基于SIMULINK的水轮机调节系统非线性仿真模型研究

摘要

We can not express the nonlinear of the turbine unit in the calculation and simulation perfectly.So , we settle a matter to use the SIMULINK and give a simulation model to calculate the regulating guarantee. During the modeling,we use the nonlinear factors of Water turbine and governor to establish the simulation model.The model can also be used in other Hydropower stations.It has many advantages ,for examples,it can be more accuracy,more openness and can be modified easily.So,we can know that the simulation model is briefness and workable.%在实际计算及仿真时，机组数学模型中的非线性因素很难表示，运用SIMULINK建立可进行调保计算的可视化仿真模型可以很难好解决此问题，在建模时，利用水轮机的全特性建立其非线性模型，并考虑了调速器的限幅非线性因素，使计算结果较近似公式计算更精确，且该可视化模型的开放性和可移植性都较好，模型结构也易于修改和重构，可以很好的适应了各电站的调保计算，所以应用该可视化模型进行调保计算简单可行。
