摘　　要：采用商业软件Thermoflex对分体式燃气轮机进行模拟,建立了系统的性能分析模型,分析指出压气机转速、透平转速和燃气初温是影响系统变工况性能的主要因素,并对转速和燃气初温变化时系统的输出性能进行了计算分析。通过和共轴燃机的比较分析,得出了分体式燃气轮机的性能潜力。The performance analyzing model of divided-gasturbine was established by adopting the software Thermoflex.By analyzing its off-design specialty,it was found that the rotational speed of gas compressor,gas turbine and fuel gas initial temperature were the main parameters that influence the off-design performance of divided-gasturbine.Then the output characteristic of divided-gasturbine was analyzed with its rotational speed and fuel gas initial temperature changed.By comparing with single-shaft gas turbine,the function potential of divided-gas turbine was obtained.
