1、摘要本文首先分析了燃气一蒸汽联合循环(GTCC)技术当前在国内外的发展现状,以及GTCC的主要特点和各部件的特性和结构特点。然后,文中采用系统工程中模块化思想,将整个联合循环系统划分成燃气轮机装置、余热锅炉和蒸汽轮机几个单元,建立各单元的性能模型,根据系统的生产流程,由前至后实现了GTCC的系统建模。在建立了该模型的基础上,利用Delphi软件,搭建起了一个燃气一蒸汽联合循环系统性能计算的软件平台,通过该平台可以分析燃气一蒸汽联合循环系统的整体性能,最终实现配置的优化。关键词:燃气一蒸汽联合循环Delphi建模ABSTRACTInthispaper,thedevelopmentactualit
