基于FAHP的电力变压器系统的脆性分析

由于复杂系统具有层次结构，本文采用模糊层次分析法(FAHP)对复杂系统进行了脆性分析。由模糊层次分析法得到了子系统(或元件)的相对重要度排序向量，通过定义脆性激发度及激发阈值，对复杂系统的脆性是否被激发进行了理论的分析。通过分析，可以找出复杂系统中的脆性元件或因素，对其进行重点监测，使得最大程度的避免了脆性的发生。最后本文以变压器故障的模糊层次分析为例，分析了变压器故障的因素的相对重要度，找出了易使变压器崩溃的脆性因素，说明进行复杂系统的脆性分析是必要的。

The Brittle Analysis of the Electric Power Transformer Based on the FAHP

There is hierarchical structure in complex system. In this paper, we analyze the brittleness of complex system with the Fuzzy Analytic Hierarchy Process(FAHP). We obtain the relative importance degree order vector of the subsystem(or element)by the method of FAHP. Through defining the brittleness waken degree and waken threshold value, we academic theoretic analyze if the brittleness of complex system can be waken. We can find the brittle element and factor of complex system and watch at it. It will avoid the happen of brittleness in the maximal degree. At last, we example for the fault of transformer and analyze the relative importance degree of factor of it. Moreover, we find the brittle factor of breakdown of brittleness. It shows that it is essential to analyze the brittleness of complex system.
