摘　　要：根据抽水蓄能电站的运行调度方式和厂房通风流程的特点,提出将进风洞末端的空气温度作为控制电站通风空调系统运行方案转换的参数,按照满足所有场所的温度参数不超过设计值的原则,推导出通风和空调方案转换的临界温度的计算方法,给出了各温度阶段对应的通风空调运行方案。以南方某装机容量为1200 MW的抽水蓄能电站为例,根据计算所得的临界温度,将进风洞末端全年空气温度划分为4个温度阶段,得到优化后的运行方案,其年运行费用将显著下降。According to the characteristics of production scheduling and ventilation process of pumped storage power station, it is proposed to use the air temperature at the end of the underground tunnel as the parameter for controlling the operation plan of the ventilation and air conditioning system of the power station, according to the principle that the temperature parameters of each places do not exceed the design value, the calculation method of the critical temperature of ventilation and air conditioning conversion is derived, and the ventilation and air conditioning operation scheme corresponding to each temperature stage is given. Taking the pumping power station with a capacity of 1200 MW in the south as an example, according to the calculated critical temperature, the annual temperature at the end of the inlet tunnel is divided into four temperature stages, and an optimized operation plan is obtained. Compared to the current operating plan, the annual operating costs will be significantly reduced.
