摘　　要：藉助于现代分析软件ANSYS和MATLAB,对一台350 km/h动车组牵引主变压器进行了电磁分析和性能计算.即先进行基于ANSYS的磁场分析,据此计算反映各绕组之间电磁耦合的电感系数(矩阵).接着根据变压器电路构成搭建基于MATLAB的仿真模型,计算了变压器两两绕组之间的短路阻抗及稳态短路和空载性能参数.试验结果证明了这种"场-路"结合的方法对这类变压器进行仿真分析的有效性.Electromagnetic field is at first analyzed by ANSYS and inductance matrix is calculated which descript electromagnetic coupling among many windings for a 350 km/h of the main traction transformer,and the eddy current loss is also studied for calculating the resistance of a winding.Then a simulation is made by MATLAB for the steady-state short-circuit and operation with no load of the transformer.The tests on some performances of the transformer verify that the analysis method of combining field with circuit is efficient for such a transformer with less windings.
