摘　　要：在周期性负荷扰动情况下,同步发电机可能诱发混沌振荡现象,严重威胁电网运行安全性;为解决此问题,采用精确线性化控制方法来设计混沌控制器;首先,系统的数学模型经过状态变换,对非线性系统进行线性化处理,然后结合配置反馈增益方法,设计出相应控制器;仿真结果表明,所设计的控制器能够有效抑制混沌振荡,发电机转子运行角和发电机相对转速由无规则的运动转变为稳定运行,提高了电力系统稳定性。In the case of periodic load disturbance, the chaos oscillation phenomena may be caused by synchronous generator to threaten the safety operation of the network. In order to solve this problem, a chaos controller is designed applying the exact linearization control. First of all, the mathematic model of the system through state transform realizes the nonlinear systems linearization. Then combine method of configuration feedback gain to design the corresponding controller. The simulation results show that the designed controller can restrain the chaos oscillation effectively. The power angle of the generator rotor and the relative speed of the generator can be converted from irregular movement into stability, so as to improve the stability of the whole power system.
