水轮机调节系统可视化仿真模型研究

由于水力机组数学模型包含有非线性等因素，所以在实际计算及仿真时难于表示。运用仿真软件SIMULINK，建立了一种进行水轮机调节保证计算的可视化仿真模型，在建立模型时，利用水轮机的全特性建立其非线性数学模型，并考虑了调速器的限幅非线性因素，从而使计算结果要比采用近似计算公式的计算结果更精确。所建立的模型具有很强的开放性和可移植性，模型的结构易于修改和重构，能适应水电站个性强的特点，给水轮机调节保证计算提供了一种非常简便易行的方法。

Research of visual simulation model of water turbine governing system

The mathematical model of hydro-turbine contains nonlinear factors,so it is difficult to be expressed in practical calculation and simulation.A visual simulation model for governing calculation of hydro-turbine is established by the software of SIMULINK.In the model establishment,the nonlinear mathematical model is establishment by the characteristics of hydro-turbine and the nonlinear limit amplitude of regulator is considered.Compared with the approximate formula,more accurate result is obtained using this model.This model has powerful capability of opening and transplanting and is easy to be reconstructed and modified,which is suitable to individual characteristics of hydropower station and provides an easy and feasible method for hydro-turbine governing calculation.
