Abstract: A turbine unit for a hydraulic installation, and more in particular it deals with the hub of the turbine unit. The present invention proposes to provide means for adjusting a gap extent formed between the hub and the inner edge of the blade, this way dramatically increasing the performance of the turbine.

Abstract: This method is for controlling a turbine for a hydraulic power plant comprising at least one reservoir, the turbine comprising a hub having several blades. The method includes running the turbine in at least two different operating modes including a direct power-generating mode and an indirect power-generating mode, when a flow of water fills the reservoir or when the reservoir is emptied.

Abstract: A hydro turbine with a runner unit allows adjusting the gap clearance downstream and between the runner end tip portion and the inner edge of the blades. This gap clearance may depend on the angular position of the runner blades.
