文章编号:2222-226223-2278-24Modeling and Simulation of a Steam Turbine Proper through the Use of a Sectionalized General-modularizationZhu Wei Jiang Zikang Cheng Fangzhen

Described in this paper is the modeling of a steam turbine proper with the help of a sectionalized general-modularization. Furthermore, with a model C52-92/23 steam turbine being selected as an example, simulation results are given of the steam turbine under various operating conditions and pertinent analyses were also performed. Currently, the above-cited model has been successfully employed for an actual simulation object. Featuring a relatively high precision and versatility in engineering applications, it is suited for simulating steam turbines under various operating conditions.

从52 MW仿真机的实时性和精度要求出发,对C52-92/23型汽轮机在自行开发的电站热力系统及流体网络建模系统的集成环境下,建立各设备和子系统的模块化模型。在仿真机上进行大量的仿真实验,按电厂生产现场数据修正模型,使其更能体现仿真机的全范围特点。由于设备和系统较为复杂,
