摘要
针对电力系统负荷扰动满足一定条件时就会产生混沌振荡现象,提出了一种自适应Terminal滑模混沌控制方法。利用Lyapunov指数证明了系统存在混沌振荡,应用简单电力系统分析了周期性负荷扰动下的动力学行为,设计了Terminal滑模动态使得系统能够快速收敛,给出了扰动的自适应律。应用Matlab/Simulink仿真平台对含噪声和不含噪声的电力系统进行仿真验证。仿真结果表明,该控制方法能够有效地镇定电力系统混沌振荡。
According to chaos oscillation phenomena produced by power system load disturbance at certain conditions, a chaotic oscillation control of electric power system based on adaptive terminal sliding mode is proposed. Existence of chaos oscillation in power system is proved by using Lyapunov index. The dynamic behavior of periodic load disturbance is analyzed under a simple power system. A terminal sliding mode is designed for the system to enable the fast convergence. The adaptive law of the disturbance is developed. The model has been described with the reference and implemented by using Matlab/Simulink. Extensive simulation results are presented and analyzed to validate that the proposed simulation model is effective for the suppression of chaos oscillation
