针对强非线性的再热式汽轮发电机组汽门控制 ,提出了一种多变量逆系统全程非线性控制方案 ,以改善电力系统的暂态稳定性。在考虑汽门开度的限幅效应的前提下 ,对单机无穷大系统进行的仿真实验表明 :这种控制方案改善了电力系统暂态稳定的动态过程 ,并且设计过程简明直观。
Aiming at the strong non-linear reheat steam turbine steam valve control, a multi-variable inverse system full nonlinear control scheme is proposed to improve the transient stability of the power system. Considering the limiting effect of valve opening, simulation experiments on a single machine infinite system show that this control scheme improves the dynamic process of power system transient stability, and the design process is concise and intuitive.
