In recent years an increased interest in pump-turbines has been recognized in the market. The rapid availability of pumped storage schemes and the benefits to the power system by peak lopping, providing reserve and rapid response for frequency control are becoming of growing advantage. Within the present study a runner-blade profile for a low head pumpturbine has been developed. This paper has been presented during the 25th IAHR Symposium on Hydraulic Machinery and Systems.
The progress in hydraulic design is demonstrated by model test results which show a significant improvement in hydraulic performance compared to an existing reference design.
