Abstract

For a circuit failure alarm devices and more informative features, we use the method based on multi-flow model to analyze the alarm devices, and alarm algorithm is analyzed. The algorithm uses the principle of cause and effect diagram components of the alarm depth-first search to determine the fault alarm devices and alarm communication path. Flow model based on multi-alarm analysis system can be run as a support system to assist operating personnel decision-making subsystem. In order to analyse alarm of fault components and fault information, this paper utilized the theory of MFM to identify fault components in complex fault situation of primary coolant. This algorithm based on CDG can perform depth- first search of alarm components, confirm the root cause of alarm component and the path of alarm propagation. Alarm analysis system based on MFM can be used as sub-system of operation support system to assistant operators to make decision
