基于“循环函数法”和汽轮机变工况分析理论,建立了适于有二次调节抽汽的单抽、纯凝等各种工况下汽轮机动力特性分析数学模型,设计了合理的模型求解过程,并编制其软件包。研究结果表明,该模型及软件不仅适用于上述工况,而且适用于一次调节抽汽及背压机组、纯凝机组的动力特性分析。
Based on the “cyclic function method” and the theory of turbine working condition analysis, the mathematical model of steam turbine dynamic characteristics analysis under various working conditions, such as single pump and pure condensate with secondary regulation extraction, is established, and a reasonable model solving process is designed , And compiled its package. The results show that the model and software are not only suitable for the above conditions, but also applicable to the dynamic characteristics analysis of once-adjusting extraction and back-pressure unit and pure-condensing unit.
