摘要(Abstract)：

变压器数字孪生技术的实现很大程度上依赖于设备内部多物理场的快速计算。为此，采用改进的RBF（径向基函数）响应面法，建立POD（本征正交分解）模态系数关于绕组工况的响应面模型，进而结合降阶模态快速计算变压器绕组温度场。通过与全阶计算结果对比，在100个测试工况中，降阶模型的最大平均相对误差为1.91%，计算100个测试工况仅需31.26 s，效率约为12核并行全阶计算的61 266.79倍。计算结果表明，所提出的结合响应面法的POD降阶算法具有较高的计算精度和效率。
The realization of digital twinning technology for transformers largely depends on the rapid calculation of various physical fields within the equipment. Therefore, the response surface methodology based on enhanced radial basis function(RBF) is employed to construct a response surface model of the POD(proper orthogonal decomposition) modal coefficients for winding conditions and then quickly calculate the transformer winding temperature field based on reduced order mode. Upon comparison of these results with those obtained from full-order calculations, it is observed that the maximum average relative error of the reduced-order model is 1.91% across 100 test cases. Remarkably, the calculation of these 100 test cases is completed in a mere 31.26 seconds, signifying an efficiency level approximately 61,266.79 times superior to that of the 12-core parallel full-order calculation. The computational findings affirm the high computational accuracy and efficiency of the proposed POD reduced-order algorithm founded on response surface methodology.
