摘　　要：风力发电机模型与参数的准确性在研究风力发电对电网的影响时是至关重要的。为研究在系统发生大扰动时风力发电机的动态行为并获得反映实际情况的风电机组模型参数,华北电网公司在张家口地区进行了风电场35 kV母线三相短路试验。文章基于风电场短路试验数据对PSASP仿真平台的双馈风力发电机模型与参数进行了实证分析。首先提出了风机关键参数并对其进行了灵敏度分析,然后根据现场试验数据对相关参数进行了修正,使仿真曲线更加逼近实测曲线,提高了变速风电机组仿真模型的准确度。The precision of model and parameters of doubly fed induction generator （DFIG） are of crucial importance for the research on the influence of grid-connected wind power generation on power grid. To research dynamic behavior of grid-connected DFIG during large disturbance and obtain parameters of DFIG model that can reflect actual condition, a three-phase short-circuit test of 35kV transmission line in wind farm located in Zhangjiakou region is performed by North China Power Grid Company. Based on short-circuit testing data of the wind farm, the empirical analysis on model and parameters of DFIG in Power System Analysis Software Package （PSASP） simulation platform is conducted. Firstly, key parameters of the wind turbine are proposed and the sensitivity analysis on them are carried out; then according to on-site testing data, related parameters of the simulation platform are modified to make the simulation curve more approximating to the measured curve, thus the precision of DFIG model is improved.
