Fault Diagnosis On Resonance In Power System Of Large Enterprise Based On Fuzzy Expert System

In this paper, we mainly study resonance fault in power system. On one handmore and more complicated power network structure makes fault diagnosis moredifficult, on the other hand large enterprise needs safer and safer power network withthe highly development of modern social economic. It is necessary to find exact faultdiagnosis method to keep network safe.The paper analyzes the characteristics of and the factors result in resonanceand brings forward a way of fault diagnosis expert system based on fuzzy theory byapplying theory of artificial intelligent, database and fuzzy theory. The system adoptsa way of knowledge expression based on fuzzy creation way of rule because of theuncertainty of fault phenomenon, applies the technology of the ER database toestablish the database, adopts positive inference control policy in inference module,applies the object-oriented technology to realize the system.
