| 摘 要： | 本文把混合有限元法和变网格法结合起来,构造出适合于求解与时间有关的偏微分方程问题的计算格式。通过对变压器过励磁情况下的非线性时变涡流场的分析计算,证明这种方法比传统的有限元法具有灵活性大、构造插值格式简单和精度高等显著优点。

| Abstract: | A fully discrete mixed finite element method with moving grids are presented for analysis of nonlinear time-dependent eddy current field in transformer which operating under overexcited condition. Through the comparison of calculated and measured results, this method has the advantages of more flexibility, simpler formulation and higher accuracy than the conventional FEM. |
