本文建立了具有复杂过水系统的水电站机组控制系统的数学模型(引水道和尾水道有调压井或无调压井),通过求状态方程x=Ax+Bu系数矩阵A的特征值,分析了水轮机控制系统小波动的稳定性和动态特性。这种方法同样适用于一般水电站。
In this paper, a mathematical model of a unit control system of a hydropower station with complicated over-water system (tympanic and tailrace with surge tank or no surge tank) is established. By calculating the eigenvalues of the state equation x = Ax + Bu coefficient matrix A, Stability and Dynamic Characteristics of Small Waves in Hydraulic Turbine Control System. This method is equally applicable to general hydropower stations.
