| 摘 要： | 以2机系统为例,将大型双馈风电场划分为2个参数不同的子风电场,对比研究了2个子风电场在汇流线路阻抗不同、容量配比不同的情况下,采用单台风机等值模型与2台风机等值模型时整个风电场次同步振荡特性的差异。分析结果表明,在考虑不同影响因素的情况下,采用单台风机等值整个风电场会引入一定误差,但是风电场参数变化对次同步振荡的影响规律与2台风机等值是一致的。

| Abstract: | Taking the two-generator system as an example, the large-scale DFIG(Doubly-Feed Induction Generator) wind farm is divided into two sub wind farms with different parameters. The SSO(Sub-Synchronous Oscillation) characteristic differences between single-and two-generator equivalent model under different collective line impedances and power generation percentage of the two sub wind farms are comparative studied. The analysis results show that although the wind farm equivalent with a single-generator model may introduce certain deviations considering different factors, the influence of the wind farm parameters on the SSO characteristics still coincides with the two-generator equivalent model. |
