摘　　要：通风系统是水电站地下厂房的重要辅助设施。水电站甩负荷时,尾水调压井液面波动对地下厂房内的通风设备会产生较大影响。利用数值模拟的方法,建立了水电站通风系统模型,并对某电站的数值仿真。仿真结果表明,只要通风系统设计合理,尾水调压井液面波动对通风设备的影响可以控制在设备允许的范围内。Ventilation system is one of the important facilities in the under-ground workshops of hydropower plants. When hydro tur- bine generator units reject loads, the tail water surge tanks have a great effect on ventilation equipment. This paper introduces how to simulate the tail water surge tank＇s effect on a ventilation system of hydropower station. The simulation results show that the ven- tilation equipment can work normally as long as the ventilation systems are correctly designed by simulating ventilation systems of a hydropower plant.
