摘　　要：介绍了直接空冷系统初始温差ITD值的优化理论,阐述了初始温差优选的目的和计算方法。根据动态经济规律分析的方法,以空冷系统年总费用为目标函数,对一台665MW直接空冷机组进行了计算分析,得到了系统最佳ITD值和年总费用。Introducting the optimization theory of direct air-cooling system＇ s initial temperature difference and makes an explanation of the purpose of the optimization and way of calculation. According to the analysis method of the law of dynamic economic, with the total annual expenditure of a direct air-cooling system as the objective function ,the system＇s ITD value was designed optimally to make the total annual cost minimal bying the calculation of a 665MW direct air-cooling unit.

关 键 词：直接空冷系统 初始温差值 年总费用
