摘　　要：将二端口网络级联方法应用到不考虑绕组间互感影响的单绕组变压器频率响应函数的计算中,通过对单绕组变压器二端口网络单元的划分,建立了单绕组变压器绕组二端口网络模型,以快速获取变压器绕组等效电路模型频率响应曲线,并验证了所述方法的正确性。研究表明,利用此方法能大大减少参数均匀的单绕组变压器FRA曲线建立的工作量。The cascade method of two port network is applied to the calculation of frequency response function of single winding transformer without considering the influence of mutual inductance between windings in this paper.By dividing the two port network units of single winding transformer,the two port network model of single winding transformer winding is established to quickly obtain the frequency response curve of transformer winding equivalent circuit model,and the correctness of the method is verified.The research shows that this method can greatly reduce the workload of FRA curve establishment of single winding transformer with uniform parameters.
