Abstract
The invention relates to a method of operation of a pump-turbine between part-load and reverse pumping operation in which the various operating conditions are produced by changing the position of the wicket gates in that some of the wicket gates are removed from the synchronous operation as provided by the mechanical gate ring operator and inserting a servo-motor between the wicket gate and the gate ring which functions to alter the connection between the selected wicket gates and the gate ring operator.
