| 摘 要： | 基于小干扰稳定的概念和分析方法，通过3种不同类型的风电机组，采用PSAT软件中的特征值分析方法，研究风电机组在类型不同、风电场接入距离不同以及风电渗透率不同情况下接入WSCC 3机9节点系统时对小干扰稳定性的影响。研究结果表明:风电机组类型、接入距离以及风电渗透率均会对系统产生不同程度的影响。DFIG的影响优于另外两个机组，在风电机组确定的情况下，距离越近、风电渗透率越低对系统的小干扰稳定性越有利。

| Abstract: | Based on the concept and analysis method of small signal stability, the eigenvalue analysis method in PSAT was used to study, with three different types of wind turbines, the effects on small signal stability when different types of wind turbines were connected to the WSCC 3-machine, 9-bus system with different wind farm access distances and different wind power penetration rate. Results show that the wind turbine type, the access distance and the wind power penetration rate affected the system to different degrees. The effects of DFIG were better than the other two units. When the wind turbine is determined, the closer the distance and the lower the wind power penetration rate, the better stability of the system. |
