- Abstract
In recent times, great emphasis is given to operate the power system networks more efficiently to reduce power price. To achieve higher line ratings, the transmission system operators resort to dynamic line ratings. In some cases, to increase the ratings further, short-time transient ratings are used. When the transmission line conductors are pushed to the limits, it is important to ensure that the real-time ratings and the conductor temperatures are estimated accurately. For this purpose, often the conductor thermal model is used to simulate the time-varying conductor temperature. It is equally important to validate the simulation model used to ensure the accuracy of temperature prediction. This paper addresses three different methods of experimentally validating the simulation model. Experimental results are compared with the simulated results along with practical limitations of the methods.
