“…At present, dozens of air-cooling units in the condenser are controlled as one unit, but the fans in different positions of the condenser have different performances under the ambient wind. Referring to the divisional control suggestions presented by previous studies [7,[16][17][18], four division schemes were proposed for the direct air-cooling array according to the wind direction, as shown in Figure 11. The axial fans were divided into three groups according to the wind direction: windward fans, leeward fans, and other fans.…”

“…Installed on an outdoor platform with a height of tens of meters, the performance of the direct air-cooling condenser is affected by factors such as turbine steam load ratio, fan speed, ambient temperature, wind speed, wind direction, and windscreens [4][5][6][7]. Flow distortion or disturbance caused by wind can negatively impact the performance of the condenser, resulting in complex fluctuations in fan inlet flow and temperature.…”

“…He et al [21] found that increasing the installation angle of fans properly can improve the net power of the direct day cooling power plant. Furthermore, they studied the adjustment schemes of the fan rotational speed [22,23] and declared that increasing the speed of upwind fans or the fan array is useful for the power-generating unit and adjusting the windward ACC cells is better than adjusting the leeward ones. Li et al [24] investigated the optimal frequency of fans under different unit output power and environment conditions to maximize the net power, and they recommended increasing the capacity of ACCs so that the fans can operate at the optimal frequency under high loads.…”

“…From the aforementioned research, it can be concluded that the operation regulation of axial flow fans is an easy and effective method to combat the ambient wind. He et al 23–25 found that adjusting the blade angle or the fan rotational speed is helpful to increase the net power of the direct dry cooling power generating unit. Huang et al 26 proposed the method of partition adjustment of fans to reduce the turbine back pressure under windy conditions.…”
