基于多层流模型的一回路报警元件分析算法研究

针对一回路发生故障时报警元件多、信息量大的特点，本文采用了基于多层流模型的方法来分析报警元件，并对警报算法进行了分析。该算法采用因果图原理对报警部件进行深度优先搜索，确定故障报警元件及报警传播路径。基于多层流模型的报警分析系统可作为运行支持系统的子系统来辅助运行人员决策。

Study on Alarm Analysis Algorithm Based on Mutilevel Flow Models for Fault Component of Primary Coolant

In order to analyse alarm of fault components and fault information, this paper utilized the theory of MFM (multilevel flow model) to identify fault components in complex fault situation of primary coolant. This algorithm based on CDG (causal dependency graph) 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.
