摘　　要：通过分析核动力装置的二回路系统,并结合多层流模型(MFM)原理,建立了二回路系统的MFM。利用Visual C++,结合MFM推理规则及因果图(CDG)次序分析法建立了一套测试性的故障诊断系统,并在模拟器上进行仿真试验。结果表明,该诊断系统在故障发生时能准确判定潜在源故障,具有可视化程度高及可理解性强的优点。Based on the analysis of Secondary System of Nuclear Power Plants,a MFM model of Secondary System is established in this paper.Utilizing Visual C＋＋,together with the theory of MFM model and CDG consequence analysis method,a trial fault diagnosis system is built and two simulation cases are used for the evaluating of the fault diagnosis performance.The emulation test proves that the system is able to identify the potential root fault exactly and have the advantage of high vision and understandability.
