摘　　要：由于外界条件的干扰或是周期性负荷扰动等原因,互联电力系统运行情况将变得更加复杂,此时,整数阶互联电力系统模型很难准确描述其运行特性.基于分数阶系统稳定性理论,对分数阶互联电力系统模型进行仿真研究.在此基础上分别运用非线性反馈控制和主动反馈控制方法,实现了分数阶互联电力系统混沌振荡的同步控制,仿真结果证明了这2种控制方法的有效性,研究结果对维持电力系统安全稳定运行具有一定的指导意义.Since the interference of external conditions or periodic load perturbation and so on,the operation of interconnected power system become more complex.The integer-order model of interconnected power system was difficult to express its operating characteristics.Based on fractional order stability theory,the model of fractional order interconnected power system was analyzed by numerical simulation.Finally,based on nonlinear feedback control and active feedback control method,the synchronization control was realized for the fractional order interconnected power system chaotic oscillation respectively.Simulation results were given to prove the validity of the two methods.The research maintain the power system＇s security operation.
