基于可拓理论的变压器状态综合评估

笔者基于可拓理论,提出了一种可拓评价法和可拓层次分析法相结合的变压器状态综合评估方法。首先,采用可拓层次分析法(EAHP),将变压器状态信息之间的相对重要度采用一个可拓区间数来表示,构造可拓判断矩阵,准确计算变压器状态信息指标的权重。然后,应用可拓评价法,通过计算物元之间的关联函数同时进行定性和定量分析,实现变压器状态的综合评估。实例分析证明了该方法的正确性和有效性,为变压器的状态维修提供了合理的决策依据。

Synthetic Condition Evaluation of Transformer Based on Extension Theory

Based on the extension theory,a new method of transformer condition evaluation combining extension evaluation wiht extension analytic hierarchy process was presented.EAHP was applied to calculate the weight of the transformer condition information,and extension evaluation was employed to create the framework of transformer condition evaluation.Two examples were taken to verify the validity and feasibility of the proposed method.
