摘　　要：在火电厂,及时有效地诊断出汽轮发电机组的振动故障对电力生产的安全运行具有十分重要的意义。专家系统是一种设计用来对人类专家的问题求解能力建模的计算机程序。笔者设计了一个汽轮机故障诊断专家系统,它根据现场采集的振动信号等数据,提取出机组运行状态的征兆,根据这些征兆来推断出机组产生故障的原因。It is very important to diagnose the fault based on the steam turbine vibration signal of the thermal power plant timely and effective. An expert system is a computer program designed to modeling the problem solving capacity of human experts. In this paper we designed a Turbine Fault Diagnosis Expert System which is to identify unit operational state signs and to deduce the reason for unit faults according to the recorded data from practical locale.
