| 摘 要： | 在某些条件下,电力系统将会产生混沌振荡,从而影响互联电网的稳定性,造成严重的安全事故。通过对简单互联电力系统的时序图、相图及最大李雅普诺夫指数图进行分析,肯定了其存在的混沌现象。同时结合滑模变控制与反演控制,设计了一种反演滑模变控制法,以求能够抑制互联电力系统的混沌振荡,使其迅速收敛于目标。仿真结果进一步证明该方法能够有效地控制系统的混沌振荡,同时具有较强的鲁棒性,对保障电力系统运行的稳定性具有良好价值。

| Abstract: | In some parameters, power system would appear the chaos phenomena, which is hazardous to its stable operation and lead to serious safety accident. Here, the chaotic features of the interconnected power system are analyzed through the time sequence diagram, phase diagram and the maximum Lyapunov index figure. Meanwhile, combining the sliding mode control with backstepping control, a new method to control the chaos of power system is designed, which can quickly make the system reach the expected target. The efficiency and robustness of this method is further demonstrated by the simulation results, and the stability of power system will be in a good value. |
