| 摘 要： | 当机组运行工况恶化而产生非平稳，非线性的振动时，综合应用新兴的小波分析和经典的频谱分析等信号处理技术可以获得丰富的诊断信息。针对兰州西固热电厂５号汽轮机组高压缸大修后的振动现象，描述了汽轮机蒸汽激励故障征兆及其产生原因，指出了减振措施及故障的排除方法。

| Abstract: | Combining wavelet analysis with ordinary FFT spectra is an efficient approach to get abundance information for fault diagnosis, when the machinery come into being nonlinear and nonstationary vibration. A successful diagnostic example is introduced aiming at the acute vibration phenomena of the high-pressure cylinder of the steam turbine generator sets. The mechanism of steam oscillation is studied and sign of this fault is presented. |
