| 摘 要： | 介绍了电力系统励磁模块控制方式的发展现状，提出一种新的励磁系统控制方法——脉冲控制，阐述了脉冲控制的原理并建立鲁棒稳定性判据，给出励磁系统的数学模型并将脉冲控制应用到系统中；最后通过MATLAB软件在电力系统受到小扰动时，分别对励磁系统使用传统的AVR＋PSS控制及脉冲控制，观察仿真波形；结果表明使用脉冲控制克服了原控制器超调大、响应速度慢等缺点，显著改善了系统性能。

| Abstract: | After introducing the current development of the excitation control method in power system,a novel control strategy---impulsive control is proposed and a set of stability criteria for uncertain impulsive dynamical system and its principle are expounded.Then shows the mathematical model in excitation system and uses impulsive control in this system.Finally,it uses the AVR+PSS and impulsive control in excitation system respectively and observes the curve difference in Matlab when power system is changed into small disorder.The results indicate that using impulsive control can achieve faster convergence speed and faster response and improve the performance of the system remarkably. |
