Abstract

At the pumped storage hydropower plant Kops 2 in Austria a hydraulic shortcut is used to allow the steady transition from turbine to pump operation and hence to enable a smooth transition between energy production and energy storage. During the operation of the plant in the hydraulic shortcut mode the water has to flow in a sharp angle from the turbine conduit into the pumping conduit. The resulting swirling flow has to be minimized for pump operation, which shall be obtained by the construction of a concrete rack in the pumping conduit. The functionality of the rack was investigated using 3D CFD code and additionally controlled and compared with empirical formulas. The methodology and the results of the investigations are presented.
