摘　　要：通过对灰色关联度分析中的分辨系数的分析,得出了分辨系数的性质和分辨系数的取值原则。在此基础上,提出了面积关联度分析的概念和方法。通过实例分析,验证了应用面积关联度法诊断变压器绝缘故障性质的有效性。该方法也可用于对变压器故障的部分定位分析。Through the analysis of distinguishing coefficient in the analysis of degree of grey incidence, the properties ofdistinguishing coefficient and the rule of its assignment areobtained, and on this basis the concept of degree of areaincidence is put forward. By the analysis of practical example, it is proved that the attributes of insulation fault can beeffectively diagnosed by the degree of area incidence and it can be also used in the fault location of transformer.
