Ampacity Analysis and Optimization of AC XLPE Submarine Cable Based on Genetic Algorithm

The steady-state thermal circuit model based on IEC 60287 standard is widely used to analyze the ampacity of submarine cables due to its high efficiency. However, the value selection of some parameters only refers to the range given by IEC 60287 standard in the existing thermal circuit models, without specific suggestions. In this paper, a method on the optimization of steady-state thermal circuit model of AC XLPE submarine cables using genetic algorithm (GA) is proposed, which improves the accuracy of the steady-state thermal circuit model.
