摘　　要：针对大规模风电并网后系统小干扰稳定性的变化情况,通过简单系统算例仿真,详细分析了不同风电渗透功率水平下,分别采用固定转速风电机组、双馈感应风电机组和永磁同步直驱风电机组并网对系统阻尼特性的影响,并且通过实际系统仿真算例,验证了分析结果。结合定速风机、双馈风机和直驱风机的仿真结果进行对比分析,对考虑风机并网后系统动态特性因素的风电机组选型提出了建议。In allusion to the variation of small signal stability of power grid after grid-connection of large-scale wind farms, by means of simulation on a simple power system a detailed analysis on impacts of grid-connection of fixed speed wind turbine （FSWT） generators, doubly fed induction generators （DFIG） and permanent magnetism synchronous generators （PMSG） on damping characteristics of power grid under different wind power penetration are given respectively, and the given analysis results are verified by simulation results of actual power grid. Comparative anslysis is performed based on simulation results of FSWT generators, DFIG and PMSG, and considering dynamic characteristics of power grid after grid-connection of large-scale wind farm related suggestions on the selection of type of wind power generators are given.
