【摘要】 针对在汽轮发电机组振动故障诊断中的不确定性问题,提出了应用贝叶斯网络对其进行推理和诊断。本文介绍了贝叶斯网络的建模方法与推理机制,并通过专家系统的建模过程与诊断实例,证明了应用贝叶斯网络对汽轮发电机组进行故障诊断所具有的独特优点。更多还原

【Abstract】 Aiming at the uncertainty in vibration fault diagnosis of turbine generator unit,the theory and method of Bayesian Networks are proposed for inference and fault diagnosis of turbine unit,the modeling method and inference mechanism are introduced. The u-nique advantages of fault diagnosis expert system based on Bayesian Networks are illustrated by modeling process and diagnosis re-sults of expert system.更多还原
