Fault Diagnosis and Fault Propagation Traceability of Chemical Process Based on Complex Network Method

In order to ensure the safe production of chemical handicrafts, it is necessary monitor process variables system in deal with failures. improve accuracy and monitoring process, whole modeled find out key that cause fault, at same time, impact analyzed propagation path variables. Based on complex network theory, fault node set obtained by combining measured data horizontal visibility map; At constructed, source identified according topology characteristics network. A traceback algorithm proposed determine node; The importance ranking (IR) used quantify focus nodes path. By taking Tennessee Eastman as verification object, results show method can identify occurrence control which proves effectiveness method.
