METHOD FOR CONTROLLING A TURBINE

摘要

This method is for controlling a turbine (2) for a hydraulic power plant comprising at least one reservoir, the turbine (2) comprising a hub (4) having several blades (6). The method including steps consisting in running the turbine (2) 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. The method comprises further steps consisting in rotating each blade (6) around a longitudinal axis (X6) of said blade (6) between one of the operating modes and another one of the operating modes, so that the orientation of said blade (6) is changed between these two operating modes according to a predetermined rotation angle, selected amongst several predetermined values corresponding to discrete angular positions of each blade (6).
