Expert System of Electric Pump Well Condition Diagnosis

In order to realize the intelligent diagnosis of the electric pump and the motor working condition during the operation period of the electric pump well, an expert system based on fault tree and rete algorithm is realized. Through the analysis on the fault characteristics of the electric pump well, established the fault tree and knowledge base that support electric pump and motor working condition diagnosis, then combined with the rete algorithm based on production rule, which is used to obtain the diagnosis result of working condition, and gives the corresponding optimization suggestion. At last, based on the basic data and motor test data of electric pump well, the working conditions of 57 wells were diagnosed. The result shows that the diagnosis results are consistent with the practice, which improves the efficiency and accuracy of the working condition’s fault location.
