摘　　要：以宁夏某电厂350MW直接空冷机组为例,环境风直接影响直接空冷机组的换热性能,针对环境风温对空冷机组影响,数值仿真不同风温、风速、风向对直接空冷机组背压和负荷的影响,分析不利情况,提出降负荷运行。Taking 350MW direct air-cooling unit in one power plant in ning xia as an example, the environmental wind directly affects the heat transfer performance of direct air-cooling unit. In view of the environmental air temperature effecting on air cooling unit, this paper makes numerical simulation of direct air-cooling unit under different air temperature, wind speed and direction of direct air cooling unit back pressure and the change of load, analysising of adverse situation, putting forward the load down.
