Study on the Influence of Tailrace Tunnel Outlet Bottom Slope on Water Level Fluctuation in the Tailrace Surge Tank

Abstract:

Combining with hydraulic model experiment of water diversion and power generation system of one hydropower station, the effects of different connection patterns between the tailrace tunnel outlet and downstream river bed and flow states in the transient process on the water level fluctuation in tailrace surge tank have been investigated. The results show that: there is not remarkable influence on water level fluctuation when tailrace water level in downstream river is higher or close to the ceiling height. On the opposite side , it has notable influence on water level fluctuation in the tailrace surge tank when tailrace water level in downstream is lower than the ceiling height, and the water level fluctuation in tailrace surge tank presents some regularity under the same connection pattern when the tailrace water level in downstream river is lower than the ceiling height.
