摘　　要：在无法获得汽轮机级组详细的几何参数和气动特性的情况下,根据流体网络中节点的计算方法,提出了将所要求解的级作为压力节点,根据质量平衡计算其排汽压力,按照汽轮机级组做功原理计算其它状态参数和机械功的设计思想,编制了相应的仿真算法,并应用到多套电站仿真系统项目开发中。实践证明,本文的汽轮机仿真模块能够正确反映仿真对象的全物理过程,具有良好的静态精度和动态响应特性,是具有实用价值的通用仿真模块。Under certain circumstances when it is not possible to obtain detailed geometric parameters and aerodynamic characteristics for a steam turbine stage-group one can on the basis of the calculation method for nodes in a fluid network consider the stage to be solved as pressure nodes and based on mass equilibrium calculate steam exhaust discharge pressure.In accordance with the work-doing principle of the turbine stage-group other status-parameters can be computed,and according to the design philosophy of mechanical work a relevant simulation algorithm has been prepared.The latter was employed in the project development of several sets of power station simulation system.General practice has shown that the steam turbine simulation module under discussion can accurately reflect the whole physical process of the simulation object and features fine static precision as well as outstanding dynamic response characteristics.It is a general-purpose simulation module of high practical value.
