Rating of equipment found in power systems depends not only on the properties of the asset (e.g. diameter of conductors), but on many ambient factors, as well. This approach enables us to calculate rating of equipment in real time, based on the actual values of influential parameters. Dynamic line rating is capable of maximizing ampacity of power lines and transmitted power through the network by monitoring and measuring ambient parameters in real time. Calculating dynamic rating has plenty of economic advantages in the field of uprating equipment, as opposed to other uprating methods like installing new, expensive assets. Dynamic line rating is based on different modelling and calculations techniques of line rating.

By examining, comparing and developing different existing line rating methods and modelling techniques that emerged in the last decades, the objective is to develop a new, more efficient dynamic line rating system. The new method includes the advantages of older models, optimizes the number and use of influential parameters, allowing the design of a more efficient, easily applicable, financially more beneficial rating system, which not only estimates ampacity in real time, but forecasts it on the short-, medium- and long range.
