| 摘要: |
| 变压器绕组在遭受短路故障后易产生变形，传统的频率响应分析或短路阻抗分析在绕组变形检测过程中具有一定的片面性。提出一种基于信息融合和CS-SVM(布谷鸟优化的支持向量机)的变压器绕组变形故障诊断方法，通过将绕组变形相关的检测数据融合成SVM的输入样本，并放入根据人工经验训练好的CS-SVM来进行诊断。Matlab仿真结果表明，此方法具有良好的抗干扰性，能够较好地诊断出变压器绕组状态。最后再结合某变压器具体实例进行相应验证。 |

| Abstract: |
| It is easy for transformer winding to generate deformation after short-circuit fault, and traditional frequency response analysis or short circuit impedance analysis is one-sided during the process of the winding deformation detection. This paper proposes a diagnosis method for transformer winding deformation fault based on fault information fusion and Cuckoo Search Optimization based Support Vector Machine (CS-SVM). It integrates the inspection data related to winding deformation into SVM input sample and puts it in the CS-SVM trained according to artificial experience for diagnosis. According to Matlab simulation result, this method has preferable anti-interference property, which can diagnose the state of the transformer winding better. Finally, corresponding verification is conducted by combining specific example of certain transformer. |
