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.
With the help of modern analysis software ANSYS and MATLAB, electromagnetic analysis and performance calculation of traction transformer of a 350 km / h EMU are carried out.Firstly, the magnetic field analysis based on ANSYS is performed, and the inductance that reflects the electromagnetic coupling between the windings is calculated Coefficient (matrix) .And then based on the transformer circuit structure to build a simulation model based on MATLAB, calculate the short-circuit impedance and steady-state short-circuit impedance and no-load performance parameters between the two windings of the transformer.Experimental results show that this The combination of methods to simulate the effectiveness of such transformers.
