摘　　要：空冷风机的运行状况对整个空冷凝汽器的散热效果起着决定性的作用,主要原因是空冷系统的风机数量较多,运行工况复杂。基于空冷风机的调频功能,利用CFD模拟风机群的运行规律,分析了单个空冷风机单元和风机群在有风和无风两种环境下的运行情况,可为空冷电站实现风机单机和局部调控提供一定的理论依据,并为改善凝汽器的换热效果和风机的耗电提供一定的参考。The running condition of air cooling fan plays a decisive role in the cooling effect of the entire air cooling condenser, mainly due to a large number of air cooling system fans and complexity of operating conditions. Based on the frequency regulation of air cooling fans and by using the CFD to simulate the fan operation, this article analyzed the operation status of single air cooling fan and fan fleet both in windy and windless environment. It provides theo- retical basis for the control of single fan or local regulation as well as reference for improving the heat transfer effect of condenser and power consumption of wind turbine.
