该文讨论了汽轮机防进水事故智能诊断系统的研究思路。从解决工程实际出发，着重提出了适用于工程实践的进水事故诊断逻辑设计方法。通用诊断逻辑组态规则库的自动生成，诊断结论的可回溯性，以及应用趋势预测和模式识别技术，使得诊断系统具有一定的智能性。以该文研究工作为基础的进水故障诊断系统原型机已在电厂投入试运行。图２参２ This paper discusses the research idea of ​​intelligent diagnosis system for turbine accident prevention. Starting from the solution of engineering practice, this paper put forward the design method of diagnostic logic of water intake accident which is suitable for engineering practice. The automatic generation of general diagnosis logic configuration rule base, the traceability of diagnosis conclusion, as well as the application of trend prediction and pattern recognition technology make the diagnosis system have certain intelligence. Based on the research work of this paper, the prototype of water intake fault diagnosis system has been put into trial operation in the power plant. Figure 2 reference 2
