超临界/超超临界汽轮发电机组甩负荷仿真分析

Analyzing of the Modeling and Simulating for the Supercritical/Ultra Supereritical Turbine's Load Rejection

介绍了超临界汽轮机的运行工作原理,分析了超临界汽轮机甩负荷的工作状态,建立了超临界汽轮机控制系统中部件的数学模型,并建立了超临界汽轮机并网运行的甩负荷模型和仿真模型,给出甩负荷后转速的变化曲线,并分析不同的阀门关闭时间对转速变化的影响。

This paper introduces the running principle of the supercritical turbine, analyses the load rejection work state of the supercritical turbine. This paper establishes the mathematical model of the control system＇ s component and establishes the model of the supercritical turbine＇ s incorporation running of the load rejection, and this paper also establishes the simulation model, The simulation result indicates the load rejection curve of the speed. This paper also analysis the influence of the different valve closing time to the speed.
