摘　　要：本文以永磁风力发电机(permanent magnet synchronous generator,PMSG)作为分布式发电系统节点,以永磁同步电动机(permanent magnet synchronous motor,PMSM)作为感性负载网络节点,研究了分布式发电系统与感性负载网络混沌振荡同步控制。首先基于改进函数投影同步方法设计混沌同步控制器,使PMSG和PMSM实现同步,且通过改变某些参数取值,可以调节同步时间;然后运用李雅普诺夫函数理论证明此方案的可行性;最后数值仿真验证了理论分析结果的正确性和有效性。研究结果对保证电力网络的稳定运行具有重要意义。In this paper,the permanent magnet synchronous generator(PMSG)is used as the node of distributed generation system,and the permanent magnet synchronous motor(PMSM)is used as the the node of inductive load network.Chaotic oscillation synchronization control between PMSG and PMSM is studied.First,the controller is designed by studying the method of modified function projection synchronization,so that PMSG and PMSM can realize the chaotic synchronization control.Moreover,by changing some parameter values,it is found that the synchronization time can be adjusted.Then the Lyapunov function theory is used to prove the feasibility of this scheme.Finally,the numerical simulation proves the correctness and validity of the theoretical analysis results,which are of great importance to the stable operation of power network.
