Research Of Transmission Line Fault Diagnosis Expert System

As the hub of Power delivery system, high-volt transmission-line plays an important role so that its fault will threaten the safety of modern power system. When a fault in transmission-line occurs, it becomes very hard to identify fault fast and correctly. One of the most important and active in artificial intelligence application areas is expert systems (ES). More problems of transmission-line can be solved by expert system.According to the features of the transmission line's fault, a few of traditional fault-diagnosis methods are compared, and export system is researched which is more advantage than traditional methods. Combine with artificial intelligence, database and fuzzy theory, this paper construct a general fault diagnosis expert system model which the knowledge management system be independent of the inference mechanism. And the fault diagnosis expert system was designed using object oriented programming, function and performance has been test in laboratory environment.With adapting a series of fault types to knowledge sample, the transmission line fault diagnosis expert system can accurately evaluate fault types, achieve anticipated goal. And high performance knowledge acquisition module have constructed, this model has the better and expandability.
