摘　　要：按热力学和热经济学原理,给出了直接空冷系统的优化参数和优化目标函数,并对某600MW直接空冷机组进行优化设计分析,参考运行机组的数据计算出了优化结果。对相关变量进行了敏感性分析,所得曲线表明了选取的设计变量和所得优化结果的合理性,而两个经济性参数的敏感性分析表明电价Pe对优化结果影响较大,因此,电价Pe的定值必须合理。According to the pringciple of thermodynamics and thermal economics, optimal parameters and object function of direct ai-cooled system are given, and an analysis to optimal design is taken to some 600MW direct air-cooled system,the optimal results are calculated in referrence to the operating units. The correlated parameters are executed with sensitivity a- nalysis, the obtained curves show the rationality of chosen design variables and got optimal result, however, sensitivity a- nalysis with two economy parameters indicate the influence of electrovalence Pe on optimal resuh is bigger, so the value of electrovalence Pe must be proper.
