The Construction of Abnormal Event Recognition Expert System for HTR NPP

In order to meet the needs in the development of Computerized Operating Procedures System of HTR NPP, an abnormal event recognition expert system is built for abnormal event operating procedures entrance monitoring of HTR NPP, using the method of fuzzy Petri net which has excellent graphic description ability and rigorous mathematical theory, in view of the problems existing in traditional expert system such as weak knowledge expression ability and low reasoning efficiency. Compared with the traditional methods, method in this paper has great advantages in strengthening the structural features and knowledge expression ability, improving the reasoning efficiency and convenient for computer programming. The simulation of a typical case of abnormal events recognition verifies the feasibility and effectiveness of the designed system, laying the foundation for the development of COPS of HTR NPP.
