水电机组故障诊断系统中的模糊诊断技术研究

介绍了在水电机组故障诊断系统中采用的模糊诊断技术,构造了故障诊断的模糊关系矩阵.此模糊知识已成功地应用于实际水电厂的故障诊断系统中,在故障诊断系统的使用过程中得到进一步的充实和验证.在整个系统的多年运行中,此诊断方法成功地诊断出如转子不对中、尾水管偏心涡带等机组运行问题,为电厂的维修与管理提供了有价值的依据与参考。应用效果表明,使用模糊诊断方法于水电机组故障诊断中是有效的,模糊关系矩阵也在故障诊断系统的使用过程中得到进一步的充实和验证.

Application of fuzzy diagnosis to fault diagnosis system of hydraulic generator sets

The fuzzy diagnosis system of the hydraulic Generator sets was introduced.The fuzzy correlation matrix of fault diagnosis was constructed.The introduced fuzzy information was applied to the diagnosis system of a hydropower station.It was enriched and validated in the process of the fault diagnosis system.In these years of the application of the diagnosis system,some problems as the misalignment of the rotor-bearing and eccentric draft tube surges are diagnosed,which becomes a valuable reference for the maintenance and management.The results of application state that the application of fault diagnosis method in power station sets diagnosis system is effective,and the fuzzy relation matrix is enriched and validated in the process of the diagnosis system was carried into execution.
