摘　　要：为提高现有方法对电力系统振荡混沌的控制效果,基于模糊延时反馈,设计一种互联电力系统混沌控制方法。先构建互联电力系统数学模型,再设计基于模糊延时反馈的混沌控制器;以信号差值微分及信号延时差值为控制器的输入,避免求取反馈增益;利用粒子群算法优化控制器参数,并通过优化的控制器对互联电力系统的混沌进行控制。搭建一个混合输电系统作为实验互联电力系统,通过该系统测试所提方法的应用性能。测试结果表明,设计方法的混沌控制性能良好,证明该方法是一种具有抗干扰性能的控制方法。In order to improve the control effect of existing methods on power system oscillation chaos,a chaos control method for interconnected power system is designed based on fuzzy delay feedback.Firstly,the mathematical model of the interconnected power system is constructed,and then a fuzzy delay feedback chaotic controller is designed based on fuzzy delay feedback.The controller takes signal difference differential and signal delay difference as input to avoid finding feedback gain.The controller parameters are optimized by particle swarm optimization,and finally the chaos of the interconnected power system is controlled by the optimized controller.A hybrid transmission system is built as an experimental interconnected power system,and the application performance of the proposed method is tested through this system.The test results show that the chaos control performance of the design method is satisfactory,which proves that the proposed method is a control method with anti-interference performance.
