The main concept of our Ampacity model is to make a decision-support process for system operators, which can be practically applied. Ampacity model is not only used to increase the line rating, but also to increase operational safety. Therefore, the real-time load of the line can be lower than the static rating, when the actual weather parameters show the worst scenario than the parameters which was used for static rating calculation. In this case, the thermal overload and the violation of safety margins can be avoided by limiting the ampacity.
Ampacity is defined as the maximum current, in amperes, that a conductor can carry continuously under the conditions of use without exceeding its temperature rating limit value. It is the most important output parameter of any Dynamic Line Rating (DLR) expert system.
