| 摘 要： | 建立了适合小干扰稳定分析的风力发电机组的数学模型,用于研究含风电电力系统的小干扰稳定性,推导了考虑同步发电机励磁调节系统动态行为的全系统状态矩阵公式。利用特征值分析法,分析系统的小干扰稳定性。通过算例分析,表明风电场接入系统时,对系统中同步发电机强相关振荡模式的频率影响不大,但当风电出力增加时,相关振荡模式的阻尼增强,有利于系统小干扰稳定性。风电场接入受电端区域时,区域间振荡模式阻尼特性相对差一些,更容易发生振荡。

| Abstract: | A mathematical model of wind power generation sets is established to research the small signal stability of power system with wind farm.The state matrix of the system is deduced with the dynamic behavior of the synchronous generator's with excitation system is considered.Eigenvalue analysis method is used to analysis the small signal stability.The results show that the damping of the power system enhanced when the generation of wind farm increased. |
