摘要
变压器励磁涌流的准确计算是一个十分困难的问题。提出用非线性时步有限元法来模拟变压器励磁涌流的动态过程。采用的数学模型将非线性时变电磁场有限元方程与电压源下的电路微分方程耦合在一起，并考虑铁心的磁饱和与磁滞特性。仿真结果与实验曲线基本吻合。
It aims carry out a two dimensional non linear, time stepped Finite Element simulation of inrush currents in sinale phase transformers. The model couples the finite element electromagnetic equations with the electrical circuit equations. the saturation and hysteresis characteristics of the core material in transformers are taken into account.
