With the feature of clustering in Kohonen Network input the energy amplitudes of various of harmonic spectrums about signals of oscillation breakdowns in steam triblet to Kohonen Network as the training sample of breakdowns signals and cluster by Kohonen Network generating the clustering central points .

利用 Kohonen网络聚类的特点， 把汽轮机振动故障信号频谱中的相关 频段 上不同频率谱的谱 峰能量 值作为故障信号的训练样本输入到Kohonen网络，并由网络进行聚类，产生聚类中心点。
