| 摘 要： | 以小波分析和信息熵理论为基础，提出尺度熵用于水轮发电机组运行稳定性定量监测的新指标。通过在水电机组监测诊断系统中的实际应用表明，尺度熵较好地反映了机组运行时不同尺度的稳定性．为水电机组的状态监测和诊断提供了运行稳定性的量化数据。

| Abstract: | Based on the theory of wavelet analysis and information entropy,the paper puts forward a new criterion: scale entropy,which can be used for stability monitoring of hydropower sets operation.Analysis of real measured data demonstrates that the proposed criterion can well reveal the stability of the machine operation at each scale,furthermore it can also provide numerical data of stability for condition monitoring and fault diagnosis. |
