摘　　要：关于大容量并网风力发电对电网稳定性影响问题,由于环境条件的影响,风力发电引起的暂态稳定性变化较大。为解决上述问题,在采用PSS/E软件构建异步风力发电机及IEEE-9节点仿真平台的基础上,考虑风力发电机自身特性及参数,分析风电结构特性参数对自身暂态稳定性的影响力。指出异步风力发电机的松弛刚度及发电机定子电抗X S、转子电抗X r、转子电阻R r对风力发电机的暂态稳定性影响力较强,而定子电阻R S与励磁电抗X m的变化对风力发电机的暂态稳定性影响力较小。The large-capacity grid-connected wind power generation increasingly impacts the power grid, the transient stability of the wind turbine becomes an important point. Using the PSS/E software, the asynchronous wind generator and IEEE-9 node simulation platform were built. This paper considerd the own characteristics and parame- ters of the wind generator, and analyzed the impact ability of wind power structural characteristic parameters on the transient stability. The results show that the generator relaxation stiffness and generator stator reactance Xs , rotor re- actance Xr , and rotor resistance Rr, impact the transient stability more obviously, while the stator resistance Rs and magnetizing reactance Xm have less impact on the transient stability.
