| 摘 要： | 将迭代学习控制推广应用到具有强非线性的电力系统中,针对单机-无穷大系统的三阶微分动态方程,对混合型迭代学习控制律的收敛性进行了分析,并首次将其用于同步发电机的励磁控制,通过迭代学习改善励磁控制器的性能,具有结构简单,收敛速度快,鲁棒性强的特点,改善了机端电压的品质。采用Matlab/Simulink仿真软件在单机-无穷大系统中进行了暂态稳定的仿真研究,结果表明该励磁控制方式鲁棒性强,收敛速度快,有利于提高电力系统的暂态稳定性。

| Abstract: | Iterative learning control is generalized to power system with strong nonlinear. The convergence of iterative learning control is analyzed in three-order differential dynamic equation of single-machine infinite system. It is the first time that the control law is applied in the excitation control of synchronous machine. The controller performance is improved by iterative learning, with the characteristic of simple makeup, fast convergence and strong robustness. Transient stability in single-machine infinite system is simulated with Matlab/Simulink. Strong robustness, good controllability and transient stability enhancement are achieved. |
