Experimental study on vortex control measure of water intake and pump station for ADIPALA power plant

In this paper,the current characteristics near water intake,box culvert,fore bay and flow channel were studied according to the water intake and pump house hydraulic physical model test for Indonesia ADIPALA power plant.For the original design,there was harmful air-core vortex near water intake and diversion piers in pump house flow channel.Based on the analysis of vortex appearing,different control measures were used to eliminate the vortex,and ensure the safety of power plant.
