| 摘 要： | 近几年,随着大型直接空冷机组(直冷机组)并网发电的普及,机组能否优化运行越来越重要,空冷风机风量的准确计算是机组优化运行的关键.依据空冷风机的性能曲线及风机集群因子,结合相似理论,提出了一种快速计算风机风量的方法,为空冷机组的定量优化提供依据,为相似机组的优化运行提供参考.经验证此方法误差较小,可应用于工程计算.

| Abstract: | In recent years,along with the development of the grid-connected electricity generation of large direct air cooling unit(direct-cooling units),the optimal operation of the direct-cooling units is very important,and its’accurate calculations is the key to optimal operation.This article based on the performance curve and the fan group factor,combined with the similarity theory,comes up witha fast calculation method of fan capacity,providing quantitative optimization for air cooling unit and reference for the similar units.It proves that this method has little error,and can be used in engineering calculation. |
