Abstract: In this paper, the cam curve selection methodology of the largest Kaplan turbine unit is discussed. The cam curves generated by both index test and stability test are presented and analysed. To compare with the current cam curve running the power plant, the efficiency cam curve increases the unit efficiency by around 1%; while the stability cam curve has decreased the vibration with a small cost of output (less than 2%). The research gives the operators of hydraulic turbine unit a guidance of selecting the optimal operation strategy.
