# Dynamic Rating of Three-Core XLPE Submarine Cables for Offshore Wind Farms
## 7 Conclusions  
This article shows how to determine internal cable parameters and model the thermal ladder network to represent a three-core XLPE submarine cable with heat dissipation from the surroundings. It proposes an iterative method combining two approved standards to make a dynamic rating of three-core XLPE submarine cables by an evaluation of the transient temperature behaviour in the centre of the conductor. The method is validated in comparison with an FEM-based simulation and shows, in the above specific case, a maximum deviation of 1.19 \({}^{\circ}\)C. In comparison with an FEM-based approach, the method presented in this article is remarkably faster at evaluating the temperature progress and will, in most cases, be a good first-shot computation of the cable rating phase of a project. [PERSON] and [PERSON] developed methodology, performed the analysis, modelling and software simulation study, write the draft manuscript and the revised version. [PERSON] supervised the research activities: In addition, he reviewed and commented on the original and revised manuscripts. This study was made as a part of the education Electrical Power Engineering at the 7 th semester, at the University of Southern Denmark, Odense, Denmark. Thanks to the cooperating companies Energinet Eltransmission A/S and Vattenfall Wind Power A/S for the contribution of the needed data and expert knowledge, when needed.
