摘要

针对目前众多电力系统混沌控制方法只针对简单2阶电力系统模型的现状以及为了应对电力系统混沌控制时广泛应用的滑模控制中出现的抖振问题及奇异问题

为4阶电力系统提出了一种用于抑制其混沌振荡的协同控制方法:利用分岔图及李雅普诺夫指数谱图找到能使4阶电力系统发生混沌振荡的参数范围; 引入储能装置及静止无功补偿装置的动态模型

从而构成受控的6阶电力系统; 为受控电力系统定义对应的宏变量

设计具有连续控制律的协同控制输入

并给出用于4阶混沌电力系统协同控制的控制框图。数值仿真表明:设计的协同控制器能够使受控电力系统由混沌振荡状态恢复到平衡态

从而有效控制了4阶电力系统的混沌振荡。

Abstract

Many chaos control methods in power systems only focus on a simple two-dimensional power system model. To solve chattering and singularity in sliding mode control widely used in chaos control of power system

a synergetic control method for a four-dimensional power system is presented to suppress its chaotic oscillation. Employing bifurcation diagram and Lyapunov exponential spectrum

the parameter range of chaotic oscillation in the four-dimensional power system is sought out. The dynamic models of energy storage devices and static var compensators are introduced to construct a controlled six-dimensional power system. The corresponding macro variables are defined for the controlled power system

the synergetic control inputs with continuous control law are designed

and a control block diagram for the four-dimensional chaotic power system is obtained. Numerical simulation shows that the designed synergetic controller can restore the controlled power system from chaotic oscillation sta
