Extension set is an emerging set theoryfor solving incompatible problem systems. Using extension set theory, this paper presents the formal conceptions ofstrategy and key strategy, establishes their matter-element models, and gives the strategy development method.展开更多
基于可拓理论,在传统油中溶解气体分析DGA(Dissolved Gas Analysis)三比值法基础上,提出一种可拓集变压器故障诊断方法。首先,建立三比值法的物元模型,然后给出点对区间的可拓相关函数,利用该函数计算进行变压器故障诊断。仿真计算证明...基于可拓理论,在传统油中溶解气体分析DGA(Dissolved Gas Analysis)三比值法基础上,提出一种可拓集变压器故障诊断方法。首先,建立三比值法的物元模型,然后给出点对区间的可拓相关函数,利用该函数计算进行变压器故障诊断。仿真计算证明该方法能克服传统三比值法的编码不全,不能诊断多重故障的缺陷,提高了诊断精度。展开更多
