| 摘 要： | 针对现有电力变压器模糊综合评判中只考虑指标模糊性而忽视随机性的问题,提出了新的基于云模型的电力变压器状态综合评判方法。采用层次分析法获取指标的权重信息,利用变权模式对定量指标权重进行修正,采用云模型对定量数据进行表述,同时考虑到了不确定性中的模糊性和随机性。实验环节证明该方法使评判结果更加接近实际,为变压器状态综合评判提供了一种有效可行的方法。

| Abstract: | This paper proposes a synthetic evaluation of power transformer condition based on cloud model.This method gets weight information by AHP,and quantitative indices modify weight by variable weight.Quantitative data are expressed by cloud model,so this method considers fuzziness and randomness of uncertainty at the same time.Finally a case is put forward,it is proved that this is an effective and feasible algorithm for synthetic evaluation of power transformer,and the results approach the real status more. |
