汽轮发电机组振动故障的多征兆诊断方法

Vibration Failure Multiple-symptom Diagnosis for Turbogenerator Sets

提出一种考虑多征兆的汽轮发电机组振动故障诊断方法。同时 ,针对采用水平与垂直方向的振动信号往往得不出诊断结果的问题 ,提出一种综合诊断方法。

Presented in this paper is a multiple-symtom diagnosis method for assessing vibration failure of turbogenerator sets. Moreover, to solve the problem of recurring different diagnosis results when vertical and horizontal vibration signals are used, a comprehensive diagnosis method is proposed, which can integrate vertical and horizontal vibration signals.
