System and method for tracking plant trip cause using data link between plant gateway system and single point vulnerability monitor in CANDU Type NPPs

摘要

The present invention discloses a system for tracking the cause of power failure in a heavy water reactor. The system includes an alarm message collecting unit connected to a remote monitoring network system (Plant Gateway System) of the heavy water channel and collecting an alarm message from the remote monitoring network system, and an alarm message of a power generation stop or output alarm system is extracted The extracted alarm message and the fault tree according to the system are modeled by the vertex of the malfunction of the apparatus, the fault due to the mistake, the human error, and the output shock. And a device tracking unit for detecting a failure cause device based on the fault tree information of the device associated with the alert message.
