Research on the Optimization Method for Calculating the Maximum Load of Buried Cable Cluster

Accurately calculating the maximum load capacity of buried cable clusters is crucial for ensuring the safety and reliability of power transmission and enhancing transmission capacity. This paper proposes an optimized method for calculating the maximum load capacity of buried cable clusters based on IEC standards, taking into account temperature field distribution. Using this method, the maximum load capacity of typical buried cable clusters was optimized, and the temperature field distribution of the cable clusters under different maximum load conditions before and after optimization was calculated and analyzed. The results show that after optimization, the temperature field distribution of the cluster buried cables becomes more uniform, thereby improving their transmission capacity. Finally, a simulation model was established using COMSOL finite element simulation software to verify the effectiveness and accuracy of the proposed optimization calculation method.
