The application of fuzzy logic theory and information technology in optimal maintenance of electric equipment

The performance of electric equipment can be influenced by many factors, so fuzzy logic and expert system methods are being introduced to resolve this problem and a maintenance analysis system based on fuzzy logic is founded. This system is an object-oriented one and the input information is affluent. Through applying information technology to make full use of information, it´s possible to realize optimal maintenance of equipments. In this system, data are acquired and processed by local intelligent equipment. With careful consideration, planning and sharing of data, the information for condition monitoring system can be derived. Decision making can he accomplished by software programming. Through this way, the hardware and software configuration of the condition monitoring system can be simplified. And the pressure of data communication and processing in the system can be alleviated. The efficiency of information can be improved, too. An application system for substations is listed.
