本文对一个大型太阳能烟囱发电厂（SCPP，又称太阳能上升气流发电厂）进行了数值模拟，模拟中假设了一个具有恒定峰值的日环境温度分布。然后评估了昼夜环境温度差（DATR）对大规模SCPP性能的影响。结果表明，较大的DATR伴随着更大的下降，在夜间的环境温度在夜间增加工厂的功率输出相当大，但在白天的功率输出显着降低。这是因为在给定的太阳辐射输入下，较大的DATR导致从储热层释放更多的热量以在夜间产生更多的功率，而在白天产生较少的热量以产生较少的功率。在这种情况下，日总发电量仅略有增加，但日功率峰谷比（PVR）显着下降是合理的。它还发现，DATR作为一种气象资源的SCPPs是不重要的太阳辐射，但高湿度，在提高发电厂的潜力。与湿度和太阳辐射强度相比，DATR是平滑工厂功率输出的每日曲线的良好因素。
This paper conducts numerical simulations of a large scale solar chimney power plant (SCPP, also called solar updraft power plant) based on an assumed expression of daily ambient temperature profile with a constant peak. It then evaluates the influence of the diurnal ambient temperature range (DATR) on the performance of the large scale SCPP. Results indicate that larger DATR accompanied by a bigger drop in ambient temperature at night increases the plant power output considerably during nighttime but decreases the power output during daytime noticeably. This is because larger DATR leads to more heat released from the thermal storage layer to produce more power during nighttime, and less heat for less power during daytime at a given solar radiation input. In this case, only a little increase in daily total power output but a significant drop in the daily power peak-to-valley ratio (PVR) are reasonable. It is also found that DATR acting as a meteorological resource for SCPPs is not as important as solar radiation, but as high humidity, in terms of enhancing the power potential of the plants. Compared to the humidity and solar radiation intensity, DATR is a good factor in smoothing daily profile of the plant power output.
