摘要

提出一种自适应最优励磁控制器(AOEC)。利用递推最小二乘控制技术将发电机和所连接的电网视为控制对象。然后将辨识出的参数提供给一个特殊的3阶离散Riccati方程，实时求解该方程得到最优增益矩阵。在单机无限总线系统的物理模型上进行了动态仿真，验证了AOEC的有效性。并在葛祖坝水电站进行了一些试验。自2003年3月起，AOEC在葛洲坝水电站开始运行。验证了其可靠性。

Industrial Application of the Adaptive Optimal Excitation Controller

An adaptive optimal excitation controller (AOEC) is presented. The generator and the power grid connected are identified as an object controlled with recursive least square technique. Then the parameters identified are provided to a special 3 order discrete Riccati equation which is solved in real time to get optimal gain matrix. Dynamic simulations were carried out on a physical model of a single machine infinite bus system to verify the effectiveness of the AOEC. Some experiments were also carried out in Gezouba hydropower plant. The AOEC has operated in Gezhouba hydropower plant since March, 2003. Its reliability is verified.
