摘要： 研究分布式发电系统中感性负载的稳定性对保证电网正常运行有重要意义。本文以永磁同步电动机（permanent magnet synchronous motor， PMSM）作为实际感性负载，以二阶Kuramoto模型作为分布式发电系统，建立一个新的具有网络耦合作用的数学模型，分析分布式发电系统与感性负载之间的外部耦合参数对PMSM稳定性的影响。数值仿真结果表明：随着耦合参数的增大，原来不稳定的PMSM由混沌运动转变成稳定运行状态，达到系统自身的一个平衡点；外部耦合参数越大，PMSM达到稳定状态的速度越快。该研究结果对保证PMSM并网后的稳定运行具有重要意义。

Abstract: The stability of inductive load in distributed generation system is studied. Firstly, the novel mathematical model with a coupled system is established, where the permanent magnet synchronous motor (PMSM) is regarded as a practical inductive load and the second order Kuramoto like model is considered as a node of distributed generation system. Secondly, the effect of the stability of PMSM caused by distributed generation system and the external coupling coefficient is analyzed. Finally, the results of the numerical simulation show that the value of external coupling coefficient can make the unstable chaotic PMSM transform into a stable balance point, and the larger coupling coefficient is, the faster level of stability can PMSM achieve. Hence, the results of the experiment has great significance on ensuring the stable operation of the PMSM.

Key words: permanent magnet synchronous motor, distributed generation system, stability analysis, second order Kuramoto model
