Zusammenfassung:	An apparatus for controlling the operation of a hydraulic machine such as a multi-stage pump turbine having a plurality of runners mounted on a common shaft and guide vanes arranged around respective runners to adjust the flow rate of water supplied to respective runners. The controlling apparatus has a speed detection means for detecting the speed of the hydraulic machine, comparator means for comparing the detected speed signal with a speed command to produce a stroke signal in accordance with a speed deviation signal obtained through the comparison, driving means for opening and closing the guide vanes associated with any selected runner in accordance with the stroke signal, and connecting means for connecting the stroke signal generating means to the driving means for the guide vanes associated with the other runner or runners in such a manner that a predetermined relationship is maintained between the opening degree of the guide vanes of the selected runner and the opening degree or degrees of the guide vanes associated with other runner or runners.
