一种基于SVM算法的电力变压器机械故障智能诊断模型
Intelligent Diagnosis Model of Mechanical Fault for Power Transformer Based on SVM Algorithm
摘要
Abstract
Vibration analysis method is a non-electric diagnostic method for mechanical fault of transformer.The method can diagnose such faults as winding deformation or core looseness inside the transformer by analyzing vibra-tion characteristic of the surface of transformer oil tank.SVM,as a new machine learning method,can train and ob-tain a classification model with strong generalization ability under the condition of small samples.Based on the vibra-tion signal and SVM algorithm,an intelligent diagnosis model of transformer is constructed.The SVM training data set is constructed on the basis of collection of hundreds of groups of vibration signal data trial transformer and spec-trum feature extraction.The one classυ-SVM fault diagnosis model is trained and good results are achieved.The effec-tiveness of the model is verified,which can provide some references for the related researchers.关键词
