N2 - This paper considers first the improvement in performance which may, or may not, be achieved with variable speed hydroturbines, with emphasis on hydraulic efficiency at off-design discharge and on the range of off-design discharge operation. Characteristic curves for existing turbines with some means of flow control, such as wicket gates or adjustable blades, are used to estimate the potential improvement in performance at constant head. In addition, the potential of flow control in fixed-blade, fixed-vane turbines operating at variable speed is investigated. Finally, some theoretical calculations are used to support observed trends and discuss the flow control potential of turbines designed specifically for variable-speed operation.
