大型汽轮机防进水智能诊断系统的研究

Research on an Intelligence Diagnosis System for the Prevention of Water Induction into Large Steam Turbines

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。

The philosophy for developing an intelligence diagnosis system for the prevention of water induction into steam turbines is discussed and a logic design method for its engineering application proposed.Self generation of a bank of diagnostic rules,retrievability of diagnosis conclusions as well as the application of techniques of trend prediction and mode distinguishment effect a certain degree of intelligence.
