In high head Francis turbines and pump-turbines in particular, Rotor Stator Interaction (RSI) is an unavoidable source of excitation that needs to be predicted accurately. Precise knowledge of turbine dynamic characteristics, notably the variation of

Energy market deregulation and arrival of new players, such as solar and wind turbines, led to an increasing demand for flexible operation of hydraulic urbines. Instead of continuous close to peak operation, it is nowadays not uncommon to see turbine
