ABSTRACT
Large turbosets constitute a major source of electric energy in the world. They are critical machines which are vulnerable to several malfunctions which can decrease their availability and degrade the operation of the national electric grid system. The best source of data for assessment of the technical state are the transient data, measured during run-ups and coast-downs. The size of this data is very large and its analysis can be only performed by highly skilled vibration experts. The goal of this paper is to propose a method, which can apply Machine Learning for automated fault detection. In order to improve the quality of the learning process the method is accompanied by the ‘Digital Twin’ approach, where the simplified analytical rotordynamic model is tuned to a particular turboset and used in the learning process.
