Analytical and experimental study has been carried out to verify the performance of pump-turbine runner with splitter blades for super high-head reversible pump-turbines, and the advantage of runner with splitter blades has been made clear from the view point of hydraulic performance. Besides the hydraulic performance, pump-turbine runners for super-high head pump turbines are required to have enough against severe operating condition generated under high pressure high peripheral speed. To evaluate the strength of pump-turbine runner with splitter blades, actual head test and numerical simulation was performed. In this paper, study of super high head pump-turbine runners with splitter blades from the view point of runner strength is described.
