过渡季节抽水蓄能电站地下厂房排风设施布置方式数值模拟

Numerical Simulation of Arrangement of Ventilation Facilities in Underground Powerhouse of Pumped Storage Power Station in Transitional Season

抽水蓄能电站地下厂房通风效果对电站的安全高效运行具有重要意义。为研究内蒙古赤峰抽水蓄能电站地下厂房的通风效果,建立了地下厂房总排风机地上与地下两种布置方式的数值计算模型,通过与模型试验进行对比,验证了数值计算方法的可靠性。进而对比研究了总排风机两种布置方式的数值模拟结果,发现地下式总排风机房布置方式对厂房内的空气流通驱动作用较大,沿程损失较小,与地上式总排风机房布置方式相比,排风效果更佳。

The ventilation effect of underground powerhouse in pumped storage power station is of great significance to the safe and efficient operation of power station.In order to study the ventilation effect of underground powerhouse for Inner Mongolia Chifeng pumped storage power station,the numerical simulation was carried out for the arrangement of the exhaust fan on the ground and underground.The numerical simulation results were compared with the model test to verify the reliability of the numerical calculation method.By comparing the simulation results of the two arrangements of the general exhaust fan.it is found that the arrangement of the exhaust fan in the underground has a greater driving effect on the air circulation in the underground powerhouse.and the loss along the way is smaller.which is better than the ar-rangement of the exhaust fan in the underground.
