基于流体网络技术的汽轮机级组动态模型的研究与应用

根据流体网络中节点的计算方法,将所要求解的级或级组作为压力节点,根据质量平衡和能量平衡计算其排汽压力、排汽焓和机械功,编制了相应的仿真算法,并应用到多个电站仿真系统项目开发中。实践证明利用本文思想编制的汽轮机仿真模型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。

Steam Turbine Stage Dynamic Simulation Model Research and Application Based on Fluid Net Technology

The idea is proposed which the stage or stage-group of the turbine is considered as the press node according to the fluid net technology.And then the discharge press,enthalpy and power of the stage is solved based on the mass and energy conservation law,the simulation algorithm is programmed and been applied to some power station simulators development.The fact is proved that the steam turbine model is able to exactly simulate the working process and the dynamic characteristic of the simulated object,the static characteristic is very precise.
