摘　　要：本文对三轴燃气轮机热力循环计算进行了建模,包含压气机模块、燃烧室模块和透平模块,基于部件性能采用误差矩阵描述燃气轮机运行时部件间的平衡关系.研究了三轴燃气轮机热力循环计算方法.以某三轴MW级燃气轮机为对象,根据由CFD计算获得的该燃气轮机的压气机、透平的性能,计算和分析了该燃气轮机在不同运行工况时的稳态性能,通过与实验测量数据对比.表明热力循环计算结果与实验结果一致.验证了热力循环计算方法的有效性.For the three-shaft gas turbine, the thermodynamic cycle calculation model is devel- oped, whose main body mainly consists of three modules for compressor, combustor, and turbine respectively. The method for the gas turbine performance prediction is researched, based on a set of matching constraints expressed by error matrix and characteristic maps of the related components.. The concerned engine steady-state performance are calculated and analyzed under the compressors and turbines performance that obtained from CFD, and by comparison with the experimental data, the accuracy of the prediction method is validated.
