摘　　要：为了方便研究变压器绕组故障,采用频率响应的分析方法,开发出了变压器绕组故障仿真模拟系统。参照国家标准的测试方法,对变压器绕组模型进行了测试、分析,得到了绕组变形的频率响应特性曲线。经过仿真模拟,找出了系统的固有频率。实验表明,在固有频率附近幅值响应有明显的变化。For the convenience of transformer winding fault study,the authors developed a transformer fault simulation system with the frequency response analysis（FRA）.According to the national standard test methods,the frequency response of winding deformation curve was obtained through testing and analyzing the transformer winding model.The natural frequency of the system was identified by simulation.Experimental results indicated that the amplitude response changed obviously close-by the natural frequency.
