data as feedback. This training improves accuracy and confidence in delivered ratings. The model incorporates statistical distributions to deliver confidence intervals that provide a comprehensive rating product.

How many sensors are required to provide accurate capacity ratings?

Hardware requirements are dependent on project scope and complexity; however, one sensor per 2-3 miles is a reasonable estimate.

How does LineVision support NERC FAC-008 compliance?

LineVision can provide documentation of DLR methodology to support FAC-008 documentation requirements.

Is LineVision's software able to manage facility ratings?

Yes, LineVision's software integrates non-conductor facility limitations, allowing complete facility ratings management including elements such as transformers, switches, wave traps, etc. as potential limiting factors alongside the conductor's Dynamic Line Ratings.
