针对目前抽水蓄能电站地下厂房自然通风规律尚不明确的问题,在考虑电站运行工况周期变化特点及室外风压的基础上,优化了现有的自然通风网络模型,使其可用于计算抽水蓄能电站地下厂房的自然通风情况。并且,利用优化后的模型,模拟计算了大万山岛海水抽水蓄能电站全年的自然通风情况。结果表明:热压是影响自然通风动力的最主要因素。整体上,自然通风量在冬季大于夏季;单日内,自然通风量受电站运行工况变化的影响。在发电和蓄能工况时,自然通风量较大,在卸载工况时,自然通风量较小。交通洞末端空气温度不受电站运行工况和自然通风量变化的影响,在单日内的变化幅度小于2℃,而在同季节的不同日之间的差异可达8.6℃。在过渡季的部分时段和整个夏季,交通洞末端空气温度高于规定的室内环境温度上限值,因此应开启空调制冷设备。通过优化后的模型与具体案例的分析,为其他类似工程的自然通风系统的设计及运行调控提供参考。
Abstract：Aiming at the problem that the natural ventilation law of the underground powerhouse of pumped storage hydropower station is not so clear at present, the existing natural ventilation network model is optimized on the basis of considering the changing characteristics of the operation cycle and the outdoor wind pressure, and then makes it available for calculating the natural ventilation of the underground powerhouse of pumped storage hydropower station. Moreover, the yearly natural ventilation of the underground powerhouse of Dawanshan Island Seawater Pumped Storage Hydropower Station is simulatively calculated by means of the optimized model. The result shows that thermal pressure is the most important factor to impact the natural ventilation. On the whole, the amount of the natural ventilation is larger in winter than in summer, while the natural ventilation is to be impacted by the change of the operation of the power station within a single day. The natural ventilation amount is larger during the operation condition of power generation and energy storage and is smaller during the unloading operation condition. The air temperature at the end of the traffic tunnel is not impacted by both the operation conditions and the change of natural ventilation amount, for which the changing amplitude per day is less than 2 ℃, while the differences among different days in the same season can reach as high as 8.6 ℃. The air temperature at the end of the traffic tunnel is higher than the specified upper limit of the indoor temperature during a part of the time-intervals in the transition season and the whole summer, thus the air conditioning and refrigeration equipment must be turned on. Through the analyses from both the optimized model and the relevant specific engineering case, some references can be provide for the design and operation control of the natural ventilation system for the similar project.
