Tiivistelmä
The aim of the thesis was to recognize and categorize the common failure mechanisms of turbogenerator stators based on factors such as manufacturer, model year or number of poles. The commissioner of the thesis was TGS Finland Oy.
The type of thesis was a research. The literature research presented the construction of a turbogenerator and the common failure mechanisms. To identify the factors related to the failure mechanisms, the reports of condition monitoring inspections and measurements from years 2010 to 2022 were analyzed.
As the key result of the study, it was identified that catastrophic damages were not limited to machines worn in use, but also appear in new generators, where failure can quickly lead to damages and sudden stoppage of power generation.
In addition, it was found that the machines manufactured in the 21st century had relatively more problems than those manufactured in other decades. Problems appeared regardless of the manufacturer or the model of the machine.
