    • A method for operating pumps in a pumping-up power plant having a single speed reversible pump turbine and a booster pump, the booster pump being provided in a branch pipe which is provided in parallel with a portion of a draft tunnel between the pump turbine and a lower reservoir, is disclosed. The method includes the steps of initiating the closing of a first inlet valve at the discharge side of the pump turbine, disconnecting the pump turbine and the booster pump simultaneously from an outer electric power system to which the pump turbine and the booster pump are connected, after an opening of the first inlet valve is closed to a predetermined value, and then closing the first inlet valve completely.
