首先对一台多绕组的动车组牵引主变压器进行了基于ANSYS软件的3-D磁场分析．在此基础上，通过计算磁场能量得到了反映各绕组之间电磁耦合的电感矩阵，通过计算绕组的涡流损耗获得了其附加电阻；接着列写电路方程，用Matlab编程计算了对应多种稳态工况的特性．试验结果证明该方法是有效的．

A 3-D magnetic field for a transformer with multi-windings is analyzed by software ANSYS, the inductance matrix is obtained which describes the electromagnetic coupling between the multi-windings by calculating the magnetic field energy stored in the windings, and the additional resistance is also given out by calculating the eddy loss of the windings. The electric circuit equations for the transformer are resolved by MATLAB and some steady state performances are calculated. All the above results are verified by the tests or some given parameters.
