摘　　要：首先建立单机-无穷大系统的三阶数学模型并简要讨论了其动力学行为,指出在一定条件下系统可能会进入混沌状态;然后采用非线性系统无源化方法设计反馈镇定器,并利用L2性能准则进行干扰抑制,使系统大范围渐近稳订,仿真结果表明了该方法的有效性。应用该方法所设计的励磁控制器在改善电力系统的稳定性方面有一定参考价值,对Matlab在电力系统中的仿真应用有积极的作用。Firstly, the three-order mathematical model of single-machine infinite power system is established and its dynamic behavior is discussed in brief. It pointed out that the system may emerge chaos under certain conditions. Then, the passivity method is adopted to design a feedback stabilization controller and L2-gain is adopted to restrain the disturbances, so as to make the system stabilize in global approximately. The simulation results demonstrate the validity of this method. The studies show that the application of the method of excitation controller designed to improve the stability of power systems has a certain reference value. In the meantime, it has positive role in promoting the simulation application of Matlab in power system.
