摘要

提出了直接空冷系统优化设计的参数和优化目标函数

并对某台600 MW直接空冷机组进行了优化设计。根据直接空冷机组的传热方程

定量分析了环境温度变化对机组运行经济性的影响

结果表明环境温度变化对机组运行经济性影响较大

对此

提出了控制风机群运行状态以达到经济运行的目的。

Abstract

The design optimization parameters and optimizing object function of the directing air cooling unit have been put forward

and design optimization of a 600 MW direct air cooling unit being carried out.The influence of ambient temperature variation upon the economic efficiency in operation of the unit has been quantitatively analysed on the basis of heat transfer equation for the direct air cooling unit

the results show that the ambien temperature variation has greater effect upon the economic efficiency in operation of the unit

hence a scheme of controlling the running state of fan groups being put forward for reaching the target of economic operation.
