摘要

随着电力行业的飞速发展，电力系统中出现极具危害的混沌振荡可能性增大，维持电力系统稳定的重要性日益突出。通过建立含功率扰动项的四阶电力系统模型，对 Lyapunov 指数、分岔图和谱熵等进行分析，讨论了功率扰动项的加入对电力系统运动状态的影响。同时，基于具有继电特性的切换函数设计了一种动态面滑模控制器，仿真结果表明该控制器在快速平滑抑制系统混沌振荡的同时，能够有效避免抖振问题，并且具有较强的顽健性。

Abstract

With the rapid development of the power industry

the possibility of chaotic oscillation increases in the power system

and the importance of maintaining the stability of the power system is prominent.Through a fourth-order power system model with power perturbation term built

the Lyapunov exponent spectrum

bifurcation diagram and spectral entropy were analyzed

respectively.The influence of power disturbance terms on power system motion was discussed in detail.Moreover

a dynamic surface sliding mode controller was designed based on the switching function with relay characteristics.Simulation results show that the controller can suppress the chaotic oscillation quickly and smoothly

and effectively avoid chattering and own strong robustness.
