摘要
应用系统零动态的概念并根据发电机励磁系统的线性化模型，提出了单机无穷大系统多变量励磁控制器设计的新方法。由该方法设计励磁控制器不需要求解Ｒｉｃｃａｔｉ矩阵方程，所设计的反馈增益系数与发电机摇摆模式的阻尼比之间存在着显式关系式。仿真结果表明，本文所提出的设计方法与ＬＱＲ方法比较，设计出的多变量励磁控制器更能有效地改善系统的动态响应。
Based on zero dynamics view point and linearized model of exeitation system,a newapproach of excitation control design for an one-machine to infinite bus power system has beenpresented in this paper. By using the proposed design method.there is no need to solve Riccatimatrix equation. And there is explicit relationship between the designed feedback gain coefficientsand damping rate of swing mode. The simulation results show that the excitation control schemebased on zero dynamics is more effective than one based LQR for improvement of power systemdynamic responses.
