Application of Eddy-eliminating Beam in the Intake of Pumped-storage Power Station

SHI Zhu-hui,CHEN Qing-sheng,ZHOU Chun-tian(College of Water & Hydropower Engineering,Hohai University,Nanjing 210098,China)  
Inspiration eddy at the intake of pumped storaged power station does a great harm to the project by decreasing the flood discharge capacity and the hydraulic mechanical efficiency,as well as causing vibration and noises.It is possible to eliminate the eddy by improving the flow boundary condition at the intake with special structures such as eddy-eliminating beam.By taking the hydraulic examination done in a pumped storaged power station as an example,this paper discussed the eddy-eliminating effect of three kinds of eddy-eliminating beams, and the relations between the arrangement of beams and the eddy strength is also put forward for reference of similar projects.
