摘要
Abstract
The rough set theory ( RST ) and Petri nets were integrated for fault diagnoses of circuit breakers. In order to gain a reduced decision table of circuit breaker fault diagnoses, the RST based di&cemibility matrix algorithm and the rule extraction matrix algorithm were combined to simplify the condition attributes and the rules. The combined method can he used to find the potential rules hiding in the decision table, reduce the workload and the impact of uncertain information, and improve the accuracy of fault diagnoses. Petri nets which integrates the knowledge representation and diagnostic capabilities were built based on the RST extracted rules. By using the parallel reasoning ability of Petri nets, the simplified matrix was caculated to analyze the circuit breaker fault quickly. The correctness and effectiveness were validated by the analysis results of practical fault examples.关键词
