Study On Expert System For Failure Diagnosis Of Power Transformer

According to the characteristics of failure diagnosis of power transformer, this paper advance the scheme that integrate the infrared ray technique with expert system to carry out the failure diagnosis of power transformer. When the expert system is built, the blackboard-style and brand-new multi-expert cooperating framework is adopted, the integrative mathematical model is erected. In the aspect of hardware, the modern communications way with Field Control Bus is introduced. The whole project about the hardware and software of system is made and a part of program is brought to success.This paper deeply study the basal theory about the top and new technology that is infrared technique,generally understand and compare the familiar infrared instruments , analyze the factors which may influence measure outcome, bring forward some corresponding details and offer a few ways to correct the measured infrared signal.In the research of the knowledge-base for expert system ,the Object Oriented technology is used to build it ,which can make the complicated expert knowledge layered and distributed. The knowledge-base with such structure hold the excellence which include high-efficiency,credibility and facile maintenance. The rules,cases ,positive-negative reasoning and other forms are used as reasoning manner. In the term of layout and search, many ways are used simultaneously, going with the layering and modularization of system. It bring the search and reasoning of system efficient and exact, multi-expert cooperating easy. In this paper, author built a comprehensive diagnosis expert system mathematical model. The surroundings factors,in-out of object,infrared signal and other signal are used as input ,and case comparing is referred, all the this cause the real comprehension of system.The exoteric thought is used to design the hardware and software. This accord with the characteristic of Visual C++, satisfy with the need of the ceaseless expansion or updating for expert system.Totally ,this system has novelty thought, simple structure, efficient diagnosis, easy maintenance, facile updating and upgrading and other excellences, possess amplitude application value and research foreground.
