To deal with the uncertain factors and high real-time performance, the elements of 110 kV substation is divided into three kinds of basic correlated nodes by the cause-effect relationship between delay protection equipments based on the protection information, the three kinds of basic correlated nodes are component fault, protection action and breaker tripping or refusing to trip. And then multiple attribute evaluation model is established to determine the causality intensity of associated nodes in FCE-Nets. The correlation function of electric parameters in failure is used to improve the missing information and checking mechanism. Finally, a substation fault diagnosis scheme is proposed based on multiple attribute evaluation and FCE-Nets. With the actual substation application analysis, the proposed scheme is compared with the existing method of fault diagnosis and the results verify the effectiveness of the scheme.
