A Reasoning Method of Transformer Fault Causes Based on Fuzzy Petri Net

Abstract:

For a correct judgment on the fault cause of transformers with the rich knowledge in various criteria and guideline, a method of automatic reasoning for the fault cause through fuzzy Petri net has been put forward in this paper. In this method, the knowledge in criteria and guidelines is firstly presented in the form of IF-THEN structure through the production rule, based on which the fuzzy Petri net model of fault cause is established then; and lastly possibility of each fault cause can be worked out through matrix iteration, which means the automatic reasoning is completed. Based on fuzzy Petri net imaging, this method makes the reasoning clearer and the result be got faster. The example calculation verifies that the method is correct and feasible in practical projects.
