摘要
本文提出外加电压源时间周期有限元法计算变压器中各向异性非线性时变电磁场,并推导出相应代数方程组的对称牛顿—拉夫逊单步法迭代格式,最后给出实际算例。
In this paper, the time periodic direct finite element method under voltage source is proposed in order to calculate the anisotropic and nonlinear transient magnetic field in transformers and a symmetric Newton-Raphson single step formulation for anisotropic and nonlinear problems is derived.
