摘　　要：介绍了一个基于热力参数在线监测的核电汽轮机经济性分析与通流部分故障诊断系统。该系统避开了干度测量的困难,利用双重校验方法及基于故障机理的效率修正方法,初步解决了核电机组湿蒸汽汽轮机的热力计算问题。在此基础上,利用神经网络方法建立了基于部件特性参数变化征兆的故障诊断系统,经过检验,取得了满意的诊断效果。A performance monitoring and fault diagnosis system for flow passage of turbines in nuclear power plant was introduced. This system used the double-check method and efficiency correction method based on fault mechanism to partly solve the problems occurring in the heat calculation for wet steam turbine. A fault diagnosis system based on the change signal of the natural parameters was accomplished and proved to be useful.
