The use of WAM Systems for Determining the Ampacity of Overhead Power Lines

This study expands upon previous research by focusing on determining the dynamic thermal rating (DLR) of a specific overhead transmission line. It utilizes real-time data from WAMS (Wide Area Measurement Systems), specifically using PMUs (Phasor Measurement Units). The paper presents a comprehensive overview of thermal evaluations, which are categorized into dynamic (including direct, indirect, transient, and steady state) and static (conventional) rating. Furthermore, the article examines standards that outline principles, technologies, and algorithms for estimating conductor temperature.
