汽轮发电机组转子振动故障的动态分层

Dynamic Classification of Turbine Rotator Vibration Breakdown

根据汽轮发电机组转子振动故障具有聚类的特点，运用模糊聚类的方法将转子振动故障进行动态分层，指出在多故障发生与多故障特征的情况下优先诊断的范围，从而缩短了诊断时间，实践表明这种方法是可靠的。

The research on the application of fuzzy set analysis theory to the diagnosis of the trubine rotator vibration breakdown is made in this paper.The appropriate fuzzy set parameters are presented and the prior diagnosis range among the multi breakdowns and multi portents is pointed out.The application of the methods presented in this paper to the actual breakdown diagnosis is satifying,and the diagnosis time can be decreased.
