水电站地下厂房机组部分运行工况下通风空调系统运行方案模型试验研究
Study on ventilation and air conditioning strategy model test in underground hydropower station under part generator operation condition
摘要：
对采用拱顶均匀送风的某抽水蓄能水电站地下主厂房发电机层进行了热态模型试验研究。分别研究了只有1，2，3台发电机组发电时不同拱顶送风方案下发电机层工作区温度场和速度场的分布规律。建议对于采用拱顶均匀送风的地下主厂房，可以减少送风支管的调节阀数量；当发电机组运行台数减少时，根据发电机组的位置，合理调节拱顶两端的空气处理机组运行方式。

Abstract：
Studies the generator floor in the main underground powerhouse of a water energy storage power station with roof air supply by a thermal modeling test. Analyses the temperature field and velocity field under various air distributions with the operation of one to three generators, respectively. Suggests reducing the number of control valves in the air supply branches. When the generators operate in part load，the control of air handling units should be optimized based on the layout of generators.
