摘　　要：研究复杂电磁环境对电力系统的影响,有效的方法是通过建立电力设备的宽频模型,以模拟不同特性电磁干扰下设备响应情况。为此基于多端口网络理论,提出一种针对三端口网络的二端口等效模型。在此基础上测量了一台单相三绕组变压器宽频参数,通过电路综合及无源化处理建立其宽频等效电路。试验结果证明所建模型适用于单相三绕组变压器宽频电磁兼容分析。There is a lack of research on broadband modeling for single phase three winding transformer.On the one hand,the broadband modeling theory of multi-port components needs to be improved.On the other hand,internal electromagnetic coupling of single phase three winding transformer is complex.Based on the theory of multi-port network combined with circuit synthesis,a three-port equivalent model structure composed of two-ports is proposed.Based on the experimental results,a single-phase three-winding transformer broadband model has been build.Comparing the measured values and calculated values of port characteristics under complex electromagnetic environment,the experimental results show that the measured curve and calculated curve are in good agreement.
