On-Line Condition Monitoring using Computational Intelligence

C. B. Vilakazi, T. Marwala, P. Mautla, E. Moloto

摘要:

本文提出了套管状态监测框架,使用多层感知器(MLP),径向基函数(RBF)和支持向量机(SVM)分类器。框架的第一级确定套管是否有故障,而第二级确定故障的类型。使用溶解气体分析法分析套管中的诊断气体。MLP在精度和训练时间方面比SVM和RBF具有更好的性能。此外,在线套管状态监测方法,这是能够适应新获得的数据介绍。这种方法能够适应由传入数据引入的新类,并且使用使用MLP的增量学习算法来实现。引入新数据后,测试结果从67.5%提高到95.8%,引入新条件后,测试结果从60%提高到95.3%。平均而言,框架对其决策的置信度值为0.92。

英文摘要:

This paper presents bushing condition monitoring frameworks that use multi-layer perceptrons (MLP), radial basis functions (RBF) and support vector machines (SVM) classifiers. The first level of the framework determines if the bushing is faulty or not while the second level determines the type of fault. The diagnostic gases in the bushings are analyzed using the dissolve gas analysis. MLP gives superior performance in terms of accuracy and training time than SVM and RBF. In addition, an on-line bushing condition monitoring approach, which is able to adapt to newly acquired data are introduced. This approach is able to accommodate new classes that are introduced by incoming data and is implemented using an incremental learning algorithm that uses MLP. The testing results improved from 67.5% to 95.8% as new data were introduced and the testing results improved from 60% to 95.3% as new conditions were introduced. On average the confidence value of the framework on its decision was 0.92.
