摘　　要：以模块化建模方法建立了微型燃气轮机的全工况的动态数学模型,并通过流体网络对其进行了求解。计算及研究了微型燃气轮机从100%到0%范围内的全工况运行的动态特性及甩负荷动态特性,指出回热器壁温蓄能对微型燃气轮机动态特性具有较大的影响。A mathematical dynamic model of micro gas turbines for all operating modes has been established by the modular modeling method and fluid networks used for obtaining solutions. The dynamic characteristics of micro gas turbines, in their full operating range from 100% to 0% load and those of sudden load rejection, have been calculated and studied. In conclusion, it is pointed out that the heat storage in the recuperator walls has a remarkable bearing on dynamic characteristics of micro gas turbines. Figs 15, table 1 and refs 4.
