- Abstract
Based on posterior probability of support vector machine, the analysis of dissolved gases in oil and the data of electrical tests are used comprehensively to recognize internal fault positions of the power transformer. This method not only inherits the advantages of the support vector machine for small samples, strong generalization ability and so on, but also provides the fault information of the power transformer by the form of probability. The output results not only provide the breaking down probability of the inner winding, tap changer and leads, iron core, structure and magnetic shielding body, insulating barrier and other parts, but also express the degree of credibility of conclusions. It adapts to the uncertainty characteristics of the fault positions. After analysis of examples, the validity of the model is verified.
