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。文中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。同时设计了一种鲁棒反演滑模法对系统的混沌振荡进行抑制,使其能够迅速地收敛于目标。仿真结果进一步证明该方法能够有效性,对保障电力系统运行的稳定性具有良好价值。
In some parameters,power system would appear the chaos phenomena,which is hazardous to its stable operation and lead to serious safety accident.Hereby,the chaotic features of the simple interconnected power system are analyzed through the maximum Lyapunov index figure,the time sequence diagram and phase diagram.Then,we design the robust back-stepping sliding method to control the chaos of power system which can quickly make the system reach the expected target.The efficiency of this method is further demonstrated by the simulation results,and it is of great value to guarantee the stability of power system operation.
