| 摘 要： | 为研究大型风电场接入对电力系统的影响,提出一种变速恒频双馈风电机组动态等值方法。文中首先建立了单台变速恒频双馈风力发电机的数学模型,在此基础之上利用容量加权平均法,分别对风力机、发电机及其控制系统进行等值;然后利用单纯形法对控制系统参数进行寻优,得到风力发电机组的等值模型;最后在PSCAD/EMTDC软件平台下分别建立了风力发电机组的全仿真模型和等值模型,仿真结果表明这种等值方法是可行的。

| Abstract: | In order to study the influence of large-scale wind power integration on power system,the accurate equivalent model of the wind turbine generators becomes the key.Firstly,this paper makes the mathematical model of single DFIG,and on this basis,uses the weighted average method to separately aggregate the wind turbine、generator and control system of the doubly fed induction generators.Then the control parameters are adjusted by simplex searching to get the dynamic equivalent model.Finally,the method is demonstrated to be effective in the PSCAD/EMTDC environment. |
