Cable core temperature prediction method and system based on finite element method

The invention discloses a cable core temperature prediction method and system based on a finite element method, and the method comprises the steps: carrying out the finite element analysis through the structure parameters, thermal parameters, boundary conditions and the like of a cable under the condition of combining the skin temperature of the cable, obtaining sample data, and simulating the temperature of a cable core through the finite element method; and the temperature of the cable core is predicted in combination with SOM-LSTM. While the temperature of the cable core is measured, the prediction precision is improved, the cost is reduced, and the internal structure of the cable is protected. 本发明公开了一种基于有限元法的电缆缆芯温度预测方法及系统包括：本发明在结合电缆表皮温度的情况下，利用电缆的结构参数、热参数以及边界条件等进行有限元分析获得样本数据，利用有限元法模拟缆芯温度，进而结合SOM-LSTM预测电缆缆芯的温度。在完成电缆缆芯温度的测量的同时，提高了预测精度，降低了成本，保护了电缆的内部结构。
