The Development of a Platform for Assessing Real-Time Dynamic Thermal Rating for the Overhead Transmission Lines

The importance of Real-Time Thermal Rating (RTTR) lies in its crucial role within modern power transmission systems as it provides a dynamic and datadriven approach to assessing the thermal performance of overhead transmission lines. In this study, an RTTR platform is developed to enhance the reliability and efficiency of power transmission systems. Real-time weather data, line parameters and location information are employed by the platform to estimate the current thermal ratings of overhead transmission lines. A comparison of the accuracy and effectiveness of the proposed platform with those of the conventional static thermal rating method is conducted, and critical spans are identified to ensure minimum electrical clearance, prioritizing the safety of both individuals and equipment. The developed web-based RTTR platform has the potential to grant power transmission system operators proactive management tools, representing a substantial advancement over traditional static thermal rating methods.
