介绍了一种通过有限元软件进行温度场建模计算载流量的方法。对温度场建模时, 由于材料参数的不确定性, 会导致建模结果存在误差, 文章提出一种根据弦截法原理来修正载流量计算参数的算法, 通过与分布式光纤传感测温设备获得的实测数据比对, 得出参数修正后的误差小于修正前, 验证了该算法的有效性。

This paper describes a method to calculate the ampacity through thermal modeling using finite element modeling software. In the thermal modeling, the uncertainty of material parameters may cause error. In order to reduce the error, we propose an algorithm to amend the ampacity calculation parameters according to the principle of secant method algorithm. By comparing with the real data measured by the distributed optical fiber sensing temperature measurement equipment, the error of corrected data is less than that of uncorrected data, which confirms the validity of the algorithm.
