基于面向对象的黑板型变压器故障诊断专家系统研究

将面向对象的技术引入到变压器绝缘故障诊断专家系统中，建立了适合于变压器绝缘故障诊断的黑板模型结构。同时还建立了多专家合作变压器绝缘故障诊断专家系统，提出了富有创意的专家意见不一致时的综合分析和解释机制，并以实际诊断例证检验了该专家系统的有效性和可靠性。应用模糊综合评判法和模糊神经网络判别法，创造性地将变压器故障诊断研完从故障性质的分析深入到故障部位的确定，提高了专家系统的实用性。

Research on Object-oriented Blackboard Expert System of Fault Diagnosis in Power Transformer

The object oriented technology is introduced to the expert system of insulation fault diagnosis in power transformer. An object oriented blackboard expert system of fault diagnosis in power transformer is designed. The paper sets up the multi-expert cooperating expert system of insulation diagnosis in power transformer and put forward integrated analysis conclusion according to the disagreement of the experts. The diagnosis results proved that the expert system is efficient and reliable. By the methods of fuzzy integrated diagnosis and fuzzy neural network, the research of fault diagnosis in power transformer is further from fault property analysis into fault location determination and lead to the increase of the practicability of the expert system.
