Wind Turbine Fault Diagnosis System Based on A Fuzzy Expert System

摘要

A fuzzy expert system which can simultaneously support many kinds of rules including fuzzy production rule, fault tree and decision tree in a unified framework are researched. Fuzzy rete algorithm is adopted to speed up the fuzzy reasoning chain. A wind turbine diagnosis expert system is developed based on the fuzzy expert system. Experiment data is employed to verify the feasibility of the inference engine, and the results show that with proper knowledge imported the misdiagnosis rate is low, the inference process can be exported and the match degree of the health rule can be used as a health state indicator.
