Nordic Nuclear Power Generator Stator Vibrations

The foundation for this support is basic knowledge of dimensioning and design requirements with regard to the main components of the stator. To this has been added basic knowledge about excitation and vibrational dynamics, as well as methods for data collection, evaluation and risk assessments.

Actual events are described for the 2-pole generators included in the study as well as adequate and comparable events from external power plants.

Finally, the design of generator maintenance is described with the aim of being able to make adequate and conscious decisions based on the production safety that is sought with identified risks.
