汽轮发电机组故障诊断问题的研究

A Study on Problems of Faults Diagnosis of Steam Turbine Generator Units

从系统论的角度分析了汽轮发电机组故障诊断问题的特征有：故障的阶段性、渐进性、并存性；征兆的相关性；数据和信息的不充分、不可靠性；征兆和故障的复杂映射性及故障表现的不一致性。根据这些诊断系统特征的需要采取了相应的措施，为汽轮发电机组故障诊断系统的研制提供了基础。

Proceeding from the system theory,the features of fault diagnosis for steam turbine generator units are:fault developing by stages,gradual developing,coexistence of different faults,correlation of signs,insufficiency and unreliability of data and information,complex reflexivity of fault and its sign,and inconsistency of their representations,Based on these features,measures are taken accordingly,which form the basis of the fault diagnostic system of steam turbine generator unit.
