Comportement dynamique d'une turbine Kaplan lors d'un arrêt d'urgence - Application au cas de Fessenheim
Dynamic behaviour of a Kaplan turbine in an emergency stop situation - Case study: Fessenheim
EDF-DTG
Abstract
Following rupture of a blade of the Fessenheim Kaplan turbine, investigations have heen carried out to identify the probable causes, and protective solutions to be implemented. This research has led to modification of the blades and wicket gate movement laws during the release phase, in order to limit the risks linked to: exceeding the maximum speed and pressure allowed, lifting the group, appearance of impacts on the runner and draft tube wall.
