介绍了我公司最近在机组的状态监测和故障诊断领域内,所采用的一些常规分析方法,以及对相位分析在机组故障分析中的认识。同时,通过对汽轮机振因的分析和对一些问题的思考和探讨,力图更深入、准确地掌握设备在实际运行时的多种故障特性,积累更多的故障诊断经验。 This paper introduces some common analytical methods adopted by our company recently in the condition monitoring and fault diagnosis of generating units and the recognition of phase analysis in unit fault analysis. At the same time, through the analysis of the cause of the steam turbine and the thinking and discussion of some problems, it attempts to grasp more deeply and accurately the various fault characteristics of the equipment in actual operation and accumulate more experience of fault diagnosis.
