摘要
清江水布垭水利枢纽是清江干流梯级开发最上一级水电枢纽工程。对电站尾水洞比较了直尾水洞和弯尾水洞两种布置形式。直尾水洞方案出口处水位波动较大,通过模拟计算、三维流仿真计算、水工模型试验,深入研究了泄洪波浪对机组和电网的稳定运行、机组出力和转速波动的影响,以及泄洪波浪引起的压力波动在尾水洞中的传递规律。
There are two comparative schemes of tailrace tunnel of Shuibuya hydropower station, one is straight tunnel, the other is curved tunnel. Owing to the reaction of flood discharge surge, the water oscillation at the exit of straight tunnel is larger than curved tunnel. For this purpose, the transmission of hydrodynamic pressure along the straight tunnel which could affect the rotational speed and operating stability of hydro-units was studied by means of simulating calculation, 3-D unsteady flow emulation and hydraulic model test.
