基于层次分析法和粗糙集的变压器状态评估研究
|
摘要
针对变压器状态单一评价方法存在的不足和影响变压器性能的状态量错综复杂的特征,建立基于层次分析法和粗糙集的变压器状态评估模型。对变压器部件、状态量进行层次结构划分,借鉴专家经验并以层次分析法求得各部件、状态量的主观权重;结合变压器测试数据,运用粗糙集理论分析出各部件、状态量的客观权重;将主、客观权重进行优化组合,以反映各部件、状态量在变压器综合状态评估的权值。运用该模型对两台不同类型变压器的检修数据进行分析并得出变压器状态评价结果,将该结果与实际变压器检修状况对比,结果表明,此模型具有全面准确地评价变压器状态的能力。
In view of the problems of single transformer condition evaluation method and the complicated factors thataffected the performance of transformer,a state assessment method of transformer based on AHP(analytic hierarchyprocess,AHP)method and rough set theory is proposed. Combined with the experience of experts,the AHP methodis used to obtain the subjective weights of the components and state quantities divided by the hierarchical structure;By the test data of transformer,it is adopted to analysis the objective weight of each part and state quantities by roughset theory,the optimized combination weights,which is the combinatorial optimization of subjective and objectiveweights,reflected in the proportion of the parts,state quantities of the running state of transformers. The model is ap-plied to analyze the maintenance data of two different types of transformers and the results are compared with the ac-tual transformer maintenance status,it has proved that this model has the ability to evaluate the transformer statuscomprehensively and accurately.
