Abstract

PURPOSE: To safen a hydraulic machine by opening the highest stage section guide vane smaller than that of another stage section after another stage section guide vane is opened at water wheel start or pump stop.
CONSTITUTION: When a water wheel or a pump starts operating at water wheel start or pump stop after opening the guide vanes 2 and 4, the highest stage section guide vane 4 is opened after first opening another stage section guide vane 2 with the highest pressure stage section guide vane 4 opened and the degree of opening in the highest pressure stage section guide vane 4 is kept lower than that of another stage section guide vane, then the guide vanes are controlled up to the prescribed degree of opening a0. This permits the effect of hydraulic change due to the degree of opening control of the guide vanes to be large only in the extremely limited channel section of the casing 6 or such at the hydraulic duct farther than the highest pressure stage section guide vane 4 to be large and a greater part of channels to be safe from the strength viewpoint.
