Original abstract

The first kind of mathematical modelling is based on the method of characteristic, having implied the transfer equations of a hydraulic machine – water turbine. This mathematical model allows time-dependant change of system parameters such as cavitation cavern volume.In this manner the parametric excited pressure oscillations can be analysed taking into account a harmonic excitation. Results of this analysis are compared to pressure oscillations measured at the partial load operation of a pump turbine.
