摘　　要：在Cycle Pad中模拟蒸汽动力循环流程时,一旦操作点达到超临界状态,便会超出软件的计算范围。而REFPROP中的热力学参数函数具有很广的计算范围,故本工作尝试在Excel中调用REFPROP中的函数,并通过编程实现了各操作点参数的自动计算。此外,由于REFPROP中有更多的工质可供选择,极大地丰富了模拟计算的内容,对于蒸汽动力循环工质及最佳操作点的研究具有积极意义。Cyclepad is graphic based software for design and calculation of vapor and combined power cycle. However, it can＇t be used when vapor is in the supercritical region. In the work Excel software was developed to overcome the problem by combing a thermodynamic software-REFPROP. As a result, the parameters of operating points can be automatically calculated by programming. In addition, it will greatly enrich the content of the simulation because there is more working fluid to choose from REFPROP. This work will contribute to the design and optimization study of vapor and combined power cycle.
