ABSTRACT:
A method for controlling operations of hydraulic machines, in which two or more hydraulic machines are positioned in water conduits separated or branched upstream thereof with the branch water conduits downstream therefrom being joined together or maintained separate. Thus, these hydraulic machines are communicated with each other through the branch water conduits. In this method, the lower limit of a closing operational speed of guide vanes in one hydraulic machine is preferentially or overridingly controlled in the transient phase of operation, by detecting the closing operational speed of guide vanes of the other hydraulic machines. As a result, an abnormal condition in hydraulic pressure in upstream or downstream water conduits may be prevented, which condition would be caused in the event that the operational conditions of respective hydraulic machines are abruptly changed one after another.
