Method for monitoring rotating machines

摘要

The method involves tracking time characteristics of specific sensor data, during monitoring operating phase. The first diagnosis SOM with subset of specific sensor data is prepared in reference operating phase. Three-dimensional (3D) graph of first diagnosis SOM is evaluated to identify a fault cause. The second diagnosis SOM is prepared, when identification of fault cause is unsuccessful. Second diagnosis SOM is evaluated to identify the fault cause for checking a starting model. The rule set is modified based on evaluations of reference and diagnosis SOMs.
