模糊层次分析法在变压器脆性分析中的应用

Application of Fuzzy Analytic Hierarchy Process to Analyze the Brittleness for Transformers

采用模糊层次分析法对系统脆性进行了分析。由模糊层次分析法得到了因素(或元件)的相对重要度排序矢量,通过定义脆性激发度及激发阈值,对系统的脆性是否被激发进行了理论的分析。通过分析,可以找出系统中的脆性元件或因素,可以最大程度地避免脆性的发生。最后以变压器故障的模糊层次分析为例,从变压器故障因素的相对重要度入手,找出了容易引起变压器故障的脆性因素,经检验该方法是可行的,同时说明进行系统的脆性分析是完全必要的。

In this paper, the brittleness of system with the fuzzy analytic hierarchy process (FAHP) is analyzed and the relative importance degree order vector of the factor (or element)is obtained. Through defining the brittleness waken degree and waken threshold value, whether the brittleness of system can be waken is analyzed. The brittle element and factor of system are found. Based on of the analysis the relative importance degree of fault factor, a fault transformers is taken as an example and the brittle factor of the transformer can be found. It is essential to analyze the brittleness of system.
