Real Time Thermal Rating Distributed Fiber Optic Sensing

Dynamic line rating (DLR), also known as real-time thermal rating (RTTR), is an electric power transmission operation philosophy aiming at maximizing load, when environmental conditions allow it, without compromising safety. Research, prototyping and pilot projects were initiated in the 1990s, but the emergence of the "smart grid" stimulated electric utilities, scientists and vendors to develop comprehensive and sustainable solutions. WebDynamic ratings are possible for offshore wind projects due to time varying cable current and the slow thermal response of buried cables There are no internationally accepted standards for dynamic ratings although research is on-going at CIGRE. WebDynamic ratings, that is ratings which account for ambient conditions, are considered to increase the effective thermal rating. Therefore ATC is concomitantly improved. A key component to dynamic ratings is the inclusion of sensory information. Measurements are integrated with a dynamic line rating algorithm in Section 3. small crowd noise
